I am trying out some basic functions of CCS.
I want to do some RS232 comms and have just #included rs232.h and the compiler immediately throws up errors.
The first line in rs232.h is #device PIC18F4520 and throws the error "Can not change device this far into the code".
18f4520 is the device specified at project creation so I don't know why it thinks I'm trying to change it?
#include <TestSerial.h>
#include <rs232.h>
void main()
{
}

Because 'testserial.h' is in front of it.....
The order needs to be:
Load the processor file. This sets the device.
Set the fuses.
Set the clock rate.
Then have the setups for things like serial and I2C.
Only then start actual 'code', including driver routines etc..
rs232.h is much too 'late' to be setting the device.
