Hi there. We’re considering the Argon platform for our servos, and I’m wondering how suitable the digital outputs are for generating PWM signals. How quickly can they be toggled / what’s their maximum frequency?
In short, you might wan to check which pins of that STM32 can produce PWM output by timer peripherals. If that doesn’t work, you can use software to drive any GPIO pin.
The optoisolators are quite low speed types, so don’t expect more than few kHz output from them.
