Damaged EB006- 8 board ?

[Dr T JONES]

EB006 - 8 was working well with PIC16F88 then i changed the chip to 18F452 and tried programming this with certain new programmes without any success. I then swapped the chip back to the 16F88 and i can programme the chip (as checked on a breadboard) but PORTA and PORTB not working when connected to EB006-8. Have tried EB083, EB004 and EB005 without any success. Any ideas ?

Can you post a flowchart that is not working on Eb006 programmer.
I will see if I can spot any issues.

[Dr T JONES]

The programmes work correctly on both as i have a different PIC board and both chips work with the programmes.

My problem is i can't test them anymore using the EB006-8 board and the output boards connected.

[Dr T JONES]

Im using C and assembler programmes not FLOWCODE.

[medelec35]

Oh right I see.
Are you using the internal osc or external osc?
I'm assuming VDD is correct since its allowing you to program, but just to make sure maybe best to measure it.
Then program 16F88 with internal osc adn set all the pins of ports to high,delay 500ms then all pins of all ports to low, delay 500ms then repeat forever.
If you have LED eblock or use meter to check each pin.
If your using external osc, then could switch2 be faulty preventing crystal from being connected to the microcontroller?
Reason for that logic is the most of the pins of target device (there are exceptions) are connected directly to the ports.
So if say portA0 is working on the prototype board, then it should also work on EB006 (using internal osc)

[Dr T JONES]

Vdd ok

Tried everything suggested without any luck.

Will have to send EB006-8 back to Matrix again!

Hi
Can you post a c-file if its sensitive you can pm it and i will shred it after ive had a look, another thing is have you tried to program to new chips as well does it work wtc

Regards
Dazz

[Dr T JONES]

Have tried 2 or three other chips without any luck. As I said it programmes the chips ok but when testing on the EB006-8 board no outputs visible on all the output boards I've tried. When i check the chips on my other PIC testing circuits the chip works well after being programmed on the EB006-8 board.

Hello,

Can you post the C or Hex file your using? I would expect that it's something either in your code or configuration that is causing the device not to run your program.

[Dr T JONES]

Here's the test programme i'm using. Like i say it programmes the chip ok but no output when using EB006-8 and EB083. When i use my own test circuit the chip works as it should.

Heres the ASM file.

[Benj]

Hello,

There is no configuration in the assembler file.

In the PPP software click the configure PICmicro button and in the config window that appears click the autodetect chip button, this should set the default device to the 16F88.

Next click Ok and then click the open button to load in your compiled hex file, this loads in the hex file formatted for the 16F88 device. If you load the hex file with the default target set to an 18F device then the hex file will not load correctly for the 16F device.

Next click configure again and select the right settings to allow the device to run, something like this will work with the EB006 Oscillator switch set to XTAL.

Then click the Ok button again and now click the Send to PICmicro button.

Fingers crossed your program should run after programming completes.

[Dr T JONES]

Yes i do this every time i programme a PIC chip, tried again now with no success.

As i say the chip is programmed correctly as it works on my own testing breadboard circuit, just won't work with EB006-8 and EB083.

Hello,

I will contact you privately about a possible return of the board to check it.

[Dr T JONES]

Ok thanks.
