In this tutorial, I will show you how to program your Seeeduino Film as well as connect the Seeeduino Motion Frame to the Seeeduino Film.
Tools and Materials:
Seeeduino Motion Frame
Soldering Iron and Solder
Jumper Wires/5-pin Header
Programmer (3.3V FTDI Breakout1 or 3.3V FTDI Breakout2 or UartSBee)
Step 1: Pin Outs and Mistakes to Avoid
We want to solder to the Programming Port labeled in the first picture. The pin outs are order from left to right are: DTR, GND, TX, RX, and VCC. I first used standard male breakaway headers. These are usually great for prototyping, especially with a breadboard. The problem I found was that if you are not careful when removing the Seeeduino Film from the breadboard, you can easily rip the Film. Which is exactly what I did.
Step 2: Jumper Wires
Step 3: Programming Film
Alternatively, you could use the UartSBee, also made by the Seeeduino crew. This is also an FTDI breakout with two exta features: it serves as an XBee programmer and breakout with female sockets, and you can set the output voltage with a flick of the switch (3.3V and 5V). This board correctly reflects the pin outs of the Seeeduino Film. If you use the UartSBee make sure to set the output voltage to 3.3V.
I have used 3.3V Sparkfun FTDI breakouts and the UartSBee to program my Film boards and found no difference. First, insert your wires into your breadboard, and double- or even triple-check that you know which pins map. Next, line up your programmer and insert it into the breadboard. After powering your programmer, hit the sleep button on the film and the Film's LED should blink! Your film is now ready to be programmed! Load up Arduino and set Board type to Arduino Pro or Pro Mini (3.3V, 8MHz) w/ATmega168.
Step 4: Connecting FRAMEs
To connect the Frame to the Film or the Film to the Frame, first unlock the socket. The black plastic tab actually pulls out just a little bit. See Pics. Next, simply insert the Golden Finger of one of the Seeeduino products into the Socket of the other. Finally, push the black tab back to lock. Remember, treat the Film and Frame gently so as not to damage them.
Seeeduino is Arduino-compatible and the Seeeduino team has written several Arduino-based demos that interface with the Motion Frame. They can be downloaded here. Remember: when programming, use only 3.3V programmers and set the board type to Arduino Pro or Pro Mini (3.3V, 8MHz) w/ATmega168.
