Hiyas, I built Jim's programmer (uses 74HCT125 now)... anyway now I have the = weirdest results yet (yay)! Just as an example, I'll do some stuff riiiight now..: * Turned on +12V, +5V (actually more like 3.6V - 3xAA rechargable), but = programming datasheet says this is fine) * Loaded FPP, checked setup (ok) * Clicked read, ok * Woo! Screenfulla' 3F8C's code, 00 00 etc. data * Clicked load, loaded FLASHLED.HEX * Clicked program, ok * "Failed to program code!" instantly * Clicked read, ok again, for kicks.. got 2C24 followed by 8 0000's, = then all 3F8Cs. Near the end, 3FFF x4, 0000, then 3F16 09A5. Data is = now all 80's! Config has also changed, from "####" to "2C24" * Reset power supplies, clicked read, got 3FFF, load of 0000s, data all = 0000s. * Ooie, transistor is hot.. I'll try turning it round *shrug*.. nope, = now it all reads as --Blank-- and still fails to program.. turned it = back, reads 3FFF then 00s again. * Doesn't work if I connect +12V connectly to MCLR either (with 100ohm = resistor) I have... no idea.. if anyone is recognising anything click that lil = reply button :) Thanks -Kieren -- http://www.piclist.com#nomail Going offline?
