 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. |

Please find attached the first beta release of the Picomite - V5.07.00b0 PicoMiteV5.07.00b0.zip Changes from a48: PIN 42/GP29 now accessible ADC command - see below MEMORY COPY and MEMORY SET commands implemented as per CMM2 Swapping between PWM and PFM no longer causes a restart but is still a permanent option Should now install on a blank Pico RESTORE can now take a variable including numeric for a line number or string for a label Various MM.INFO($) sub functions:- FILESIZE MODIFIED OPTION BREAK OPTION BASE OPTION DEFAULT OPTION EXPLICIT OPTION AUTORUN PIN n LCDPANEL TOUCH DEVICE VERSION VARCNT DISK SIZE FREE SPACE FONTWIDTH HPOS VPOS SDCARD ERRNO ERRMSG BCOLOUR 'returns the current background colour FCOLOUR 'returns the current foreground colour FLASH 'reports which flash slot the program was loaded from if applicable FONT ' returns the number of the currently active font FONT POINTER n 'gives a pointer to the start of font n in memory FONT ADDRESS n 'gives the address of the memory location containing the address of font n New command ADC ADC OPEN freq, n_channels [,interrupt] This allocates up to 4 ADC channels for use GP26, GP27, GP28, and GP29 and sets them to be converted at the specified frequency. The maximum total frequency is 500KHz (e.g. 125KHz if all four channels are to be sampled). If the number of channels is one then it will always be GP26 used, if two then GP26 and GP27 etc. Sampling of multiple channels is sequential (there is only one ADC) The specified pins are locked to the function when ADC OPEN is active' The optional interrupt parameter specifies an interrupt to call when the conversion completes. If not specified then conversion will be blocking ADC FREQUENCY freq This changes the sampling frequency of the ADC conversion without having to close and re-open ADC CLOSE Releases the pins to normal usage ADC START array1!() [,array2!()] [,array3!()] [,array4!()] This starts conversion into the specified arrays. The arrays must be floating point and the same size. The size of the arrays defines the number of conversions. The results are returned as a voltage between 0 and OPTION VCC (defaults to 3.3V). Start can be called repeatedly once the adc is OPEN Test example run with OPTION MEMORY 0,16384 ADC open 1000,4,myint Dim a(2499),b(2499),c(2499), d(2499) Timer =0 ADC start a(),b(),c(),d() Do :Loop Sub myint Print Timer adc close end End Sub Edited 2021-07-18 04:01 by matherp |

WOW!!!! What a goody bag! It must be Christmas! (or maybe not quite...) Thanks, Peter! Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Dear Peter, I was just enjoying my holidays, and now I feel the urge I must check this ADC function ;) Thank you very much for implementing it. I will check it out as soon as we get back from the camping site..... Here is nothing, except my mobile phone... Volhout. PicomiteVGA PETSCII ROBOTS |

Very nice, thank you. I hate to ask, but please, please, please when MMBasic returns to the prompt on the Pico could you: 1. Restore the cursor if it has been hidden, i.e. the equivalent of Print Chr$(27) + "[?25l" - having to keep typing this in manually is driving me potty. 2. And less important restore the console foreground colour to the default/white. Also it appears that you have implemented Mm.Info(FONTWIDTH), but no Mm.Info(FONTHEIGHT) ?

What is hiding it? Nothing I do AFAIK |

| thwill Guru Joined: 16/09/2019 Location: United KingdomPosts: 3833 |
The user program, in this particular case "Yellow River Kingdom" but if you break out of the program to the command prompt then it isn't being restored - unlike on the CMM2 for example. It's not even automatically restored if you go into the EDITor. I think this is a usability issue, perhaps there is a downside of restoring it, but if there is then please illuminate me.

Sorry, but no other embedded version of MMBasic "restores" the cursor or makes any changes based on what a user may or may not have done. This is not a CMM2. It is up to the user program to have a graceful exit as there is no way the firmware can know what you may or may not have changed. |

 This is proving to be an awkward platform to develop on without the crutch of MMEdit. Would having the EDITor automatically restore the cursor spoil the purity of your vision ? Any chance of some user programmable function keys to mitigate the problem ? Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

MMedit works fine with the PicoMite. Search on the forum for MMEDIT PICO (all) for Jim's update |

I'm sure it does, and I'm sure it's wonderful, and in the early days I even gave Jim some beer money to support it. But some of us aren't devoted to using Windows (or x86 Linux that can support it through Wine) and I thought one of the selling points and promises of the 'mite ecosystem was the ability to develop on the devices themselves without reliance on the vendor IDE ... which MMEdit is in practice, if not in name.

One more, I can workaround it if it was intended, but perhaps it's just an omission: > cls Error : Display not configured Would be more "friendly" and CMM2 compatible if it cleared the console and silently ignored the LCD display if it was not configured.

CLS is a graphics command it only works on an attached display |
||||
| Volhout Guru Joined: 05/03/2018 Location: NetherlandsPosts: 3496 |
Honestly, I do stumble into the CLS trap often. A terminal screen full of debug results, cls.... oh yeah nothing. I often develop the mite as headless devices, where the terminal is the only screen. Many terminal programs have a menu to clear the screen, in the old msdos world you could key <ctrl>L , but I have not found yet what key to use in putty, teraterm, gfxterm, gterm, minicom. Is ther something generic? Edited 2021-07-18 22:46 by Volhout PicomiteVGA PETSCII ROBOTS |

It is very important in an embedded device that console output and graphics output are separate. I don't know what happens in the TinyUSB stack if you keep sending output to it when there is no connection - does it eventually lock up? use up memory? or what? So for the Picomite graphics commands (including CLS) are separate from console I/O and a running program will create no console I/O unless specifically coded to do so in the same way that it won't generate graphics unless coded to do so. If you set up autorun there is no console I/O in the boot sequence, the code just starts running. Then it is up to the programmer to use the I/O depending on the specifics of his/her application and environment. To clear a connected console just use the standard escape sequence esc[2J e.g. print chr$(27)+"[2J" then print chr$(27)+"[H" to home the cursor |

What is the command to move a servo on, say, pin 25 (GP19)? PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |
