Generating PWM

Andrei13 — Sun, 02 Apr 2023 14:32:39 GMT

Hi! I am using FRDM KE16Z and i have sdk 2.13. I setted up the FTM driver for generating pwm on FTM0 ch0, ch1, ch2, ch3. I put a wire on pin no 23, wich is PTC0 and i see nothing on the osciloscope. The other function in the photo is for updating the pwm dutycycle. In main is just called the init function and in while(1) part i just updated the pwm dutycycle and added a delay after.

I also added photos with pin and peripherals tools.

TY!

Forgot to add this photo from pins. One is with label and identifier bc i tried to see if that s the problem, but it isn t.

I changed the order of functions in init function, but he output is visible on the blue led, not on the pins. Why? TY!

I fixed it. If you use the PTC pin it s ok, the pwm output is on the pin, but if you use PTD the pwm output is on the led.
