Error "#DEVICE required before this line"

[micro17]

Help me please, problem with this code...


/*
LED on gpio.1 blinks at rate controlled by
potentiometer connected to gpio.0
*/

#include <12f683.h>
#device adc = 10 Error "#DEVICE required before this line"
#use delay(clock=8000000)
#fuses nowdt,intrc_io,put,noprotect,brownout,nomclr,nocpd

#define LED PIN_A1 // define pin for LED

int16 ad = 0; // holds 10-bit a/d value 0 to 1023

void init(void) // hardware initialization
{
output_low(LED); // LED off on boot
set_tris_a(0x01); // gpio.0 input, rest outputs
setup_oscillator(OSC_8MHZ); // set for 8MHz internal osc
setup_adc_ports(AN0_ANALOG); // a/d enabled on gpio.0
setup_adc(ADC_CLOCK_DIV_16); // a/d clock /16 @8MHz,Tad=2uS
setup_comparator(NC_NC_NC_NC); // disable comparator module
}

void Blink(int16 adval)
{
int16 rate;
rate=adval*2; // ~0-2Hz blink rate

output_high(LED); // LED on. gpio.1 o--/\/\/\---|>|---o gnd
delay_ms(rate); // blink delay 330 LED
output_low(LED); // LED off
delay_ms(rate); // delay before return
}

void main(void)
{
init(); // configure hardware
while(1) // continuous loop
{
set_adc_channel(0);// set a/d channel to gpio.0
delay_us(50); // delay for acquisition
ad = read_adc(); // read a/d into ad variable
Blink(ad); // blink LED at rate set by 10-bit a/d value
}
}

I copied your code into an MPLAB project and it compiled OK with the
PCM compiler. The 12F683.h file has the #device statement in it for
the PIC. It's near the top of the file and looks like this:

If you right click on the <12F683.h> and select 'Open file at cursor', does the file open? If it doesn't then you really haven't specified a device.

It's a 10 bit adc so that line is superfluous unless you want to right or left shift it. (default is left shifted in 16 bits.) What happens if you comment it out. Perhaps removing it will give a different error and help find the problem.

[micro17]

yes, i delete "#device adc = 10"
now i get error at line 1 "Too many nested #INCLUDEs"


Thank you very much for responses..

Is the code that you posted really the exact same file that you are
trying to compile ?

[micro17]

yes, is identical
I guess not specified the device.....why?

Somehow, I feel that you have edited the CCS file, 12F683.h.
Make sure that file doesn't have any #include statements in it.
You should be using the official, unedited, CCS file in this directory:
