PIC16 ok with Tait, PIC18 not | Piclist

A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

Had the programmer working already. However, it can't program the PIC18's (PIC18F448 & 458). It did good with PIC16F877. I used Tait's Classic Programmer and IC Prog as the software with IO drivers in WinXP (did some tweaking though). I tried reading a correctly-programmed PIC18F458, but it shows FFFF (or Blank). Similar problem I had recently. There are instances that the EEPROM data have certain values (that I consider meaningless) scattered around the memory map, but the PIC is blank! I tried programming several blank PIC18F458's and 448'. Still shows the same result. What do you think is the problem? Is it the PIC (I tried several PIC18's)? Is it the hardware (this is unlikely to be the problem, it worked with the PIC16F877)? Is it software (but some claim IC-Prog work well with PIC18's)? Or do you think its better to buy a commercial-grade programmer like EPIC Plus? Thanks! Karlo
