Other Parts Discussed in Thread: CC2540
hello community,
please dont kill me :) i think (hope) this is a little problem, but it drives me crazy for 2 days...
i am very new in c programming. i use the cc2540.
in the first time i only use the cc2540 as a "normal" µC. i will use the blutooth thing when the love grows bigger. this is our third date :-)
this is the evalboard i use. its from bluegiga. there was a script-language included, but i killed it with TI cc debugger.
i am using IAR to programm this lady, but she is very strinct and does not forgive any mistakes.
i am trying to build a function to set up delays. milliseconds in this case.
she is complaining about that she expected any expressions. but i dont understand why.
here is my little programm.
#include <iocc2540.h>
void delay_ms(int ms)
#define timertick = ms
{
IEN0 = 0x80; // alle interrupts enablen
TIMIF = 0x40; // enable overflow interrupt
T1CTL = 0x40; // divider einstellen 1/8
T1CC0L = 0x60; // low byte
T1CC0H = 0xF0; // high byte
T1STAT = 0x20; // wird gesetzt wenn wert erreicht
T1IE = 0x02; // Timer 1 interrupt enable
T1CTL = 0x02; // start in Modulo mode
while(timertick > 0); <-- here
}
volatile unsigned char delay=0;
#pragma vector=0x4b
__interrupt void Timer1_overflow(void)
{
if (timertick > 0); <-- here
timertick=--; <-- here
}
i hope you can help us to let our love grow :-)
thanks mathias
