ST7789 parallel?

[foxt]

Hi, I was looking to see if I could try TinyGo on a Pimoroni Tufty2040, I see there's already a board configuration for it, but from what I can see the existing ST7789 only supports SPI mode whereas on the Tufty the LCD is connected in parallel mode? Is there any plans to support ST7789 in parallel mode? Thanks in advance

Is the LCD only available in parallel mode, or can you also control it using SPI?
The RP2040 is often fast enough to control the display over SPI. So if that works, you can try that first.

I'm not aware of any ST7789 parallel support in TinyGo, but you can take a look at the ILI9341 for a driver that does support this.

Hello @foxt I think what you need is https://github.com/tinygo-org/pio/tree/main/rp2-pio/examples/tufty

@deadprogram yeah thanks! that seems to be what i was looking for, however i couldn't seem to get it working. no errors on serial console, and the backlight turned on but the lcd was either just blank or occasionally garbled data
