WT32-SC01 - Only shows a white screen about esp32-tux HOT 16 CLOSED

@ericjmonson
Can you try flashing your device from the following URL for testing?
https://tux.sukesh.me

Also, if you have compiled for Plus version, please make sure to delete the build folder and start fresh since the target device settings might be wrong.
WT32-SC01 uses ESP32
WT32-SC01 Plus uses ESP32-S3

I would suggest, you use a released version of ESP-IDF since the main branch of the repo is a moving target and is expected to have breaking changes.

That web installer is pretty slick. Unfortunately, though, I still only see a white screen after flashing with your version. I happen to have a handful of the WT32-SC01 (original ... not plus) devices, so I tried it on two different models. Both end up with just a white screen after flashing.

As for building, I was worried about artifacts lying around. I did a completely fresh clone of the git repo, made sure that esp32 was set as the build target, followed the video for setting up the partitions and selecting the device. I end up with a white screen when I compile on my own.

I will test and revert.

Will check and update tomorrow. Sorry for the delay.

Update: @ericjmonson & @gjm19761

I just flashed my WT32-SC01 device with firmware from https://tux.sukesh.me
And it works perfectly fine as expected.

So possible reasons for you not working

• Wrong device?
• Device specs have changed (like display controller)
• Not genuine device?

Can't think of any other reason :(

If you haven't checked yet, please flash from this website using 1st option and check.

You can check with this older sample without LVGL using the code in the README.

Sorry for the sideways video ... but so you can see it happening in action:
https://www.youtube.com/watch?v=91B7wnW03ww

I definately picked the correct one. I also have a wt32-sc01-v3.2 (as you'll see from the video).

I compiled and flashed the arduino version above (https://github.com/sukesh-ak/LVGL8-WT32-SC01-Arduino#touch-and-draw-sample-without-lvgl). When it starts up, the screen flashes white then black a number of times, then eventually just turns black.

Can you check this from Arduino?
Please install LovyanGFX library and select ESP32 Dev Module for devices.

Yeah ... as I mentioned above, I did install LovyanGFS in the Ardunio IDE and selected ESP32 Dev as the board. That's where I get the black and white flashes followed by a black screen.

ok try the above snippet I just created to narrow down the issue.

Flashing the above application, I end up with a white screen.

Well ... good news. Been playing around with this today. Was able to get it working with my version of the boards. Had to change one line:
main/devices/conf_WT32SCO1.h
Line 81: cfg.freq_write = 80000000; // SPI clock on transmission (up to 80MHz, rounded to 80MHz divided by integer)
Changed to: cfg.freq_write = 40000000;

Now its all working. Not sure if there is more noise on the line making the SPI bus unstable at that clock speed, or why I had to drop the SPI clock speed.

Can confirm this also fixed mine, will this be added to the web installer as suspect theres been a revision of the sc01

Glad you guys got it sorted it out :)
