This question is very specific to the hardware I'm using. Suggestions are welcome:
I have a pcduino that I want to control a robot with. This means controlling the robot's wheels from commands sent from the algorithm running on pcduino, via motor shields. This is easy with an Arduino+Adafruit motor shield configuration since the motor shield is designed to work with Arduino; there are no hardware issues.
When I try to use the same motor shield with pcduino, the pcduino cannot send commands to the motor shields as (I guess) the chipsets in pcduino and arduino are different. pcduino uses an Allwinner A10 while arduino has the Atmega xxxx chip. Therefore the motor shield does not respond to these commands and errors popup in the Arduino IDE when I try to upload the sketch to pcduino.
Is it possible to make this work without resorting to designing and building a prototype circuit on my own (I'm not EE).
pcDuino IMHO is not intended for native Arduino sketches. May be You should try this approach? https://s3.amazonaws.com/pcduino/User+Guide/pcDuino+arduino+environment.pdf?
Hello, You can always use the same pins marked on the arduino to be used with the pcDuino, but you lose the ability to use it as a shiled, my advice is match as possibly as you can the pins from the pcDuino to the pins of the shield and work around the little differences that arise by customizing the software
It should be possible as long as the pins are matched properly (power-power, data-data, ground,-ground). also check software definition for the pins.
I was actually successfully able to do this. The way I did this was I connected the GPIO PWM pin of pcduino as an output, and connected it to one of the pwm pins of the arduino as input, and the signal that is passed between the two determines which action needs to be taken by the Arduino
