Beta Board Preview. Colorduino running the Plasma demo. The Colorduino takes a lot of the difficulty out of of controlling an RGB LED matrix, something I was stumped with as a beginner in electronics. Its built around the ATmega. CPU, the heart of the Arduino platform, and builds on previous matrix controllers like the Rainbowduino from Seeed Studio.

Tead have made sure the Colorduino is pin compatible with the Rainbowduino so it can slot in with existing projects, but have upped the specifications to get better performance. The Colorduino board. Spectrum What Came Before After Rar' title='Spectrum What Came Before After Rar' />While other landfills in the area have been used for retail, nothing on the scale of what Relateds asking for has been approved before. Keith Roberson, senior. ITead have taken on Rainbowduinos Plug and Shine ethos, making Colorduino ideal for beginners. I found setup really simple after plugging in the LED matrix. One of the Colorduinos main features is that it uses a DM1. LED driver chip to provide hardware PWM. This allows each Red Green and Blue channel to have an 8 bit colour depth, resulting in a theoretical 1. As a comparison the Rainbowduino uses software PCM to achieve a 4 bit colour depth thats 4. Whether all those 1. Tead say their approach provides more accurate colour control than other boards. The DM1. 63 chip also provides 3 x 6bit correction registers, useful for calibrating the respective brightness of each color channel in software. This can be used for example to adjust the white balance of the display. Colorduino left and Rainbowduino. Colorduino and LED matrix from Cool Components. The physical board is a little smaller than an LED matrix and is designed so multiple Colorduinos can be plugged together to make larger grids of LED matrices. Data is passed between boards using the I2. C protocol. I2. C is well supported on the Arduino and there is lots of demo code out there to get you started. Power to the board is either via pin headers or 2 sets of mini screw terminals. A slide switch selects between the two. Various Pins are brought out the edge of the board including RX, TX and DTS, which can be used to reprogram the onboard ATmega chip, and SCA and SCL for I2. C communication. A green LED on the front of the board indicates power, although it is mostly obscured as soon as you plug the matrix panel in. A schematic of the board and demo code is available here. Colorduino rear showing pin connections. Tead have taken on Rainbowduinos Plug and Shine ethos, making Colorduino ideal for beginners. I found setup really simple after plugging in the LED matrix panel to the Colorduino, I applied 5v power to the board and was presented with the demo sketch thats installed by default on the onboard ATmega CPU. This runs through a variety of patterns as seen in this video. Please note the flickering is just on the video, the display is rock solid and very very bright As mentioned i. Tead provide the demo sketch on their site to tinker with. Its nicely set out and commented so you can easily see what each bit does. There are functions to draw pixels, print text or fill the screen with a certain colour. If you are a beginner its quite satsifying and it wont take long before you are tweaking the arrays of pixel data to draw your own pictures. I also discovered Lincomatics rather excellent blog. He has re worked the demo code into a library making it even easier to use. Get it here as a download. After youve tweaked the demo sketch youll want to upload it to the Colorduino to see your changes. There is no USB port on the Colorduino, so you cant just plug it into a PC like an Arduino, however if you have a spare Arduino lying around there is a trick you can do. Simply remove the ATmega chip from your Arduino and connect the Colorduino to the Arduino board as follows. Arduino RX to Colorduino RXArduino TX to Colorduino TXArduino Reset to Colorduino DTRArduino 5v and GND to Colorduino 5v and GND. This essentially turns the Arduino into USB to serial programmer. Then you can upload your sketch to the Colorduino using the Arduino software as normal. Alternatively you could also use something like a USBtiny. ISP, as the Colorduino has an ICSP header port too. As i. Tead use the DM1. LED controller to do the hard work of driving the display, there are plenty of resources left over on the onboard ATmega CPU for the taking. My demo board came with an ATmega 1. I understand the final boards will come witn a 3. K RAM to play with. The demo code only takes up 4. K and could easily be slimmed down. I had a go at adding I2. C support, and managed to run the rather cool Plasma Demo over I2. C, sending data from an Arduino acting as master see video below. The code is very basic but if you want to try it its on now up on Google code here. The ability to use I2. C really expands the use of boards like Colorduino and Rainbowduino. Although it doesnt make so much use of the onboard resources, you are no longer limited by the onboard storage and processing of the ATmega CPU. For example I have an SD shield for my Arduino  and was able to send graphics from a 1 Gig SD card over I2. C to the Colorduino. You could also be clever and use something like Processing to stream live data from a laptop. Of course all this really comes into its own when you combine a row of Colorduinos all plugged together. Mini video wall anyone Overall impressions. How To Enable Drivers In Windows 10. As a prototype the board is a little rough round the edges which is to be expected. The extra colour depth and 6 bit adjustment features the DM1. CPU resources for other tasks. All in all this makes the Colordiono stand out as an attractive alternative to the Rainbowduino.
