Type issue with DisplayUI font: char to uint8_t

[michelep]

In file DisplayUI.h, line 159, I had to change const char DejaVu_Sans_Mono_12[] PROGMEM = { to const uint8_t DejaVu_Sans_Mono_12[] PROGMEM = { to avoid compliation error:

invalid conversion from 'const char*' to 'const uint8_t* {aka const unsigned char*}' [-fpermissive]

Cheers !

Same for me, it started to happen after I accepted to update an Adafruit lib in the library manager.

Confirmed by enabling compile log and seeing this:

Multiple libraries were found for "SH1106Wire.h"
 Used: ~/Arduino/libraries/ESP8266_and_ESP32_Oled_Driver_for_SSD1306_display

Applying the same solution makes the error go away and does not seem to affect the UI.

Weird, those are the default types when generating a font and using the library. Does it fix it when you change it from const char to unsinged const char?

commit 14b99ef should have temporarily fixed that

closing this issue

@vuong244 the fix is in the first comment of this issue, otherwise delete and reinstall the SDK for esp8266deauther from the boards manager.
