Hello Jack, I sympathise with the difficulty you are experiencing - I'm a hobbyist and found the workshops indispensable. It's a shame TI are not maintaining the workshops. This entire thread could have been avoided if they did. Are you sure the file from the workshop is called "Kentec320x240x16_ssd2119_ spi .c"? I had a look at the workshop for the 123 and the file in Lab 10 is for the older display with a parallel interface, as I suspected. It is called "Kentec320x240x16_ssd2119_ 8bit .c" and the comment at the beginning of the file says "this version is for the 8080-8bit interface". I recall getting the same compiler warning when I was starting out - I think it's because you have been loading projects from the (not updated) workshop. Start a fresh project in CCS - the warning will disappear and the grlib_demo should work. It's interesting that you got things working using Energia without removing R9. Did the Energia sketch include touch capability? I've removed the display from the BoosterPack headers on my 129 and reconnected it using cables, and have been working through the display initialisation code (there is a separate initialisation code for touch) to understand what's going on. I'll try it on the 123 soon.
