Using PROGMEM with U8g2.drawXBM

redfirebrooks · March 14, 2018, 9:48pm

Hello,
I started to play with a ssd1306 and thought it could be funny to play on it some animations.
Because XMBs use a lot of memory pictures arrays should go in PROGMEM.
I have followed a example found on google but I have a strange result displayed.
What am I missing ?

#include <U8g2lib.h>
#include <avr/pgmspace.h>

U8G2_SSD1306_128X64_NONAME_1_HW_I2C u8g2(U8G2_R0, 5, 4);  // SW SPI Com: SCK = 4, MOSI = 5, CS = 6, A0 = 7

The U8G2 library doesn't support the reading of flash memory directly. You have to get a copy of your graphics to RAM first and then provide a pointer to that memory to the U8G2 lib. You can read the flash memory with the pgm_read_byte() function.

Actually it is working using “u8g2.drawXBMP”. Working like a charm now
