pwm on SparkFun Thing Plus

Post by ttadam » Wed Feb 09, 2022 1:38 pm

Helllo there,

I came across a really weird bug. I think it has something to do using not the correct fw?
I would like to controll a servo (a linear actuator to be specific)
So I have multiple esp32 boards. One is generic aliexpress esp32-wroom-32, other is a fancier SparkFun Thing Plus. I have multiple of both boards, tested all of them.
On the aliexpress boards the PWM works as intended. But on the sparkfuns there is no signal coming out of it. For high and low okay, but if I want to use pwm, there is no signal coming out. (I am using a logic analyzer, to test the signals.) Everything is the same, same cable, same code.
Anyone else experienced something similar? What firmware should I install on my sparkfun board?

Thanks in advance,

I found the issue, there is a known bug for the pwm. I installed the newest Nightly builds, that solved it.
