Pickit3 vs 12F683 |

Ok.. I've confirmed that you can't program a 683 with the kit3 , arrgh..
msg comes up '....internal oscillator and internal MCLR....' is a bad combination. I'd have copied and pasted the message but that doesn't work for me either!!
Now IF you use the external MCLR and or ext. xtal, that 'should ' work, though I haven't tried.. maybe later...
Obviously something about the Pickit3 as both my original PS+(white) and flash PS+(black) work fine.uchip knew about it as the message pops up...hmm....
Seems 'silly' to me that it's NOT backwards compatible....sigh...
I may look at a newer PIC though time=$$ but it is a challenge.
I _knew_ I should have listened to myself and used an 18 pin PIC....

This is actually a chip limitation.
Because Vdd is already applied, it has to use what is called the "Vdd first" programming method. This method is not available on the chip in your configuration (from the programming manual):
"This method can be used for any Configuration Word selection except when INTOSC and internal MCLR options are selected(FOSC<2:0>=100 or 101 and MCLRE=0). This technique is useful when programming the device when Vdd is already applied".
Because the Pickit3 has no ability to turn off Vdd, this is the programming method it has to use.... |

Funny enough I'm working right now with the 12F683.
Work great with the Pickit2!
I think Pickit3 is bad for anything else except dspic33, pic24 and pic32 series. _________________ Regards,

hmm.. had a look at PICs and think the 12F1752 is a nice 'goto' PIC. Seems to have a lot of nice features for a buck !
Hopefully PICkit3 will program it....
...silly me, thinking ICSP was the same for 2 decades.....

Or get a Pickit2 just in case ... they sell for cheap now! _________________ Regards,

seems real silly to buy a #2 when #3 is supposed to be better.
heck my ORIGINAL Picstartplus works fine, just a pain not having ICSP.
besides the coins for a #2 could offset going to the 12F1572....
life ain't easier the older I get.
