Field code upgrades - how to do it?

[Dave]

BrianT , I have had real good luck with the IOGEAR usb to rs-232 converters. Especially when used with MCLoader.....

Are you using a level converter in your system (max232)?

I didn't experience any problem with USB to RS232 converter of different brands, but always using a level converter on my system.

Cheers

Hi Aratti,
Yes I am using MAX232 chips for true RS-232 level and polarity. The problem with USB to RS232 converters seems to be the increased, and apparantly varying, end to end delay between the MCLoader sending a character and getting a reply.

My hope is that someone has found a tweak to MCLoader or has a rival product that is tolerant of these variable delays.

Cheers
Brian

BrianT, I have not had any problems with MCLoader w/ the IOGEAR USB to RS-232 converters and use them all the time here at work.. I have also used the FTDI USB to TTL converter cables in some designs to get away from using an RS-232 level convertor. They also work GREAT with MCLoader...

Hi,
Not much help, I know but I'm using a FTDI TTL-232-5V cable without trouble. I also have a SureElectronics PIC-board which sports a CP2102 USB<->Serial chip, a ATEN UC-232 USB dongle as well a cheap one I got on EBAY and they all seem to work fine with MCLoader.

I do not know how related is my reply, but is worth I think to mention.

Pickit3 has memory inside that can store a hex code and then program the connected with ICSP lines controller by just pressing the button. It does not need a PC connected, just a power supply.
