Ladyada discusses newly arrived 3.5" TFT capacitive touch screens & their ease of testing via EYESPI. She explores unique RGB TFT samples & an ESP32-S3 board's complexities. Additionally, she delves into DIP chip clips, handy tools for component probing, sparking a hunt on DigiKey.

ESP32-S3 moon phase clock test on 2.1" round TFT display 🌜🌚🖥️

Now that we have somewhat-kinda-sorta working support for RGB TFT displays on the ESP32-S3 - shout out to Jepler, who is doing the hard work over in this PR https://github.com/adafruit/circuitpython/pull/8351 - its time to test it with wifi too! That's right, the S3 can do wifi and these big displays at once, and CircuitPython is a beautiful framework for it since its so fast to iterate. This code snippet is based on PaintYourDragon's moon clock code here https://learn.adafruit.com/moon-phase-clock-for-adafruit-matrixportal but pared down for testing. We get the geolocation from IP, then look up the moon phase. Currently we just hardcoded it to display today's phase, but the next step is generating ~28 different phase images, and we'll display the one for the current evening as the API informs us.

Hello my baby, hello my honey, hello my ESP32-S3 TFT Friend… 🔌🖥️🎉

CircuitPythonista Jepler has been hard at work getting full framebuffer support for RGB TFT displays into CircuitPython https://github.com/adafruit/circuitpython/pull/8351 - which means we can see the REPL on a display as large as this 720x720 4" square TFT! as we type into USB the text mirrors immediately, and we can also use any displayio https://learn.adafruit.com/circuitpython-display-support-using-displayio function or library. Here, we're using 'gifio' to display a simple animated gif, which works nicely!

It's 10pm Late night display init code hacking 👁️👩‍💻🌙

It's 10pm. Do you know where your engineers are? We're digging through our pile of funky cool-shaped displays, starting with the round ones first! These displays have 18-bit RGB, 6 bits each or R G and B, plus the V and H sync, data enable, pixel clock, etc. Unlike some basic rectangular displays, these ones need configuration over SPI. So we spent some of that late-night-hacking time to get the init code 'ported' over to the Arduino library we use:

..next we converted an eyeball graphic from BMP to raw 565 bitmap with https://github.com/adafruit/Adafruit_Media_Converters and uploaded it to our ESP32-S3 LCD Eval board
