 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. |

I can't work out what is happening here..... I've rebuilt a board for my garage door sensor project, and before I even enter much code am getting a frustrating error: [1] SetPin 2,intl,button Error: Unexpected text This is the code..... SetPin 2,intl,button SetPin 14,dout SetPin 25,dout Sub button End Sub Pulse 25,1000 Pulse 14,1000 Any interrupt code I try and use returns this error..... I can make the pin a digital input and it works ok. This is a micromite 4.6 Beta 1 if that is important..... |

That should work OK. "Error: Unexpected text" means that the interpreter ran into something in the command that should not be there. Perhaps you have some control characters embedded in there that is throwing it off. The other point is that 4.6 Beta 1 was in the very early days of the MX170 Micromites and it had a lot of bugs. I cannot recall if one of the bugs affected interrupts but it is very possible. Geoff Geoff Graham - http://geoffg.net |

I was just wondering that, about the beta status.... I'll clear out the editor and start again, if that doesn't work it sounds like I need to start desoldering a chip..... :( |

Why? It is usually easy enough to flash the chip while in-circuit. Jim VK7JH MMedit |

I have no doubt.... if you have a 'flasher'....  |

Must have been a beta bug or something similar..... I desoldered it and dropped in a 4.5D chip I had, works perfectly..... |

@ Lee3 Have a look at the Microbridge on Geoff's web page. If you cant build one yourself I'm sure someone will help you out. Paul. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

Thanks, I’ll certainly look into it, it doesn’t look too tricky... |

ALWAYS design the ICSP into your boards.  Either that, or include the 1455 'MicroBridge' circuit as standard. One or the other, otherwise you cannot update the firmware in-circuit as you have found out.  Smoke makes things work. When the smoke gets out, it stops! |

Or, failing that, use a socket rather than directly solder the chip.....  |

There's no problem with directly soldering. All the SMD versions HAVE to be, really. Take the SSOP version.  The trick is to ensure you leave an ICSP header, or if not that, then the 1455 interface so that you can update MMBASIC via USB. You obviously were able to replace the chip, so good on you.

I must admit, I wasn't looking forward to removing the chip, but my spring loaded solder sucker did the job brilliantly. Didn't need *that* much force to pull it out afterwards.... :) I'm looking into chip reprogramming now.... I'll have to add that to the repertoire..... |

you might like to have a look at the 'constructor guide' here: http://www.thebackshed.com/docregister/ViewDoc.asp?DocID=19 it is the most basic/cheap pic32 programmer, an arduino nano + half a dozen parts that can be bought on ebay china for just a few dollars landed. cheers, rob :-) |

or have a look at this.... Pretty cool stuff on his website as far as chip, programmers and SPEED! |

It's essentially the same as the 1455 mentioned already except it's remarkably expensive whereas the 1455 is almost free. John |

I've opted for the easy path at this stage, and ordered a Microbridge kit from Silicon Chip.... Thanks for everyone's replies... |

@ Lee3 When you have the Microbridge up and running download Robert Rozee's 'Picprog GUI' either from SC or RictechNZ which is Grogster's site. It makes flashing the chip a breeze. Thanks robert.rozee for making things so simple. Paul. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

I use a Mac, so it probably won't be as simple.... There does seem to be ports for pic32prog around, I just need to work out what I need first! |

I suppose Mac's have their drawbacks but at least you don't have to put up with Win10 Paul. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |
