Re: ESP32-S2-Saola-1r voltage, here and there, not 3.29V, but 1.69V

of course... thank you for check... there is my code if you check. if i dimm the 4000K Led's like 4000K P1 and 4000K P2 then flicker 4000K P2 total crazy i have to set both on 255 thats run nearly a little normal on the GPIO then i get also not 3.28V i get maybe 1.48 and he jump from 1.2x to 1.4x Vo...

Re: ESP32-S2-Saola-1r voltage, here and there, not 3.29V, but 1.69V

Overage Voltage, peak on my Multimeter is 3.29 if is normal. That i get if i send a signal to and GPIO normaly and also if i send 255 on my PWM-GPIO. I use 8 PWM Ports. and only on some i get jumping voltage between 1.4x and 1.6x Voltage. The LED's like a flicker then, I read any about the ESP32 Boa...

multiple PWM frequency , channels and ESP32-S2-Saola-1

Hello I can't understand the PWM channels from the ESP32-S2-Saola-1 and I get different frequencies (and also different voltages) on the channels. With the result that the LEDs on certain channels start to flicker. In the code below you can see my channel settings. I think I either chose the channel...

ESP32-S2-Saola-1r voltage, here and there, not 3.29V, but 1.69V

Hello, I'm still relatively new to programming with the ESP's and I'm just wondering about a strange phenomenon that I didn't know from the Arduino. As described above, I have the ESP32-S2-Saola-1 here. But I can't find any documentation where it is described which PIN's only output 1.69V when and w...
