LCD issues with BOOSTXL-EDUMKII dev board

Chris Last

Other Parts Discussed in Thread: ENERGIA

I recently bought the Educational Booster pack MkII and I can get all the example sketches in Energia working apart from the LCD.

I have tried all the Energia EduBPMKII_Screen examples and even tried writing my own drivers from the datasheet. I am using the booster pack with a Tiva C TM4C123GXL MCU and all I ever see with any sketch including the LCD sketches is the backlight on the LCD.

I am beginning to doubt whether the LCD controller is working correctly. The hardware SPI on the TM4C is definitely OK as I have previously used SSI0 to interface with my Nokia 5510 LCD.

I am using Energia Windows: Binary release version 1.6.10E18 (8/11/2016)

Is there anything else I can try before getting a replacement board?

Thanks,

Chris

Hello Chris,

This forum post can be better addressed by the Energia support here: forum.43oh.com/.../

Probably more of a hardware compatibility issue actually but the Energia community did provide the help !

:

The TM4C board connecting my EDUMKII accelerometer output to my EDUMKII LCD MOSI seems to be the problem.

It would be nice if https://dev.ti.com/bpchecker/ thought this was important enough to mention in the notes section in the booster pack compatibility checker rather than "Selected combination is Fully Compatible!"

Hello Chris,

Thanks for posting the resolution here. I will give this feedback to the BoosterPack Checker team.
