Blank screen on ESP32-3248S035 capacitive #61

Got everything to compile and upload, but just a blank screen. Tried changing:

define LV_USE_ST7796 1

in lv_config.h, but seems ineffective. I set the default board with: default_envs = esp32-3248S035C and that part seemed fine.

The preloaded demo worked when powering on the board, so I assume the board itself is OK.

Which project are you using? If it is the https://github.com/rzeldent/esp32-smartdisplay project, it is just a library and has no output. If so, try the https://github.com/rzeldent/esp32-smartdisplay-demo project!

It's the *-demo one. I was able to get some of the provided demos from Sunton to work after realizing that one has to set all #defines as command line switches. I noticed in a note on the CYD support pages you may have hacked your copy of this particular board for a different refresh rate. I also may have to learn how to get a crash dump or some output on my run of your demo. Looks like there might be some info there.

Just got a esp32-8048S043C and your demo worked out-of-the-box on that one. Very nice
