Hi 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
Code: Select all
#include <Arduino.h>
#include <U8g2lib.h>

#include "DcsBios.h"
int count;
//U8G2_SH1122_256X64_F_4W_HW_SPI u8g2(U8G2_R2, /* cs=*/ 10, /* dc=*/ 5, /* reset=*/ 4); // Mega 2560 scl pin52, sda pin
