Hello,
I am a beginner who wants to control three DC motors using a dual VNH5019 motor driver shield and a single VNH5019 motor driver with UNO R3.
I wanted to edit the Arduino library for third motor and assigned pin numbers for it. Unfortunately, it did not work. As I do not know much about the MCU, I guessed that the following part might be changed:
#if defined(__AVR_ATmega168__)|| defined(__AVR_ATmega328P__) || defined(__AVR_ATmega32U4__)
OCR1B = speed;
#else
I looked at data sheet of ATmega328, but I did not understand about how OCR1A and OCR1B related to controlling the speed. I hope anyone can help me to get through this… thanks in advance!
P.S I’m not a native english speaker, excuse my grammar!
