Is it possible to use LCDs with ST7735&ST7739 controllers??

#1 Post by JohnW » 17 Nov 2019, 09:25

Hello,

Is it possible to use LCDs with ST7735 or ST7739 with ESP Easy? I have several of them: some with I2C, some with SPI.

Thanks!

I hope to start a plugin (or extend an existing one) for ST7735 (128x128px/128x160px/80x160px) soon (a.o. waiting for hardware from Ali), and I'll investigate if ST7789 (240x240px/320x240px) can also be supported (but often that last resolution is driven by ILI9341 -> Plugin P095).

Edit: ST7739 either doesn't exist or is a display panel only (45 pin connection, won't work on any ESP without support-hardware), so I assume ST7789 is intended
Edit2: Corrected resolutions per chip.
