For our next installment, I have a lovely and daring PCB submitted by one of our readers, [Vas]. This is an ESP32-S3 board that also has an onboard round TFT display, very similar to the one we use… ...

First of all, STVA080W-01 is an 800*600 resolution Advanced type serial screen with 4-wire resistive touch panel, brightness up to 900cd/m2, viewing area 162*121.5mm, working temperature -20~70 ...

Using the ESP32’s I2S peripheral in parallel mode makes it possible to shift data out in the correct format to drive the LCD without bit-banging IO pins and using up precious CPU time.
