Wrong font size when replacing 160*128 display with CFAG160128E


New member
When replacing a Varitronix VLGEM1473 display that use the same RAIO RA6963L2NA LCD controller with a CFAG160128E, I get displayed the same characters but in a larger font size of 8 instead of 6. Graphics and text are affected.
Any idea where this might come from ? Which lcd init parameters should I change to make it work right?


Thank you in advance for your ideas.

Solution found,
It was the font selection hardware pins of the controller that were at different levels.
Found it in the RAIO RA6936 datasheet :


I hope this can help someone else.
