Hi

I seem this evening to have a device ID error when compiling to chip.

Jumping over to the MCs IPE I can connect, detect,read,erase,verify from with MC IPE but I get this error when trying to compile to chip within flowcode

Code: Select all

Target folder: C:\DOCUME~2\_PRJ\Examples\V6_COM~1
Source name:   C:\Documents\_PRJ\Examples\v6_Completed Systems\TestPWNSounder.fcfx
Title:         
Description:   
Device:        PIC.16F.16F877

Autoclose turned off


FINISHED

This was working fine, the graphic display project I finsihed, same device, same board is fine, in fact the code was still loaded before I used IPE to erase the device, that now has the same error

Undr compiler Options > programmer options seem unchanged and all valid

Location

C:\Program Files\Microchip\MPLABX\v6.00\mplab_platform\mplab_ipe\ipecmd.exe

Parameters

/P$(chip) /F"$(outdir)$(target).hex" /TPPK3 /M /OL

Very odd behaviour

What is FC8 looking to do that is different to MC IPE ?

Hi.
I believe device ID 0x2080 belongs to PIC16F887.
Is that the microcontroller you are using since that's what's being detected?
The reason I ask is, it looks like you have selected PIC16F877 within Build, Project options.

Martin

I think I need my vision checked, spot on and thanks for spotting the error

That's great.
At least you are sorted now.
Thanks for letting us know.
