anyone managed to write some basic code to initialize and write to a display based on ST7796 with a capacitive touch sensor using GT911. (52pi model ep-0172) I got a nice board with a 480x240. i'm building an irrigation controller. it would either be this display or a 2x40 character ... |

You could use a 3.5" 480x320 SPI ILI9488--considerably better than a 2x40. ~ Edited 2023-11-10 06:46 by lizby PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

most of those are resistive touchscreens... never liked those. The one i found is a capsense. Anyway i'm not stuck to one type of display. Just that i found a nice pcb with this display and a socket for the pico to jumpstart my development. I may go with the character display after all I have 40 outputs so one character per output to show on/off on the second (or fourth line if I use a 4x40) Top line(s) to show instructions like program number, start time , step number, step count , day of week. plenty of space. And they are sunlight readable... most of the tft's cannot be read in sunlight. |

Did you ever get anywhere with this? The 52Pi EP-0172 is a nice looking dev board. |

I'm looking at the GT911 but is is a complete b.....d to drive. Have a look at https://github.com/STMicroelectronics/stm32-gt911/tree/main for how much code seems to be involved |
