Closed zhongluqiang closed 1 year ago

zhongluqiang commented 3 years ago

https://github.com/espressif/esp-dev-kits/blob/master/esp32-s2-kaluga-1/components/lcd/lcd.c#L269

bug code:

/* Memory access contorl, MX=MY=0, MV=1, ML=0, BGR=1, MH=0 */
lcd_write_cmd(0x36);
lcd_write_byte(0b11000000);

fixed:

/* Memory access contorl, MX=MY=0, MV=1, ML=0, BGR=1, MH=0 */
lcd_write_cmd(0x36);
lcd_write_byte(0x28);

The fix is ported from V4.2 and has been tested on a ESP32-S2-Kaluga-1 Kit v1.3 demo board by examples/lcd demo.
