ERROR -> Communication "Invalid Checksum"

[valexe666]

I have WinPic800 Ver 3.55d and hardware Ver 3.52
Hardware is GTP USB-232 with FTDI232.
Windows sytem is 2000

What is the problem.

when i try to read or write any PIC of 16fXXX i receve at final this error:

ERROR -> Communication "Invalid Checksum"

Whn i write any PIC 16Fxxx pic is writed and is working OK but with same error message from winpic800

With all 18fXXX is working with free errors.

Anybody know what is happen here?

Any help can be very useful.


Thanks in advance.

Hillo :

it reviews the part of communication -> RTS , DSR etc .

The condenser  100uf/25v.  of the feeding also is important.

Although serious better to modify to Gtp-usb with 18F2550  .

But simple  

luck
