I have no idea how to do this or what they are talking about.
Finally, if you're sure no one else had the issue, it's probably you.
Board name WEMOS LOLIN32.
Must hold down button near edge to begin program.
This ESP32 board requires the SSD1306 libraries to communicate with the OLED display.
On this board the I2C communication pins to the OLED display are pin5 (SDA) and pin4 (SCL), so make sure to change the pins in the initialization: SSD1306 display(0x3c, 5, 4)
Adafruit HUZZAH32 – ESP32 Feather Board
Don't need to hold anything low on the Feather.
- I2C Connections:
- SCL 22
- SDA 23
Heltec WiFi LORA 32 V1 – ESP32 with OLED and LORA Board
To program you need to hold button labeled PRG near coil antenna.
- I2C Connections:
- SCL 22
- SDA 21
I2C address is 0x76 or 0x77 if you cut the trace between the left two pads and add a jumper to the right two pads.
Sometimes to program ESP32 via serial you must keep GPIO0 LOW during the programming process.
