 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. |

I was considering it as a candidate for running Annex32 RDS. Of course, I'd prefer MMBasic but that's not available for it. :) Aliexpress link Only 3 available GPIO, but that's fine for I2C expansion. It might be expandable via bluetooth or BLE too, and has wi-fi connection. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Nice price, having 1 hour of fun and it is payed :)) I doubt that it is suitable. They left out any info about the display. But with VSC and C++ it should be fun. LVGL? edit Edited 2025-11-26 20:49 by dddns |

There seem to be two different displays used (there are variations in boards). Earlier ones used the ILI9341, later ones use the ST7789. Both are on SPI. I think the touch controller is the XPT2046 on both. The display seems to be 8 colours by default (probably to save RAM). Yep, LVGL. :) Linky It seems to be very popular in the "maker" community. There's been a lot of projects done on it - because it's so cheap. My favorite is a bluetooth-connected MIDI controller! I might just grab a couple and have a bit of a play.

Lots of CYD posts on the Annex forum. It's working, but can't vouch for any specific Aliex vendor: https://www.cicciocb.com/forum/search.php?keywords=cyd PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Thanks. :) (Although it tells me that I'm not allowed to use the search system - probably because I'm not a forum member). I'll try a couple anyway. If I can't get it to work I'll have to load python. :) I tried the Arduino IDE again tonight, with an old nano that I dug out of a drawer. Nope, I still don't like the system at all. .

For instance: CYD 1 ESP32-P4 6x4 CYD 1024 X 600 display board: CYD 2 Join the forum. Less active than here, but questions always get answered. Especially if you want to try LGVL (I haven't). PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

I've just joined, awaiting admin approval before they'll let me see anything though. I've ordered a couple of boards now (they were on special offer). I'll find out how bad they are in a couple of weeks. :) They are the 2.8in version with the USB-C as well as the micro USB. I'm especially interested to see if I can make a bluetooth link to, say, a RP2040-Zero via an HC-05. It would open up wireless expansion quite nicely without needing wi-fi. That's a bit of a dream at the moment though! At any rate, they are an interesting device to use as a monitor for wi-fi, BT, i2c or COM connections without needing a second Pico and display.
