Title: Problem compatibility between EVB Rev K - Rev K1
Post by: Brice on March 17, 2025, 12:49:29 PM
Hello everyone,
I use an olimex REVB Rev K board with the screen supplied by olimex (MOD-LCD2.8RTP) with an ILI9341V chip for the LCD (SPI) and  NS2009 (I2C 0x48) for RTP . When I upload the same program to the Rev K1, nothing appears on the screen. However, I can't see any major difference between the two versions. Do you have any idea what could be causing the problem?

As far as I can see only the reset IC was changed. Shouldn't be a problem but might require slightly more power.

1. Is the same MOD-LCD2.8RTP that you use with both revisions?

2. How do you power the setup?
