While tinkering with Frank's Christmas Bells project I thought a useful addition to MMBasic might be a Port version of the ADC command. That is, reading a Port instead of an analogue input. For Frank's project speed wasn't an issue but for faster data the Do: Loop routine I used would be too slow. Is this feasible and if so is it worthwhile? |

In what way(s) would it differ from the existing Port command & function? John |

Sampling rate. My test with a For / Next loop fluctuated around 60 -70 µS/sample. ADC can sample down to about 2 µS/sample with reliable timing. Edit. ADC Open, n can read 4 channels' but if you want to read a 8 bit bus... It also uses a lot more memory with at least 8 bits per channel versus 1. Edited 2025-11-14 17:54 by phil99 |

@Peter, This is an awesome addition! Without having a PicoMite nearby to try it right now, can you confirm it will work with SPI screens too! If so, then is the turtle’s area/screen-size determined by mm.hres and mm.vres OR is it limited to something else ie 320x240 ? Thanks…. |

@phill, Sorry, I mis-read your message. You where asking about reading a PORT in a faster automatic sequence. Not the reverse. I can only offer PIO. The logic analyzer uses it, but that may be far to complex to be used as a basis for the bells. But the terminal version might be an option, since it contains only the basics. It is published in the PicoMite user manual, appendix F, sample program #3. Volhout Edited 2025-11-14 18:36 by Volhout PicomiteVGA PETSCII ROBOTS |

Bear in mind that the Pico only has one ADC on the chip. The inputs to it are multiplexed. It's impossible to read all the ADC inputs simultaneously as each read takes a finite time. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Thanks for that. That certainly could be adapted to read a parallel bus. |

It worked for me with a 480x320 ILI9488 SPI LCD. All tests ran. I think only two showed results which might be considered anomalous, where plot points outside the screen resolution plotted at the maximum x or y. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Hi Peter, new bug / problem with your latest updated RC12: you fixed IR (now works!) but: play mp3 "name_of_file" does crash the whole picoMiteHDMI (tested version)... my option list is the same as the picture in my above post with the IR bug. I can remember a few iteration ago there was also this play mp3 problem, but you fixed it, now the problem is back. Greetings Daniel |

Version 6.00.03 Print MM.Info(exists "a:/profiles.txt") is giving me a syntax error. The file exists as MM.Info(filesize ...) works. Not tested on a beta or rc as I want a (more or less) stable version for my hotplate temperature controller. :) .

That's what happens if you invent syntax  manual page 85 |

Oddly enough supported by MMB4L which makes me suspect it was supported by the CMM2 but not the PicoMite. Still kicking, Tom MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Should it be Print MM.Info(exists file "a:/profiles.txt") John |

There seems to be a bug in the turtle graphics .... If I run the test program form Peter (earlier in this thread) at test # 10 (cursor tests) subtest "different cursor colors" fails with invisible cursor if the test is repeated. The first run after a reset or cpu restart is ok. There is also an artefact left over after the first cursor is painted. My setup is as follows: PicoMiteHDMI MMBasic USB RP2350B Edition V6.01.00RC12 OPTION SERIAL CONSOLE COM1,GP0,GP1 OPTION FLASH SIZE 16777216 OPTION COLOURCODE ON OPTION KEYBOARD US OPTION PICO OFF OPTION RESOLUTION 640x480 @ 252000KHz OPTION DISPLAY 30, 53 OPTION HDMI PINS 1, 3, 7, 5 OPTION SDCARD GP22, GP6, GP7, GP4 OPTION AUDIO GP26,GP27', ON PWM CHANNEL 5 OPTION MODBUFF ENABLE 192 OPTION PLATFORM OLIMEX USB The effect seems to be independent of the mode setting.

What do you do after each run? ctrl-c or press 0 or what? |
