at v3.0.21.1a there is a problem with the OLED display mod. After selecting the file (by push-button or automatically), there are errors in the first line. Can you correct that please?

And the blinking second LED is annoying with scrolling text...
(Note each register writing use now a 6 bytes i2c "burst" write sequence, hope that the mod can support this. Also : the bus frequency was reduced to 85kbits/s).
For the led, unfortunately there is no choice : disable the scrolling to avoid the blinking. this led is connected on the i2c line, I really don't know why the hardware was designed like this...
