Header files are useless without the Devices.dat file.

hello

i downloaded the ccs demo when i am compiling this programm its shows that p16c84.h Unknown Device Type in the Devices folder i have only p15c84 when i use this then also its displaying the same thing so i just putted 16F877A.h header file this is my code

#include <16F877A.h>

#USE DELAY( CLOCK=4000000 ) /* Using a 4 Mhz clock */

#FUSES XT,NOWDT,NOPROTECT,NOPUT
/* Use XT mode, No Watch Dog, No Code Protect, No Power-up Timer */

#byte port_b=6 /* define the location of register port_b */
#byte port_a=5 /* define the location of register port_b */

char const pat[34]={0x7F,0x08,0x08,0x08,0x7F,0x00,0x7F,0x49,0x49,0x41,0x41,0x00,0x7F,0x01,0x01,0x01,0x01,0x00,0x7F,0x01,0x01,0x01,0x01,0x00,0x3E,0x41,0x41,0x41,0x3E,0x00,0x00,0x00,0x00,0x00};

main(){
char cnt, cnt2, scrollcnt, col;

set_tris_b(0); /* set port_b as outputs */
set_tris_a(0); /* set port_a as output */

port_b = 0; /* ZERO port_a & port_b */
port_a = 0;

scrollcnt = 0;
cnt2 = 0;
while(1) // Infinite loop to avoid run on code
{
col = 0b00000001; // The column that we are driving
++scrollcnt; // scrollcnt is used as a delay before we switch columns
if (scrollcnt == 250)
{
scrollcnt = 0;
++cnt2;
if (cnt2 == 34)
cnt2 = 0;
}

for(cnt = 0;cnt < 5;cnt++)
{
port_a = 0; // Turn off any previous data displayed
port_b = pat[cnt+cnt2]; // Setup the data to display
port_a = col; // Display the new data

delay_ms(1); // Give some delay before we output the next column

col<<=1; // Rotate our mask for the next column
}
}
}

so i think that may be i need those header files can u explain me pls

thank for the reply

The demo, only supports the 16F877, 16C544, and the 18F458. Adding the header files, _will not change this_. If you wan't to compiler for the 16C84, then I'm afraid you will have to buy the compiler.

Hello telmah

thank for the info i don't no about this i am trying to compile for long time coz i have P16PRO programmer and picallw and winicprog not support 16f877 chip so i changed the code to fit in 16f6282 but its not compiling unless i change the header file to 16f877 any way in demo its not support as my intension is to design the moving message display i have the code but i don't no how to design the circuit

thanks for ur reply

Here you can read about the limitations of the demo version:

hello haplo

yes i seen the limitations i think i have to purchase the ccs c compiler i don't no much about c and new to embeded as i want to build the 5 of 5x7 dot matrix moving message for that reason only coz i have only pic16f628 and pic16f84a the p16pro and picallw not support other chips so i am struck i seen the code of moving message so i tried to compile in 628 its not compiling

anyway thanks for ur info
