This is a working RS232.... ICD2 !!!!

icd01020605.hex

euhhh always 16F877A
i try to understand ???
the original hex file provided by CrayzyDuck is for a 16F877 (NOT a 16F877A) even if its written 16F877A in the PDF file, is it the real situation ?

CrazyDuck's hex file appears to combine the BootLoader and the firmware files into one file. It will work with either a 16F877 OR a 16F877A, but you will not be able to update the firmware to work with different device families or to update to newer firmware. CrazyDuck's hex file will report that it is version 2.0.21 (file ICD01020021.hex in ICD2 directory of MPLAB?) while the latest version is ICD01020411.hex (MPLAB 6.43).

Hi,
I'll put my firmware in 16F877A, and it works at home. But I've some problems at work. I'll try the other firmware.

Hi,
You can find FDS4435 for free sample on fairchild semiconductor website.
Best regards.

I've some problems with ICD2 on my work's computer. I can connect to ICD2, but I can't program anything. I think I've problem with my computer RS232 levels.

Hi,
I solve my problem. It was about the "A" suffix of 16F877.
You must not use 16F877A to put the firmware, but a 16F877.

HI,
The firmware can be updated with no problem if you use a 16F877.

Have you tried my modified bootloader in a 16F877A? I have had no problems updating firmware so far.

mplab 6.5 download

Yes I'tried it but I can connect to ICD2 with it !!!

I forgot to say, as this is just the bootloader MPLAB reports connection failed. If you then try to download the firmware it should work.

Hi,
The bootloader from Zaphod42 works well. Put it in a 16F877A with a classic programmer. Put the pic on the ICD2, and download the Operating system. That's all!!!

Thanks to Zaphod42.

Can Microchip's ICD2 work with CCS compiler?

Tahnks.

CCS has developed their own ICD for new PIC families that communicate with their IDE via USB and RS232.

Can Microchip's ICD2 work with CCS compiler?

yes, just integrate CCS in MPLAB :!:

Hi

SI4435DY and HAT1026R are similar, do not know if they are easier to find for you.

Good luck

Hi,
FDS4435 are P channel Mosfet with logic voltage command. You can replace by any mosfet wich have the same characteristics.

I found IRF7204, same logic P-Mosfet, same footprint

unable to connect with mplab icd 2 (com3)

Hi,
Please read the last posts on this topic, you'll find the solution and the correct bootloader from Zaphod42. This bootloader works fine with 16F877A. Put the boot in the PIC with classic programmer, put the pic on the ICD2, connect with MPLAB and in the debugger menu choose, download operating system. Thats all.
