I am a beginner of VHDL, I need to build a project of obstacle detection car by using ZedBoard.
I would like to use RCWL-1601 to detect whether there is obstacle of the car and collect the distance value from the car to the obstacle.
The car should have 3 wheel, the first is used to control the direction and the others wheels are used to go forwar.
The algorithm of the car is simple but the problem is I don’t know how to drive the servo for turn direction and go forward.
From my knowledge in previous embedded system courses, I need to use pwm to control the servo but I have idea how to do it on FPGA.
