ATMega8 based protractor with SSD1306 OLED and LIS3DH accelerometer
ATMega8 based protractor with SSD1306 OLED and LIS3DH accelerometer.
Schematic and PCB made in KiCAD. Firmware project created in Atmel Studio 7. Makefile available.
Known issue - ISP header is flipped, don’t try to connect it to AVRISP with kanda ribbon cable, it’s gonna make a short.
Firmware is working, but some extra features are still WIP (@TODO in main.c)
Display driver made by @tibounise (https://github.com/tibounise/SSD1306-AVR) slightly modified by me to save RAM for framebuffer.
