Revision as of 04:26, 29 October 2021
I got some esp32-c3-devkitC-02
from the hardware schematic i seethe RGB LED is SK68XXMINI-HS
I used adafruit neopixel library to drive this RGB LED. it's one wire or i2c or something. Pin 8
talk to it via I2C
damn trying to get the boot flashed.
this is what I'm going on now:
https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html
board manager extras:
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json
old config:
https://dl.espressif.com/dl/package_esp32_index.json, http://arduino.esp8266.com/stable/package_esp8266com_index.json
This page has some particulars:

Error creating thumbnail: File with dimensions greater than 12.5 MP
so which pinds are for I2C SDA/SCL ?
Lots of conflicting docs.
I forced the issue like this:
void setup() { Wire.setPins(sda_pin, scl_pin); Wire.begin(); ... }
