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.

Firmware loaded OK. MMBasic running OK. GUI calbrate OK. Picomite demo OK. Typing in word 'files' brings up message: 'SD card not found'. I have checked for hardware problems (connections, shorts, wrong earths) none found. The card checks OK in another machine. Mauri |

As thwill has hinted at, you have to tell MMBASIC that there is an SD card connected. By default, MMBASIC will assume that it does NOT have an SD card. From the PicoMite manual, page 38: "SD Card Support" Smoke makes things work. When the smoke gets out, it stops! |

The OPTIONs are as suggested by Admin Group except for SDCard: OPTION SDCARD GP21. In Silicon Chip design GP21 the pin used for SD Card. PG22 is used for Infrared input. |

If, as implied, you are using the SC design then most of us have no access to the design which make it difficult to help. Normally, if the connections and options are correct, issues with SD are solved with improved power supply and/or decoupling the SD supply from the main supply as in my designs. |
