Today's win. Getting the Zero to talk to an ILI9341. PDQ GFX library has the pins defaulted to pins that aren't on the headers of the RP2040 so I had to find the pin #defines and change them.
Now we're talking to:
1. The ILI9341 colour TFT
2. Encoder
3. SD Card
Next - RTC Module
#RP2040
#Arduino

I tweaked the waveform I use to drive the 8-bit parallel ILI9341 LCD. Now it's gone from fast to absurdly fast. The 320x240 GIF is playing at 220FPS.

Bought 40 2.2” 320x240 TFT displays for class. They were cheap, well supported by CircuitPython, & as TFT they can be left on without burn-in. Will have to put together some new displayio lessons. Will be fun to show same base code running across displays including HUB75s github.com/gallaugher/i...

Zeller MA paired two of our XIAO ESP32-C5 boards in a dual-MCU build: one runs esp-at as a dedicated 5GHz Wi-Fi module, the other drives an ILI9341 SPI display as the main controller. A smart split that keeps the controller responsive.

I haven’t written code since the 90s but this old retiree has really enjoyed playing with Pico pi’s and #Micropython.
Only took a few hours to get a gps module working with a TFT display. Still can’t install the LVGL library into Thonny on my Mac though😡. But the ili9341 library works.

It does support hardware SPI, though it's max frequency is slightly slower than the ESP32 from memory (60ish vs 80ish MHz?). Both are faster than the ILI9341 can handle though (7ish MHz according to the datasheet, typically mid-20's is fine).

“The hardware itself is very modest: a dual-core ESP32-S3 clocked at 240 MHz and a 320×240 pixel ILI9341 SPI TFT display using 16-bit RGB565 color”
…ok dude now I’m expecting Quake 2. 240mhz is nothing to sniff at.

Working on running TFT_eSPI on the ch32v003 with the ch32v003fun framework.
I’m writing a basic API to use the init functions from TFT_eSPI with plain C. This ILI9341 and an ST7796S are working so far 😀

No idea if anyone finds this useful, especially since I need to fold in a few more controllers, but it supports a few as of now:
gc9a01
ili9341
ssd1351
st7735
st7789
st7796
All you need to provide is a few functions to set/clear CS,DC,RST and write to SPI.
