Coding for test

On Thursday and Friday, I spend some times coding the threads of the test PCB. I first debug and check if everything was ok for our thread that will read the state of all the box via the hall effect sensor. I used a logic analyser to check if everything was fine. I checked that the four pins that will be used for the multiplexer will not change until the end of the sending of an I2C message. Then I code a thread that initializes all the H-bridge by putting them at the 0 state.

I also realize that I have not seen a mistake in our scheme. We have put a resistor that will limit the current at 0.5A but we need a current of 1.5/2A, so we will need to unsolder these resistors.

Now, I will begin to implement a code that will print an image via the H-bridge.
