esp8266 issue with SH1122 OLED
Posted: Wed Jan 26, 2022 11:42 amHi i try to use esp8266 nodemcu with dcs bios i tested OLED and its work correctly with graphic test from U8g2 templates when i use this code its work correctly with mega 2560 but when switching to esp8266 its give me some strange artefacts on OLED
ESP8266 glitch
Mega correct display
im quite noob with arduino so maybe some one can pinpoint issue thanks
