i have used a timer 32 bit to generate a timer of 1 sec .
i have kept interrupt type as terminal count.
set vc1 to 8 ,vc2 to 3 ,cpu clock as vc2 giving me clock of 1 Mhz
i have set the period to 1000000 which means it should generate an interrupt every 1 sec.
i have given the output of terminal count to port 0_0 and connected an led to pin 0 of port 0.
the following is the code i have written
my psoc designer uses hi tech compiler
#include // part specific constants and macros
#include "PSoCAPI.h" // PSoC API definitions for all User Modules
#include "timer32.h"
void interrupt timer32_isr(void);
void main()
{
TIMER32_WritePeriod(0xf4240); //equivalent hex of 1000000
TIMER32_WriteCompareValue(0);
TIMER32_EnableInt();
M8C_EnableGInt;
TIMER32_Start();
}
void interrupt timer32_isr(void) @0x00 //as i have hitech compiler so used this way instead of using pragma directive
{
int count=0; //i have connected port 2 pin 0 to an led so it should glow whenever an interrupt gets generated
count++;
PRT2DR=count;
}
I have added
ljmp _timer32_isr
in the file timer32int.asm at the appropriate place these are the messages of error i get when i build the program
: 0: (500) undefined symbols: (error)
_TIMER32_EnableInt(output\timer2.obj) _TIMER32_WritePeriod(output\timer2.obj) _TIMER32_Start(output\timer2.obj) _TIMER32_WriteCompareValue(output\timer2.obj)
HI-TECH C PRO compiler averages 40% less code than this Lite mode
PRO may reduce your program size by 51 bytes
C:\PROGRA~1\CYPRES~1\PSOCDE~1\tools\make: *** [output/timer2.hex] Error 1
timer2 - 1 error(s) 0 warning(s) 05:13:52
i have referred many app notes as well as user module example projects but cant figure out whats wrong .
if any one can help??
