ICPROG for PICMicro

Select Device

with ICPROG.
 
Note: The screen changes to accommodate the chip features (here EEPROM oscillator, program 'Write enable' and chip configuration bits).

Hardware check

Load Hex file

The next thing to do with the PIC software is programming the PIC by loading up the hex file (unless you have a 12F675 that has an oscillator calibration value that you will want to keep -in this case do a read first).

Note: You have to select the device manually it is not defined in the hex file.  Although ICPROG stores the current device in use between sessions you have to select a new device manually when you start a new hardware project

Note: Fuses and oscillator settings are controlled from the hex file so all you need to do is check that they match your settings in the compiler or assembler.

Hit the open button to load your hex file.

Note how the oscillator, write enable and fuses have changed (controlled from the hex file):

Erase device

The next PIC programming action is to erase the device by hitting the erase device button.  It sends a command to the PIC which erases the whole device including protection bits (in newer devices).  Old devices used to be un-usable after you had set the protection bits!

So this command quickly erases the chip.

Note: You don't have to use the erase button as the program button will overwrite the chip contents anyway.  It is sometimes useful if you want to convince yourself that the program is actually programmed into the device correctly.

Program device

The program device button does just that it programs the contents loaded from the hex file (in ICPROG memory) into the program memory of the PIC micro.  If there is any EEPROM in the chip then it programs this as well. Finally it programs the configuration word.

Verify device

The verify device button reads back the entire contents of the chip ensuring that it matches the hex file (loaded into ICPROG).

Read device

The read device button reads back the entire contents of the chip into the currently selected buffer (shown at the bottom of the ICPROG window). So you can save the hex file or compare it to the contents of another buffer.

These are the only controls you need for successful PIC programming using ICPROG.
