Programming Problem with PIC16F819
I'm using PBP v2.46. Programmer is PICkit 2 with v2.10 firmware. My program uses about 1950 words. Error message received after a programming attempt is:
"Verification of configuration failed". Here are the configuration lines I'm using:
@ device pic16f819,intrc_osc_noclkout,wdt_on,pwrt_off,mclr_ off,bod_off
@ device cpd_off,ccpmx_off,debug_off,wrt_off,protect_off,lv p_off
If I comment out the configuration lines the part programs successfully. Any ideas?

Hi Richard,
something in one of those statements probably is in error, try removing individual statements until you find the one or more errors. Looking into the data sheet makes me suspect the capture compare statements.ccpmx_off. Does it compile but fail to program or does it fail to compile?

Compile is okay. Programming n.g.

Joe, Okay.... I tried your suggestion. The item that causes the programming failure is: intrc_osc_noclkout
Do you see anything wrong with this?

Hello Dick,
I notice there is an added space in the lvp_off config in the second line (you have: lv p_off). Could this be the problem?

Hi Andy,
The extra space in lvp was added automatically by this forum's editor software. The space is not there in the actual program. Otherwise, the program would not compile. Thanks for the observation.

Hi Richard,Originally Posted by Dick Ivers
Try using it this way using PM as assembler, I'm still trying to get MPASM version to compile.
Code:@ DEVICE PIC16F819, INTRC_OSC_NOCLKOUT, WDT_OFF, LVP_OFF, PWRT_OFF, PROTECT_OFF, MCLR_OFF, BOD_OFF @ DEVICE CPD_OFF,CCPMX_OFF,DEBUG_OFF,WRT_OFF

Programmer fixed with the following changes as suggested by Microchip support:
1. Upgrade PICkit 2 programmer software to v2.40
2. Under "Tools" set "Use Vpp First Program Entry"
3. Set Vdd PICkit2 "ON"
4. Set voltage to 5.0
