Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

RP2040+ESP32+ST7789V=LilyGo T-PicoC3 ..can be purchased on Aliexpress for $13.58 with free shipping... Just..woaww! The ST7789 is supported by PicoMite, but can anybody tell me if the ST7789-V is supported too? (if any differences exist). I would like to be sure MMBasic can run on it before sending some bucks oversea...Thank you! LilyGo T-PicoC3 ST7789V |

Looks to me like the ESP32 is driving the display rather than the Pico |

Might be an idea to find, read and understand all the documentation before even considering this board. Remember, you are unlikely to have meaningful manufacturer's support unless you are fluent in Chinese. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

The schematic indicates that the display is on Pico pins GPIO 0-5. Visit Vegipete's *Mite Library for cool programs. |

One site I was looking at suggests that the V version of the display has a CS pin, the non-V version doesn't. However, that's not guaranteed to be correct. MMBasic needs the CS pin for its driver. https://community.home-assistant.io/t/standalone-st7789-tft-not-working-with-esphome/230244/3 Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

I'm unsure about the USB (for console) but may be from the ESP32. Overall, sounds like maybe needs some changes to MMBasic itself. John |
