My project is an internet radio using an ESP32 (Heltec wifi kit 32 with built in 1306 display). The coding has compiled and worked many times in the past with no problems whatsoever. Recompiling that SAME code results in no display on the 1306 screen at all, total blank. Compiling gives no problems, no errors, no warnings. The radio itself works fine … just no display
The code uses the SSD1306.h library. If I upload a simple sketch using the #include <U8x8lib.h> library the display works fine. So the display is functioning.
I can include the code but it is long and there have been no changes. I should also mention that any other sketch I’ve uploaded that uses the SSD1306.h library will not print to the 1306 display. Again total blank.
Was the library itself changed and updated unknown to me? What other possible explanation ??
Thanks for any suggestions you can offer …
