programming problem

[rjmendoza1987]

Hi mikroe,

This is my first use of mikroprog and I am having problem during programming using mikroprog, when i click write, the warning dialog box appears, the device detected is different from the device i have selected, how does it happens?
Then if i continue, the programming was failed. Also the VPP was i think too high, see on pictures attached.

Please help me doing this,


Thank you mikroe,

Hi,

Where are you connecting the mikroProg to ?
Is ti some custom experimental board ?
Could you please attach here detailed photos and its schematic ?

Regards,
Filip.

Hi,

I'm just followed the basic connection for PIC DIP40 on mikroprog manual and i'm surely right.
And this another very strange happened when i tried to click "write" without inserting the mikroprog to the target device, the warning dialog appears again and shows the same, the detected device is different to the device i have selected. I'm wondering why it detect device though it is not connected to the targert device? Is this happening normally if you click write without connecting the device?

Hi,


I'am connecting mikroprog to PIC16F887.


Thanks mikroe

i made prototype pcb for my first use on programming as simulation.
see schematic attached

Hi,

Please, this is not a complete schematic, I will need also the values of the components in the circuit.
So, when the mikroProg is not attached to any circuit, and you press write the same message appears ?

Power from Programmer is not enable???

You dont use any extern Power.
Best regards

Ok i will post actual photo and results.

Yes filip, still same message appears. Always PIC12F508 is the device detected though it is not connected to any circuit.
Then if i continue, the progress bar for programming is running. Very strange, programming runs without connecting to the target device? Can i post video of it so you can watch?

I also upgraded the firmware and followed the steps, but then after i tried still the same message appears.


Helmut, i do not use any external power.. The component value is 100nF for capacitor and 1k ohms for resistor same as requirements for PIC DIP40 programming connections.

leave at all,
i think you should use a JDm progrmer dear

rjmendoza1987,

i have also faced a lot of problems, but now it is fine and i am using JDm programer with the software winpic

[Helmut]

Did you understand?

If you have no ex. Power you must enable the power from Mikroe-Programmer.

Best regards

Of course i understand helmut, i also made that but still same error appears.
I am also currently using my PICKit2 but i have no problem with it, then i bought mikroprog for its nice features but I've encountered such problem like that. That's why i'm asking on this forum for a technical support. I don't want my money to be wasted after all.

Hi,

Ok, the detection of the 12F508 is quite normal.
Please, use a connection as on the picture below, this is an appropriate way of connecting the mikroProg to the 16F887.
I'm sure that it will work in this way.

Filip.

Hi mikroe,

I followed your last post. The result, i scrapped 3 pcs of PIC16f887. It doesn't work after trying.
I'm sure i am right on my connections just like what you suggest.
My mikroprog became useless having problem like that. I have finished my project using pickit and not my mikroprog. Maybe the mikroprog i have bought has already a manufacturer defect before i buy since it showing an abnormalities like that.
Programming is running without connecting the device?? very weird

Thank you..

Hi,

Did you try to program any other chip ?

Filip.

thank you filip, my mikroprog is now working fine for PIC16F887.. next time i will try another device..


Thank you again..
