HL-SDK Posted October 20, 2006 Report Share Posted October 20, 2006 Hey, My midibox SID worked 2 days ago, and I was messing around with the LCD.Before this, I could play the SID and everything. Everything was perfect, I could upload code, display messages and everything. Yesterday I forget what I was doing but anyway... Now I have disconnected the LCD (I am ordering a new one for other reasons) and the DIN and the SID and I think it has the code on there for the sidplayer.The problem is, when I had the LCD on, it would display a 1x20 line of blocks (it was not a brightness/contrast thing). That's fine, I'm getting a new LCD but the real problem is that my core won't send me an upload request when it powers on... The only reason I can think this would happen is that my heatsinked LM7805 (or 7905 I forget) was left on for too long and got a capacitor too hot or something but I highly dobut this.So now everything is disconnected except for the midi in, midi out, and power to core...I can't upload code because core isn't sending midi out.I dont know what else I can say to help :-/ (btw, the case/box I made is looking good ;))----EDITI have a silly scope I can use to check core pins if you know of any that should be sending midi messages or whatever, this is just very dissapointing because I was having such a great time! (I am 95% sure it isn't a software problem)Measured Tx PIC pin with SillyScope and it's a constant 5v (I am sending LCD messages from MIOSstudio)Measured Rx pin and it's sending dataShorted the 2 and got a loopback (midi out from MIOSstudio came back through in)So it's not my midi interface, I really think it's a PIC problem and I have ordered anotehr from smash but this pic + LCD is a nice 15$ mistake :'(Would reburning the PIC be possible?

Laslo Posted October 21, 2006 Report Share Posted October 21, 2006 I had the same problem of fiddling around with the LCD and then my core stopped working, i eventually narrowed it down to the PIC which i reburnt but still to no avail, so i tried a second PIC i had, burnt that and it was alive again.So possibly the PIC died but im about as far from an expert as you can get.

HL-SDK Posted October 21, 2006 Author Report Share Posted October 21, 2006 Thank you for the reply, I dont know what could have possibly gone wrong but really I think your solution is the best idea...So... the pic and LCD should arrive in a few days and if they don't work, I am going on a school shooting.but they'll work Quote Link to comment Share on other sites More sharing options...
toneburst Posted October 26, 2006 Report Share Posted October 26, 2006 ...and if they don't work, I am going on a school shooting.but they'll workThat's a bit extreme, mate....I know what you mean though.The problem I find doing projects like this is that I'm really only following the recipe (as another forum member memorably said), without really fully-understanding what I'm doing. Which is fine, until something goes wrong. My other problem is I have a boring job, and therefore far to much time to obsess about the colour of LCD screens and what kind of enclosure to use.Alexhttp://www.toneburst.net Quote Link to comment Share on other sites More sharing options...
