the pi is still saying no motor controller connected, any troubleshooting i can perform? ive checked voltages, ensured the arduino ide uploaded the motor.ino and the crc.h file successfully, did it twice. all connections look good....
Thank you!
At the risk of stating what should be obvious - tx and rx should be cross-connected. Tx is an output and rx is an input. This is contrary to the i2c bus, where simarly named signals are tied together. So: the tx of the pi goes to the rx of the arduino, and vice versa.
