PCD: Can not change device type this far into the code

Hello,

I am receiving the following error while compiling:

Error 23: Can not change device type this far into the code.

The error arrow points to the line "#device *= 16" in the following code:

Code:

#include <30f5011.h>
#include <DS1631.c>

#device *=16
#device ICD=true
#fuses EC, NOWDT

#use delay(clock=40000000)
#use rs232 (FORCE_sw, baud=9600, parity=N, xmit=pin_F5, rcv=pin_F4, INVERT)

void main() {
BYTE value;

init_temp();

do {
value = read_temp();
printf("%u\r\n",value);
delay_ms(1000);
} while (TRUE);
}

I have not changed the 30f5011.h file.

Also, I have checked the forums for this error and it seems to occur when someone redefines the header file which I have not done here.

This error first appeared when I added the following test code from the CCS examples:

Code:

//// ////
//// This driver returns a high resolution value. For lower ////
//// resolutions use the DS1621.C driver as it is compatible with ////
//// the DS1631. ////

++++++++++++++++++
Code deleted.
Reason: Forum Rule #10
10. Don't post the CCS example code or drivers

Any ideas? Thanks in advance.

In CCS, don't put #include files before #device statements.

Move the line in bold so it's below all the other lines shown here:

Quote:

#include <30f5011.h>
#include <DS1631.c>
#device *=16
#device ICD=true
#fuses EC, NOWDT

#use delay(clock=40000000)
#use rs232 (FORCE_sw, baud=9600, parity=N, xmit=pin_F5, rcv=pin_F4, INVERT)

Also, the #device *=16 is only used with the PCM compiler (16F877, etc.).
It's not needed on 18F, 24F, dsPIC, etc. Delete that line.
