Could you provide correct GPIO pin configuration for CS, DC, RST, MOSI, and SCLK on this board?

I've worked with the T-Dongle S3 before, and the ST7735 display is typically wired through SPI. On most versions of this board, the pins are usually mapped as MOSI to GPIO35, SCLK to GPIO36, CS to GPIO34, DC to GPIO33, and RST to GPIO37. That said, pin layouts can sometimes change depending on the manufacturer or board revision, so it’s worth checking the official schematic if you run into issues. If the screen isn’t responding, it might also help to confirm that the SPI settings and pin assignments in your code match the hardware. I’ve seen some people even use this small display for simple UI projects or mini game stats dashboards inspired by games like Retro Bowl, which is a fun, creative use for this board.
