FLowcode V5 + PIC18F45K22 Crystal Clock .. Need Help Please

[south_wind]

I'm trying to program PIC18F45K22 with flowcode 5 but I have a problem with external clock

I tested my program using 1 sec delay LED but it gave me a delay not equal to 1 sec

even when I interface LCD its not working

Could you please tell me what is wrong , this is my first time I use PIC18F

Thank you

Hi south_wind ,
Can you post your flowchart and a full circuit diagram please.

Hi Medelec35
I attached my simple test flowchart
I'm using ready for pic from mikroelektronika as a hardware
thank you ..

[medelec35]

Can you please post the flowchart itself, rather than a screen shot.
It makes life easier for us to check it all out.

Since you have not got the free version of Flowcode V5, you will need to register for an account upgrade so you can post in the V5 section.
Take a look at this link

yeah sure sorry for that , I'm using 8MHZ external crystal

I can help with this issue,
But for the future reference you will need to register for an upgraded account as stated above.
Issue with the flowchart you have posted is the configuration settings are different to the screen shot you posted.
For example in the flowchart you posted, the watchdog timer is enabled you should start off with it disabled.

The extended instruction set, single supply ICSP and portB A/D should also be disabled.

When you program make sure you see programming has been verified.

You are on the right tract to make sure LED is flashing at the correct rate.

Normally LCD Start is placed before the start of the main loop.

Hello medlec35 and thank you for helping me
when I used a 8mhz external crystal and put the setting into 32MHz I guess it works fine , I don't know why ?!!
