When i put my hex file(Blink led in port B) through PICpgn Development Programmer 1.7.8.0
i faced the problem
Quote:
verify Error: Cfg mem ox00000E: PIC=ox3FF3 Buf=ox3F73

i dono how to rectify that.....
PIC i Used = Pic16f877A
Help Plzzzzz......:( :(

Hi,

the LVP config bit (Low Voltage Programming Enable bit) in your HEX file is '0' which means LVP shall be disabled, but if you are using a low voltage programmer this bit cannot be set to '0'!

See also info in the PIC datasheet:
Quote:
If Low-Voltage Programming mode is not used, the LVP bit can be programmed to a ‘0’ and RB3/PGM becomes a digital I/O pin. However, the LVP bit may only be programmed when programming is entered with VIHH on MCLR. The LVP bit can only be charged when using high voltage on MCLR.


Hence, to rectify the problem, you have to set the LVP config bit in your HEX file to '1'.

Regards,
Christian

Again i had a problem :(
RB3 pin can not go high in my PIC16F877A, while programming in LVP mode. what i am going to do that.
Because i connected all the LED's in RB port.
How to use RB3 while programming in LVP mode???

Hi,
if you use LVP RB3 cannot be used for any other prupose, refere PIC datasheet. If LVP is active, the pin must be tied to GND, also if programming is not active.

Christian
