I'm trying, but I could not do it, I need your help, exercise 13.7.6 FPGA book Prototyping by VHDL Examples: Xilinx MicroBlaze MCS SoC, 2nd Edition, It says deduct controller routines (are in gpio_core.h and gpio_core.cpp) for the servomotor treated in section 13.6. Write a test program (PWM_LED.cpp) and verify its operation. I am using the servo Tower pro 996r. What I want to do is put a certain angle, 30, 60, or 180 (like when I used arduino or raspberrypi), and the servo is positioned in that particular angle. I leave the datasheet, the driver files from where I must deduct the routines, and an explanation in jpg taken from the book.
