Hello dear friends,
does any one know how i can have 2 signal with 90 degree phase shift? but i want to use this easy bit pattern to have it and not pwm, just with this bit pattern 00, 01, 11, 10, and also a sleep time for delay, it shouldn't be difficult, i know that i just need one timer, for example TIM16, but i have no idea any more.
here are my codes and so i have 70 degree phase shift, do you have any idea?
Thank you
