I have downloaded the files from https://www.b4x.com/android/forum/threads/radafruitssd1306-oled-displays.68906/#content and also the GFX files. I am using the same display as Erel but with a NodeMCU. I have tried the Clock example and it runs fine without any problems but my program will not compile and I cannot see the error.

Have you tried adding rCore.h to the extra defines. as the message looks similar to when it hasn't read the definitions for Int etc.

Brilliant! That solved the problem. So it was a bug in B4R, I hope Erel can fix this because it drove me mad for two days. Why should the Clock example work and my program not!!

Many thanks.
