I try to get the attached program to work in a PIC18F4620 but unfortantly I can not find the right settings por this pic can anyone help me ?

I have changed
C:\Program Files\Matrix Multimedia\Flowcode V4\BoostC\boostc.pic16.flowcode.exe
to
C:\Program Files\Matrix Multimedia\Flowcode V4\BoostC\boostc.pic18.flowcode.exe

All other settings are default.
I think problem is on the Chip/Configure/Expert settings page.

Thanks for any help.

Hello Albert,

To get Flowcode to compile to an 18F device you do not have to change the setting in the compiler options window. This is done automatically for you.

To get the configuration correct I would try the settings as shown here.

These settings should match most applications with a crystal speed over 4MHz. All other settigs that cannot be seen on the image above are set to disabled.

I have had to changed Fail-Safe Clock monitor to enabled and Brown Out voltage to 2.7 Now my program starts but is running about 30 times slower as it must run.

Edit
I found the problem. I only need to change 'Brown Out voltage to 2.7' remove jumper J18 J19 from the board and directly connect a xtal to pins 13 and 14 of the PIC18F4620

So this problem I am facing is a hardware failure of the EB-006-00-7 board. It seems that the OSC on the board is not starting properly. For now I can live with connecting a xtal to the pins 13 and 14 of the PIC but hopefully some advice on changing the local OSC on the programmer board will come to solve this problem.
I am using PIC18F4620-I/P manufacturing stamp 09364C9

The problem is solved Jumper J18 J19 had a bad contact I replaced it now all works fine
