I'm currently working on a RPi project to control an RC car via my phone, and I am having difficulty setting up my ESC. Based on research I have done online, I need to first calibrate the ESC by sending a series of high and low signals, and I'm having trouble achieving this. My ESC is connected to the Pi through a PCA9685 board, and this is what I am using to send PWM signals to the ESC.
To calibrate the ESC, how do I find the values that I need to send for these high and low PWMs? The ESC I am using can be found here
Once I have found these values, what is the series of signals that I need to be sending to properly calibrate my ESC?
