I have an LED on GPIO40 . When I start up the ESP32-S3 in bootloader mode, the LED turns on. If I start up normally, the LED is naturally determined my the code.
I just randomly chose that pin, but I really like the LED feedback and want to do that on another project using an ESP32-S2, but the same ...

Re: ESP32 SPI Flash Communication
I have a SD Card connected to:
#define SPI_MISO 12
#define SPI_MOSI 13
#define SPI_SCK 14
#define SPI_CS 5
... and I couldn't upload if I had my SD Card Inserted and used it in my code. But if I took the SD card out or commented out the use of the SD Card, I could upload again.
I believe it is ...
#define SPI_MISO 12
#define SPI_MOSI 13
#define SPI_SCK 14
#define SPI_CS 5

Re: ESP32-C3 EEPROM.C write NVS storage not work
I got that to work in Arduino, but not in PlatformIO.
My platformio.ini:
My platformio.ini:
Code: Select all
[env:adafruit_qtpy_esp32c3]
platform = espressif32
board = adafruit_qtpy_esp32c3
framework = arduino
board_build.flash_mode = qio
