Modifying EPIC.INI for problems with FLASH MCUs
On some computers, you may encounter intermittent problems when attempting to
program Microchip's FLASH devices with the EPIC™ Programmer using EPICWIN
software. Users of meProg software should not attempt these modifications.
These changes should only be made for the FLASH parts, which are denoted with
an "F" in the device number (16F877, 18F452, etc.)
These parameters may be changed to suit your computer. This is
accomplished by editing a file called EPIC.INI, which is found in the directory
where your EPIC software is installed.
Open the file in a text editor such as Wordpad. If you use a word
processor, make sure you save the file as plain text. Depending on the
software you use, you may have to select "plain text",
"ASCII", "text only", "unformatted text", or other
settings that won't add formatting information to the file.
The information in the file is grouped according to the device part
number. Each Microchip MCU has a group of parameters that represent its
programming specification.
The parameters that control the erasure and programming of the chip may be
increased for slower, more reliable operation. These parameters are named
ProgTime and EraseTime.
Increase the value of these parameters, then save the file and restart the EPIC
software. Don't increase the values beyond 20000.
Below is an example of a change for the PIC16F877. The EraseTime has
been increased to 20000.
[PIC16F877]
CoreType=14
CodeSize=8192
DataSize=256
EEPROM=1
ProgCount=1
ProgMult=0
ProgTime=5000
EraseTime=20000
BaseConfig=0x3fff
ConfigMask=0x3bff
OscMask=0x0003
