Incorrect pin definition for the LED blink example on the ESP32-S3-DEVKITC-1
Posted: Tue Oct 11, 2022 12:26 pm
Just a heads-up. I recently tried compiling and running the blink example on a ESP32-S3-DEVKITC-1. The LED was not blinking. After some troubleshooting and reviewing the schematics, I found the default project pin assignment in the menuconfig was set to GPIO #48 which is incorrect. It should instead be 38. After making the change, the LED started blinking as expected.
The README.md file should be updated since it has the incorrect information below:
" Some development boards use an addressable LED instead of a regular one. These development boards include:
| Board | LED type | Pin |
| -------------------- | -------------------- | -------------------- |
| ESP32-C3-DevKitC-1 | Addressable | GPIO8 |
| ESP32-C3-DevKitM-1 | Addressable | GPIO8 |
| ESP32-S2-DevKitM-1 | Addressable | GPIO18 |
| ESP32-S2-Saola-1 | Addressable | GPIO18 |
| ESP32-S3-DevKitC-1 | Addressable | GPIO48 |
