ESP32-S3 multiple SPI buses - SPI, VSPI, HSPI, FSPI, WTF…!? More precisely, we need GPIO 11 (FSPID), GPIO 12 (FSPICLK) and GPIO 13 (FSPIQ) To decipher the cryptic naming, especially FSPI D and FSPI Q (FSPI CLK at least makes sense), we can again refer to the datasheet and discover that FSPID is the data in pin, which is the MOSI pin
ESP32S3 FSPIWP\FSPIDQS pin and how do you specify it ? I was trying some code for a LoRa device and not knowing what the FSPIW\FSPIDQS (GPIO14) pin was on the pinout I used it for the LoRa devices TX_Enable pin This caused problems A transmit program would start, the USB port would disconnect and the program would run at 1 3rd normal speed Clearly the FSPIW\FSPIDQS pin was interfering in some way It seems like its an ESP32S3 do not use pin
ESP32-S3 SPI pins? - Electrical Engineering Stack Exchange Tried Googling for pin reference but after reading so many blogs and data-sheets got more confused as some say "you can use any GPIO for SPI", "FSPID is MOSI, FSPIQ is MISO, etc"
