set_GPIO not working #364

|
Hello everyone, i'm trying to set gpio16 high (3.3V) when the ESP32 is online and running and not in sleep. I hooked a button to switch between sleep and running mode. I would like to do that so that I can switch some button lighting on when the player is on and off when I give a ACTRLS_POWER command via the switch. The only problem I have is that when I set the "set_GPIO" value in the NVS Editor to '16=power' (without the quotes), and then commit and reboot. The software will stay in a boot loop and shows only SqueezeESP32 and it won't boot anymore. I need to reflash the ESP32 and start all over again. Is there someone who can help me with this? Thanks on forehand. |

Pin 16 is a dedicated pin for SPI0 (PSRAM), you cannot use it. Which ESP-32 do you have? because normally on the Wrover this pin is not accessible and is marked "NC". |

Hello Renber78, thanks for the information. This was the problem. That also explains why the ESP came into a bootloop. It al makes sense now. I used another GPIO which isn't used by any internally connected chip and it now works as a charm. Thanks for the help! BTW, I use an ESP32-WROVER-IE dev module which has these pins broke out. |
