CCS has been very responsive in clearing up what the issues are. We had our answers by the end of the day today.

The oscillator issue is corrected by adding the PR switch to the fuse info

We purchased the PCD compiler yesterday, bad choice. Writing the simplest program possible, setting the fuses and declaring 1 int variable, was too much for the compiler. It is impossible to use any o ...

OK, will do..

From our other posts you know that we are developing CAN for J1939 requiring support for the INTs on the 18F parts. We will watch for the next PRODUCTION release from CCS and purchase ...

OK,

We also have, but have not installed:

CCS 4.031.30.16

Would you recommend upgrading to that version from 4.025

We are currently developing on:

PIC 16F883
PIC 16F887
PIC 18F6680
PIC 18F8660

All part of the same project.

Hi all,

Our environment:
CCS V4.025
CCS MPLAB Plug-in V6.20
XP SP2
MPLAB V7.60
PC HP-Pavallion

Just for reference, we don't see any of this when using MC C-18 compiler.

There appear to b ...

ckielstra,

That's great...!

ckielstra,

Your code fragment:

#int_global
void InterruptVectorLow( void )
{
if (PIR3 != 0x00)
J1939_ISR();
}

results in Unprotected cal ...

ckielstra,

Thank you again for your help.

Do you know the method CCS uses to arrive at the addresses for the INTs that they create in the device profile that they publish. I would love to know t ...

PCM Programmer,

Here is the function we are trying to replace from PIC 18C Compiler;
#pragma code InterruptVectorLow = 0x0018
void InterruptVectorLow( void )
{

Hi All,

Working to finish the CAN J1939 conversion using interrupts. It does not appear (or I missed it) that there is an int to service PIR3 in the list of INTs for the PIC18F6680. Setting the bit ...

FINALLY, I figured out how to do this in CCS... Here is how it works...
In CCS here is a Structure inside of a Union...

I am converting the J1939 PIC-18 Complier code. There is a (Structure inside of a Union) in PIC-C;

PCM Programmer,

In description they sound identical, but i missed the fact the the IOCB register is missing in the 4410. I guess bit testing is the only other solution. Thanks for your help....

We are running CCS 4.025

We are porting an application from a 16F887 to a 18F4410. For the Microchip descriptions of how the interrupts function on PORT-B for both devices we find them to be identi ...
