Hello,
Ok thanks for the reminder. I have managed to make this change to the component. Are any of you able to test the code for me before I put it into the Flowcode PIC release.
To start copy the attached file into your "Flowcode v4/Components" directory.
Then use the CAN2 component and the custom code feature go into the defines section of code for the CAN2 component and change this line.
And change it to this to activate the internal functionality.
Let me know how you get on.

Hi,
I have had a play with this today, but have not had much joy.
I downloaded the new CAN2 component and installed it as per instructions. I then went into custom code where I found the line in question but found it already to be edited as per your post. I then wrote a very simple flow chart where the CAN initialises then sends an ext identifier string once a second and toggles a led. I loaded the file into a target board I made up a while ago with an 18f2580 and a CAN voltage shifter (circuit as per a microchip datasheet).
The program compiled and loaded fine, the LED toggles but the CAN string does not appear to be transmitting.
This could be a hardware issue but I don't have anything else to test with.
Thanks
MW

Hello,
I have internal CAN hardware setup at home so I will have a go with the code this weekend and see if I can get it to run correctly.

Hi,
Did you have any luck with this?
Cheers

Hi Ben
Based on posts in the forum members on the same subject
http://www.matrixmultimedia.com/mmforum ... 29&t=10445, which I put here is still no solutions to the problem of the same and I would like to know whether there is a problem in the program could not be resolved
Thanks

Hi Guys,
Just started to play with Internal CAN (PIC18F25K80), I wish to run a CAN baud rate of 1 Mbit. I need to also select a suitable Oscillator freq for the chip to allow for this.
The start of this thread mentions a calculator in the components properties but I can find it anywhere... any pointers?
Regards, J.
P.S.
I've just selected a 20MHz Crystal for the Pic Osc and set the CAN config BRGCON1 to Ox0
This gives me a 1Mbit Baud Rate.
I also changed the PPP config settings.
Oscillator: HS
But left the 'PLLx4 enable Bit : Enable'
Will the PLL setting try to give me a 40MHz FOsc ?
