I am working with an stm32 f767zit and I am trying to generate PWM signals to control servos, but they are not generating correctly. I followedd the tutorial from here Deep Blue Embedded and was able to generate the PWM signals just fine on an stm32 f103rb, but I switched to the f767zit because I needed more PWM outputs. I have already looked at the HAL documentation and for both and compared them and as far as I can tell there are not any differences in how the pwm signals should be generated.
I have done several projects with the stm32 boards but I am still sort of a noob. I have looked for many hours for a solution but I can not find one. Sorry if this is actually just something simple and basic that I am missing.
Here are screen shots of the pwm outputs. as you can see the f103rb generates them normally, sguare waves at 50hz and 3.3v peaks. The pwm signals on the f767 are made up of lots of spikes and have peaks at 10mV. Although, they do seem to be generating at the correct pulse length
In my code all I am trying to do is initalize the servos and the set them to a positon. There are 12 servos and they are using timers 1-4. The specific channels and pins can be seen in the Servo configuration code. My main code initializes all of the perifrials and then calls initServos() which calls SERVO_init() for each servo in SERVO_CfgParam. Then my main loop calls SERVO_moveto(). I am only moving one servo in the main code but I have tested every pin that I am using and get the same results.
I used the same meathod and code for controlling 3 servos on my f013rb without any problems. I cannot figure out what difference there is on the f767zit.
