1.44" inch Serial 128x128 SPI Full Color ST7735S tft

I have this 1.44" inch Serial 128x128 SPI Full Color TFT LCD Display with following specs:

• ST7735S

• SPI interface

Pins:

• 3V3
• GND
• SDI
• SCL
• CS
• RST
• RS
• BLK

but the docs at https://luma-lcd.readthedocs.io/en/latest/install.html#st7735 mention 16 pins.

Did I get an incompatible device because I'm confused how to hook it up.

Ha! I got one as well, but haven't had the chance to connect it up yet. It should be compatible. The pinouts detailed in the docs are for the device I already had which has a built in microSD card reader.

Looking at the listing it should be straightforward-ish to map to the correct RPi pins.

There will need to be a small fix to the st7735 device to accept width/height params (I took the decision, wrongly as it turns out, to hardcode to 160x128)

One of my ssd13-something screens started smoking the other day so I'll wait for a confirmation ;)

awesome, thanks

@thijstriemstra there should be a config/st7735_128x128.conf in the examples repo which is suitable.
