I'm kinda stuck here - working on 2 ren24's - all built but I seem to be snagged at the PIC programming part - I'm using a "JDM" type "serial" programmer to program the f688's - I have tried all sorts of configurations, PWM, DC, regular - but nothing seems to work. Curiously, I can program a diag PIC and it does what it supposed to. No framing errors, data led when receiving, if I change the baud rate I do get framing errors, so I have the proper baud rate set and I can remove that PIC, flash the .hex file for regular or PWM but no go - data comes in on pin one of 75176 and goes to PIC, but PIC is non-responsive to any of it.
I should mention that I purchased a PIC programmer from evilBay for $10 and it is supposed to program 688's, but of course the program it came with, I-C prog, which is a freeware app, doesn't have those in it's list, nor does PonyProg, so i am using a pin compatible alternate to program them as 16f676 or 16f630 - it appears the memory is larger in these guys, which shouldn't matter, and the prog sez "verified ok" and to confirm that I erased them and read them then programmed them. I suspect that my programmer is not working as advertised so I need to break down and spend a little extra money to get a decent PIC programmer or at least one that is known to program the 16F688. As mentioned, I can flash the DIAGS and they work fine, but not the regular code.
If anyone has some suggestions, I'm all ears.....
So I'm back to piggy-backing 595's on top of the ren 24's (sorry Peter and Phil) and feeding the 595's 2803's to the opto's of the REN to at least get some blinky action this year......
Having a fader Christmas this year is looking rather not achievable at this time....:(
