Hi all. I want to use all 4 T0MRx in my program. whit TxMCR we can set what happen after T0MRx match with T0TC. my problem is here : I could wrote code for 1 T0MRx , but I can't write code for all of them.
one point : timerx jast have one isr , how i can use all of 4 T0MRx interrupt ? thanks.
oh , the MCU is lpc2378.
i could wrote a code , but it didn't work.
And it really didn't occur to you that
a) you'll not just have to write code, but also show it to people, if they're to have any chance at helping you, nor that
b) "it didn't work" is an utterly useless way of describing any error
?
it's my code :
#include <lpc23xx.h> #define LCD_PORT_0 #define LCD_RS 25 #define LCD_E 24 #define LCD_DB4 23 #define LCD_DB5 22 #define LCD_DB6 21 #define LCD_DB7 20 #include <lcd.h> int i=0; int j=10000; void timer0_isr(void) __irq{ if(T0MR0==T0TC) i++; else if(T0MR1==T0TC) j--; T0IR=3; VICVectAddr=0; T0TCR=1; } int main(){ SCS=1; lcd_init(); lcd_clear(); //timer0 setting T0TCR=2; // reset counter , disable counter T0CTCR=0; // set T/C for Timer T0PR=0; // no prescale T0MR0=1500000; T0MR1=3000000; T0MCR=63; T0TCR=1; //enable counter //interrupt setting VICIntSelect=0; // set timer0 interrupt on IRQ mood VICIntEnable=1 << 4; // enable interrupt for timer0 VICVectAddr4=(unsigned long) timer0_isr; //set label for jump when T0MR0 is match with T0TC //LEDs setting PINSEL6=0; FIO3DIR0=255; //main loop while(1){ lcd_gotoxy(1,1); lcd_puts(i); lcd_putsf(" "); lcd_gotoxy(2,1); lcd_puts(j); lcd_putsf(" "); }}
