 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. |

Peter has delivered the latest release version of the PicoMite firmware V6.02.00. This can be downloaded from https://geoffg.net/picomite.html (scroll to the bottom of the page). It includes the updated user manual and additional specialised manuals (see the Extra Documentation folder in the firmware zip). In addition to fixing all reported bugs this version includes many new commands/functions and enhancements including ASTRO for calculating the position of celestial objects, an extended BITSTREAM command for generating precise bitstreams, a driver for HD44780-compatible character LCD displays, a comprehensive system for controlling stepper motors and the command STRUCT which allows for the manipulation of structures.

I was wondering why Peter was so quiet on the release candidate thread: I thought, "Either he's still hatching an improvement or new feature, or he's waiting a few days for bugs to be found before he can fire off version 6.02.00?"  Congratulations and many thanks for the work, Peter! Thanks to you too, Geoff! |

I missed that one in testing. Is it RP2350 only ? "2350 only" was not listed in the user manual. On 2040 I get "unknown command" Volhout Edited 2026-01-25 21:18 by Volhout PicomiteVGA PETSCII ROBOTS |

Super upgrade, Peter. I've been using structures a lot for the indices in my PicoDB database (files which are arrays of structures), and they're very helpful--especially for sorting. A question regarding the warning that drive A: may be erased. That's definitely the case for earlier versions, and I think for at least the first RC. Will that happen with the later RCs?

Yes, for new releases I force a complete flash clear - we have ways... |

 Does anyone else have this problem with MP3 playback from the FM175? It used to work without any problems. It also works when I start playback from the prompt. > option list PicoMiteHDMI MMBasic USB RP2350A Edition V6.02.00 OPTION SERIAL CONSOLE COM2,GP8,GP9 OPTION SYSTEM I2C GP20,GP21 OPTION FLASH SIZE 4194304 OPTION COLOURCODE ON OPTION KEYBOARD GR OPTION RESOLUTION 640x480 @ 315000KHz OPTION SDCARD GP22, GP26, GP27, GP28 OPTION AUDIO GP10,GP11', ON PWM CHANNEL 5 OPTION RTC AUTO ENABLE OPTION MODBUFF ENABLE 192 OPTION PLATFORM HDMIUSB > Matthias |

That does appear to be the case. On the RP2040 there is the new 2 pin Bitstream command that could run a stepper motor in bursts. The amount of memory for the arrays would limit continuous running. If more than one motor I think it would only do one at a time. |

Hi phill, Look in the new user manual, command STEPPER. Look at the new EXTRA DOCUMENTATION folder in the zip. This looks a g-code converter for stepper motors. But this is 2350 only, I think. Volhout Edited 2026-01-26 16:06 by Volhout PicomiteVGA PETSCII ROBOTS |
