ATmega328P mods this console controller

Marcel Smith has modded and tricked-out a PS3 dualshock controller using an ATmega328P microcontroller (MCU).

Additional key components and features include:

  • Supports Arduino bootloader
  • 
Programmable via USB
  • Dual force feedback
  • 2.4GHz 60mW Xbee pro module (optional)
  • 2.4GHz Wi-Fi module (optional)
  • Low profile pinheader
  • Wireless module configuration via USB port
  • Open hardware/software
15 digital buttons
  • Two analog triggers
, two analog joysticks
  • 3.7V Lipo battery
  • USB auto battery charge
  • Borderline 0uA standby current

The modded device – which recently surfaced on Indiegogo – is aimed at DIY Makers and hobbyists interested in a versatile remote control platform.

“You can use and program the controller for robotics, RC cars, planes, helicopters, drones, boats, hovercrafts and FPV,” Smith explained.

“The controller uses an ATmega328P, the same as on the Arduino Uno. This makes it easy to adapt the Arduino platform on the controller. You can upload your sketches via the USB port. The hardware and software is open for everyone, this makes it possible to program your own functionality into the controller.”

Makers can also directly configure the Xbee/Wi-Fi module via USB using X-CTU by simply setting the UART software switch in the right direction.

“The controller sends serial messages to the USB port, so even without wireless module it is possible to control something like a game on your computer with the controller (force feedback),” Smith added.

Eric Pan: From Seeed Studio to HAXLR8R

Born in Sichuan, China, Eric Pan (潘昊) graduated with an Electrical Engineering degree from Chongqing University. 

He founded the wildly popular Seeed Studio in July 2008 to help Makers transform their ideas into actual products, subsequently establishing the first organized Maker Community in Shenzhen. Known as Chua Huo, the MakerSpace facilitates interaction among DIY Makers, while encouraging dialogue and cooperation with both industry and academia.

Eric is understandably enthusiastic about the open source movement, as he also organized the Shenzhen Maker Faire and established the hardware incubation project “HAXLR8R” with Cyril Ebersweiler. In 2013, Eric was named one of the “Top 30 Entrepreneurs” in China by Forbes, which prominently featured the engineer on the magazine’s front cover.

Recently, the staff of Bits & Pieces had the opportunity to sit down with Pan for a wide-ranging interview covering a number of topics including the rapidly evolving open source movement, Atmel-basedArduino boards, Atmel-powered 3D printers such as RepRap, the Maker Movement and Shenzen, a major city in the south of Southern China’s Guangdong Province.


Bits & Pieces: 

How are Atmel-based Arduino boards and 3D printers such as RepRap helping to inspire the design and prototyping of new products in China?

Eric Pan:


Hardware development has traditionally been perceived as a complex process, with a product lineup often taking years to improve and perfect. However, tools such as Atmel-based Arduino boards and 3D printers have significantly lowered the entry barrier for hardware innovation, thus creating a much wider playing field for DIY Makers. 

Indeed, over the past a few years, we’ve seen designers and Makers create prototypes and iron out issues in days and weeks, rather than months or even years.

Clearly, hardware development is becoming a more agile process with the aid of prototyping tools like RepRap and Arduino boards – both of which are helping to facilitate innovation across the world and particularly in China.

Bits & Pieces: What role do MakerSpaces and Universities play in setting technology trends for Chinese tech companies?

Eric Pan: 
Universities have established links and collaborated on a number of projects with various Chinese tech companies, with many engaging in pioneering research. In addition, MakerSpaces have evolved into innovation hubs responsible for encouraging a diversity of ideas and products. 

Essentially, MakerSpaces act as a virtual bridge for cross-boundary conversations between industry and academic research. This enables constructive dialogue about issues which are typically overlooked. Personally, I believe niche market Maker platforms and devices are analogous to indie movies that provide the commercial film industry with a hotbed of new ideas.

MakerSpaces will likely enable a new wave of tech startups in China as in the US. To be sure, Makers working with their peers are now able to more easily realize their goals, while bringing products to market with new platforms such as e-commerce sites and crowdfunding. 

Nevertheless, major companies in China are somewhat cautious about encouraging grass-root innovations, even though some of them are actively involved in a collaborative dialogue with Makers as part of a strategic open innovation strategy. So for now, MakerSpaces are gradually helping Chinese tech companies discover additional possibilities, although the Maker role is likely to increase, with participants in the DIY culture setting technology trends in conjunction with major industries.

Bits & Pieces: The Maker Movement seems to be particularly active in Shenzen and Shanghai. Why do think this is?

Eric Pan: The most important factor is the intellectually fertile ground of the two locations. Shanghai is particularly active, first and foremost because of its foreigner base and natural Maker culture.

Local tech and art people are also enthusiastic about the trend, which helps bolster the DIY attitude. 

Meanwhile, Shenzhen has an established manufacture and supply based chain which is attractive to Makers from all over the world. If you look at the bigger picture, it is quite clear that these local two MakerSpaces have inspired a larger group of Makers and Makers-to-be across China. 

Unfortunately, the cost of living in both Shanghai and Shenzhen are too high for many Makers to realistically design and develop their products. As such, I hope to see more Makers gathers in smaller cities where the cost of living is somewhat lower and more amenable to a DIY crowd.

Bits & Pieces: What is the future of open source hardware and the Maker Movement in China? Does it face any specific hurdles?

Shenzhen (Image Credit: Wikipedia)


Eric Pan: 
There are currently a number of opinions being heard about the future of the Maker Movement in China. Nevertheless, one thing is for certain. The inherent entrepreneurial spirit of the Chinese people will help the Maker culture grow – and vice versa. 

The biggest hurdle, from what I can tell, may very well come from established educational facilities, simply because Chinese students expect to be trained in traditional methods when specific professional skills are required. 

However, exposure to multiple academic disciplines will encourage people to people think out of the box and explore different ways of approaching problems and opportunities. In addition, being asked more open-ended practical questions instead of simply memorizing facts would go a long way in encouraging students to try out real-world solutions.

Bits & Pieces: What can companies like Atmel do to help encourage the growth of the Maker Movement in China?

Eric Pan: Atmel has already played a very important role in engineering universities through its programs. The inspiring part is that art and design students are using Atmel chipsets which power Arduino boards – effectively building a bridge for major cooperation between Makers and the corporate world.

Continued support from Atmel for future Maker events will definitely contribute to the evolution and growth of the DIY movement in China. On the business side, hardware generated by Maker projects will also help encourage major industry players to create more varied products using Atmel microcontrollers and microprocessors. Last, but certainly not least, the direct involvement of Atmel engineers in local Maker communities will undoubtedly help nurture and grow the DIY movement across China.

Arduboy is an uber-mini game console



A Maker by the name of Kevin has created an uber-mini handheld game console using Atmel’s ATmega328p microcontroller (MCU).

As HackADay’s Brian Benchoff notes, the Arduboy build utilizes a number of unique design techniques.

“The inspiration for this project began when [Kevin] dropped an SMD resistor into a drill hole on a PCB. This resistor fell right through the hole, giving him the idea creating a PCB with milled cutouts made to fit SMD components,” Benchoff explained.

“With a little experimentation, [Kevin] found he could fit a TQFP32 ATmega328p MCU in the Arduino – in a custom square cutout. [Additional] components – including a CR2016 battery and OLED display- use the same trick. The rest of the design involved taking Adafruit and Sparkfun breakout boards, modifying the individual circuits until something broke.”

Kevin’s unconventional PCB design approach ultimately resulted in a handheld game console that measures only 1.6 millimeters thick – and boasts capacitive touch sensors for controls.

So what’s next for the Arduboy? Well, Kevin says he wants to release the design files and source code under a fully open source license and launch a crowd sourcing campaign.

“I also would like to sell [Arduboy] kits on my site and on Tindie,” Kevin wrote on the project’s page.

“[Plus], I would like to design the board with four layers and place the circuit traces entirely on the board interior. This would allow for test points to be placed in standard ISCP and FTDI configuration, eliminating the need for an otherwise custom bed-of-nails programming interface.”

Reza Kazerounian talks IoT and MCUs (Part 2)



EEWeb recently conducted an interview with Reza Kazerounian, Senior VP and GM of the Microcontroller Business Unit at Atmel. In part one of our synopsis, we reviewed how Kazerounian defined the Internet of Things, detailed the company’s comprehensive IoT portfolio and discussed Atmel’s relationship with the rapidly growing DIY Maker Movement.

Kazerounian went on to confirm that Atmel is currently working with a number of customers to market various IoT applications.

reza1cropped

“These customers range from smart metering, to industrial, consumer applications similar to Nest, [as well as] medical and white goods. Many of these customers have been working with Atmel for years and are in production with our technologies today,” he explained.

“With the dawn of the Internet of Things, these products are being categorized under a broader market—the IoT. An example includes connected thermostats in the home and building automation sector, [which] have [actually] been around for a while.”

However, says Kazerounian, it was not until recently that such devices were considered mainstream.

“It took mass adoption of smart tablets, smartphones and other smart consumer devices to enable more of these ‘connected’ devices to be easily accessible to the Internet and available at a cost-effective price point,” he added.

Indeed, “separate” technologies for IoT have been around for some time, but the requirements to seamlessly run numerous technologies simultaneously took longer to achieve.

“For example, connecting your smartphone at home to control your lighting is becoming a reality today. Another important factor for the IoT is wireless connectivity. These connectivity solutions operate on a number of different standards including Wi-Fi, ZigBee, Bluetooth, and others,” Reza continued.

smarthome

“For IoT applications, it’s important to adopt the right wireless standard based on the application and consumer requirements. For example, if you want a device that is connected to a wireless network at home and can traffic the data with a high data rate, Wi-Fi is the most viable type of technology. For wearable devices, you would need a wireless connection with the lowest power consumption available since many of today’s wearable devices run on batteries.”

Kazerounian also noted that the IoT landscape is populated by applications with embedded processing and connectivity requirements that offer companies such as Atmel an advantage.

“[Indeed, we] made a recent investment in our connectivity portfolio over a year ago [by] acquiring Ozmo Devices, a Wi-Fi connectivity company. Adding to our broad wireless product portfolio, this strategic acquisition helped us enhance our Wi-Fi connectivity solutions, an important part of our strategy for targeting the IoT market,” he said.

atmelzigbit

“Atmel also has a broad portfolio of touch technologies, from capacitive touch buttons, sliders and wheels to touchscreens. As sensors and sensing nodes become an important part of the IoT ecosystem, our embedded processing solutions can combine input from multiple sensors to provide real-time direction, orientation and inclination data to bring visibly superior performance to gaming, navigation, augmented reality and more.”

Reza concluded his interview with EE Web by emphasizing that Atmel views microcontrollers (MCUs) as an essential building block for every PC, consumer device, industrial machine, home connectivity device and automobile. To be sure, MCUs are playing an increasingly critical role in the lucrative space.

“As the semiconductor industry has transitioned from PCs to mobile, IoT will now rise to become the predominant market,” Kazerounian explained. 

”This transition will favor ultra-low power and integration of microcontrollers, wireless connectivity, security, touch technologies and sensor management products. Atmel is uniquely positioned and fully committed to maintaining our leadership position in the microcontroller industry – and to do so requires winning in the IoT.”

Reza Kazerounian talks IoT and Makers (Part 1)

Reza Kazerounian, Senior VP and GM of the Microcontroller Business Unit at Atmel, recently sat down with the folks at EEWeb to discuss a wide range of topics including the Maker Movement, the rapidly evolving Internet of Things (IoT) and the future of Atmel’s MCU business.

As Kazerounian notes, the IoT is a combination of multiple market segments, tens of thousands of OEMs and hundreds of thousands of products.

“It is seen by many as the next wave of dramatic market growth for semiconductors. If you look at the different estimates made by market analysts, the IoT market will be worth trillions of dollars to a variety of industries from the consumer to financial, industrial, white goods and other market segments,” he explained.

“Companies that provide cloud-based services, service providers and semiconductor companies will also benefit from this market. The number of small or new companies that are showcasing connective devices has increased – there will be 50 billion connected devices by 2020. These nodes will have characteristics such as low-power embedded processing, a human-machine interface and connectivity.”

That is precisely why Atmel has consolidated the most complete portfolio of IoT technologies: ultra-low power microcontrollers, wireless connectivity, touch controllers, touch materials (XSense), sensor management and security.

“These key IoT ingredients combined with Atmel’s development environment, culture and global support infrastructure will enable us to offer the broadest and most comprehensive IoT solutions in the industry,” he said.

atmelsamd20mcu

“Atmel is a leading supplier in embedded processing. We compete in the low-power technology market segment because many of the near-home devices have been around for many years and have the ability to be connected wirelessly. These devices include gateways such as routers, access points and more.”

Kazerounian also discussed Atmel’s relationship with the burgeoning DIY Maker Movement which espouses an open hardware philosophy.

“More designers are initially starting with [Atmel-based] Arduino boards for their prototypes, and these designers will eventually become our customers. The Maker community is continuing to grow and is influencing how designers jump-start their first design to accelerate their prototype development,” Kazerounian continued.

“This trend will potentially increase ROI. Atmel is seeing an increase in professional engineers relying on [Atmel-based] Arduino boards to create initial models for their prototypes. The net impact of the Maker movement is the accelerated development of products which contribute to the overall IoT market growth and will ultimately benefit Atmel.”

Open Screen Adapter (OSCAR) goes AVR

OSCAR is a super high resolution 9.7″ screen with an Atmel-powered adapter that allows users to easily link the display to their PC, Mac or Linux machine.

“The board is Arduino compatible which makes modifying the behavior easy and all the software and hardware is open source,” OSCAR spokesperson Freddie Temperton explained in a recent Kickstarter post.

“The particular display used with OSCAR is the one most commonly found in the iPad 3 and 4, marketed as the ‘Retina Display’ and has a whopping 2048×1536 pixels. This gives it an amazing pixel density of 264ppi (pixels per inch) and glorious colors.”

Key OSCAR specs include:

  • Atmel ATmega32u4 microcontroller (MCU)
  • Supports DisplayPort/Thunderbolt (via a small connector)
  • Takes 12V 1A input (9-12V recommended)
  • Consumes a nominal 6W
  • Software upgrades via a micro USB port, allows the computer to control the backlight and power to the display
  • TPS61176 backlight drivers
  • LMZ12001 high efficiency buck regulator
  • All spare IO pins available on 0.1″ pitch headers (6 analogue pins, 9 digital, I2C, SPI, serial and 5V power RGB LED for OSCAR status)

“OSCAR takes care of driving the LED backlight and regulating the panel power supply. With the onboard ATmega32u4, the device acts like an Arduino Leonardo. This enables USB communications so that you can use OSCAR to control things like backlight brightness and enables you to expand the functionality of OSCAR,” Temperton explained.

“Adding an IR receiver for control or adding an IMU board to automatically rotate the screen are all possible. As you can use the Arduino IDE, customization is easier than ever to implement. There are also drivers for the LED backlight so brightness can be adjusted using a PWM output from the microcontroller. [Plus], buttons are included to turn the display on/off and to increase or decrease the backlight brightness.”
