Very Simple ICSP Programmer

[Art]

I have just set up a 16F877 circuit for ICSP using this interface
with my desktop PC. (XP service pack 2 BTW). No problem with
read, verify, or erase

I used the settings with IC prog suggested earlier in the thread:
I/O delay 20, JDM programmer, Direct I/O with nothing inverted.
Have you have also powered the pic seperately with 5 volts while trying
to use this interface?

Cheers, Art.

Hi Art,
Please, could you tell me what are the connections that you have made between the Serial port and the PIC16F877 ?.

PIC Serial Port
MCLR/Vpp ---- ?
RB3/PGM ---- ?
RB6/PGC ---- ?
RB7/PGD ---- ?

Thanks a lot !.

breogan, You only need

MCLR/Vpp
RB6/PGC
RB7/PGD

to flash a program into any pic using high voltage programming (+12 volts) on the Vpp line. Now if you are planning on programming it using low voltage programming then you need:

MCLR/Vpp
RB3/PGM
RB6/PGC
RB7/PGD

If you plan on using a boot loader then you need to use 1 of the first 2 options loading a bootloader hex file into the pic (if it supports bootloading). Then all you need to do is connect the RX/TX lines from the PIC thru an inverter such as a Max-232 to your pc's comm port to load your application software from that point on. I perfer to use the bootloader method of loading the application code myself.

Thank you Dave,
I will try with
MCLR/Vpp
RB6/PGC
RB7/PGD

I'm tired of programming/erasing 16F74A /JW version...

Hi All,

I've just bought my first 16F88 Chip.

I can confirm that this chip programs using the Very Simple ICSP Programmer too!

Hi Squib,
I haven't tried it yet, but I can't see a reason why it shouldn't if it is supported by the programmer software.
Even the 16F88 is a PIC ;-)
