About this repository
- tools/dtr-toggle.c is what you think it is: it toggle DTR on /dev/ttyUSB0 or whatever the 1st argument is. This reboots reliably my ESP32 module.
Samples for one of my ESP32 modules
Read from a DS3231 RTC and display the time on the OLED
Read from a BH1750 light sensor and display on the OLED
Another ESP32 module: TTGO Eight
A slightly different ESP32 module (TTGO Eight) with a similar OLED with a different controller (SH1106 instead of SSD1306). Also I2C pins are different. Just drawing circles.
