Interesting process. You're going to a lot of trouble to find and fix issues before you ship these out, which your customers appreciate. Do you mind sharing what percentage fail the initial tests, and what the most common problems are?
Out of all the boards I have tested so far (about 55), 4 failed. 3 of them were I2C problems on the screen's touch controller. As these come assembled directly from the manufacturer, I hope I can get a refund. The other one that failed had a bridge on the ESP32, which was just a quick touch up.
The guy with the Swiss accent sent me ;) Your ESP32 TouchDown + LVGL (graphics library) would be a match made in heaven, can't wait for re-stocking.
LVGL, TFT_eSPI, Adafruit GFX, a lot of choices :D
Brilliant! A project in itself, worthy of a detailed video of its own on how it works!
It is really fun to build as well!
Looks great. This would be a nice remote control for Home Assistant around the house.
There are some examples in the /examples folder. And the ESP32 TouchDown is also supported by OpenHASP.
I enjoyed seeing your test rig and the whole process
Great! How many have failed out of your batch?
I had 4 screens fail and one PCB that failed initially but was easily fixed :)

@@DustinWatts Very interesting. Thanks for that!
Would you mind to share test script python, really look for same concept for my project.thanks
Sure. I don’t have it on GitHub but I can share via Discord or mail!
@@DustinWatts seems youtube removed my email id🤔

What are you using the SDcard for?
Atm for nothing. But it is there just in case. Of if people want to create a project that uses an SDcard. For example storing images.
what are the grey lines for on the foam pad in front of you?
The lines are double side tape to keep the foam in it's place... not special purpose :)
@@DustinWatts oh they are on the backside shining through !
@@maicod Exactly, the foam is semi-transparent and the double sided tape is black :)
You’ve made it to the land of cuckoo clocks and chocolate well done, and top of the video too. ;-)
Haha.. It took me a while for me to understand your comment.
@@DustinWatts maybe it's only the brits that when the Swiss get mentioned the first thing we think off is cuckoo clocks.
Nice :)
Thanks! And thanks for the chip recommendations!
