 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. |

Looks like it could be useful but how is it used.... typically? Is it a more efficient approach than something else? I have the feeling that I'm missing-out  |

I'm using it right now in a program with video output so that a user can arbitrarily inject a command, especially for debugging, by typing at the console, e.g., "!test Execute print a$, b$, c$" or "!test EXECUTE someSubroutine. It can also be useful for injecting a command into a 2nd connected Picomite. Here's a program from some years back in which a picomite connected to a primary picomite receives serial (while perhaps running a program, not just listening) and in addition to executing canned routines on command, can submit EXECUTE some command if sent, say, "! some command": serial control of 2nd Picomite. Note: it cannot be multiple commands separated by ":". PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on FOTS |

I think the Port command and function still require literal GP pin numbers, so to use a string variable for the Port command and function you need EXECUTE. Eg. from keypad program. For n=RowPinGP To RowPinGP+rows-1 SetPin MM.Info(pinno "GP"+Str$(n)),DOUT 'set the Port out pins Next For n=ColPinGP To ColPinGP+Cols-1 SetPin MM.Info(pinno "GP"+Str$(n)), INTH, Key.Pad, PULLDOWN 'set the Port input pins and ISR Next '... Execute "Port(GP"+Str$(RowPinGP)+",rows) = 1 << y" 'set the row to read Execute "x=Port(GP"+Str$(ColPinGP)+",cols)" 'read the columns Though in the latest firmware you could probably simplify that a bit. |

So, for example: -I have two PicoMites that are UART linked, Pico #1 and Pico #2 -Pico #2 has a var named cntr -Pico #1 would like to know the value of cntr on Pico #2 -Pico #1 sends a command$ = "print #[comport], cntr" (to Pico #2) -Pico #2 EXECUTEs the command$ thus sends the value of cntr to Pico #1 If this is true then presumably Pico #1 can also change the value of a var on Pico #2? This is exciting....if I understand it correctly  |

Absolutely. The thread I linked to goes over this in some detail. There's a bit of complicated parsing on the part of Pico #1 to get the answer back confirming that the command it sent was executed. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on FOTS |

 Oh man, this is one of those "I wish it was possible" things for me and I was just about to start doing it the long-winded way.I'll string a couple together  |

I was very excited when the EXECUTE command appeared and saw it as most uncomplicated way of controlling several PicoMites that are running different tasks on a simple network. I have a master 2350 with a USB keyboard using a simple serial link to the other PicoMites. Keyboard errors are ignored, as are calls to PicoMites other than the one with the appropriate subroutine on board that I am calling. For me, it is wizard stuff. I just wish that the EXECUTE command could be retrospectively installed into the MicroMite series; MX270, 470, MZ series and so forth. I tried to get AI to write me a CSUB without any success. 'Picomite Simple Serial Master Option AUTORUN ON SetPin GP1,GP0,com1 ' Open "com1:115200, 256" As #1 'program the commands here onwards...in the form PRINT #1,"COMMAND+PARAMETERS" And on the remote picomite 'Picomite Simple Serial Client Option AUTORUN ON Dim string cmd SetPin GP1,GP0,com1 'Set up comms channel 1 Open "com1:115200, 256, ActionCommand, 3" As #1 Do WatchDog 500 'This recovers from errors not ignored but resets the chip Loop Sub ActionCommand 'Message receipt detected ON ERROR IGNORE 'This avoids system reset if duff command arrives Pause 30 'ensure all characters in command have arrived Line Input #1,cmd 'Get the command Execute cmd 'Action the received command End Sub 'Return from the interrupt |

Yeah, it's just what I need but in my case, I will prefix an 8bit node address. Need to get to my bench to try this. Pulled in all directions, right now. |

Once I used it to dim variables and the variable names were sourced from a text file on a: or b: |
