Microcontroller development board version3 software

Post by Desdewit »

Hi Guys

Are there any old or upgraded software available for a PICmicro Microcontroller development board version3 HP488-00-3.
Does it have any other function on the board except for running the usb?

Hi Enamul

Thanks for the reply, I realy hope someone can help me with this. :cry:
A few days ago my power supply for my V3 development board over heated & stopped working for unknown reasons. After replacing the power supply my programmer was working again with no obvious problems but for some reason if I program my old working rs232 test program with Hardware RXint & Software RB0Int the software side give me strange errors.
If I send a byte via Pc for instance Dec 1-80 the pic will reply with the correct value but as soon as I send something like 90 it reply with 218, 100 reply with 228 or Ascii A –J will be correct but ascii K will reply with <(CB)> and ascii L will reply with <(CB)>.
I’ve also tested the following.
Test the software on different pins with and without interrupts.
Test and replaced max 232 chip (Both channels working correct)
Tested & replaced different versions of pic’s
Tested both rs232 ports and serial software on two different pc’s
Used flowcode on a different pc to load the program
Could the problem be the usb interface chip on my development board not programming the correct way. (It does feel a little hot sometimes)
The strange thing is that only the software port is giving problems.

HI

I have looked through the code and the code is fine know issue is there. There must be something wrong with the hardware. From PC are you sending string or character; what is the length of wire?

Hi Enamul

I'm sending 1 Character at a time to test over a 1m serial cable.
The problem is that I know my original program was working and was sending and receiving multiple bytes without a problem.
The receive problem only started after the suspected short, but why only on the software part of the rs232?

Yes, So far I can not find any other problems.
That's why I think it might be the program not loading correctly.

I don't think that. Because I was using RS232 with RB0 int and it's happen to miss some data because of long distance but your distance is only 1 m. So confusing..You know later on I have move to CAN and CAN is absolutely reliable.

Do you know if microchip has cheap programmers that can program the same chips as the V3 Development board or the EB006?
I urgently need to replace my programmer but our local supplier can only get me a matrix EB006 early in January 2013
:( :x :cry:

Hello,

You can program the Eb006-00-7 and above directly using the PICKit2/3 with the ICSP header that is on the board, for the HP488 v3 and EB006-00-6 and below you will need an adapater to change the ICSP on the PICKit2/3 to an RJ45 connection to plug into the RJ45 socket on the boards.

Hi David

I'm going to get myself a pickit 3 but would still like tor repair my HP488 v3 development board.
Do you know if I can still get a replacement chip with firmware for the HP488 v3 board.
