本人使用ICD2调试30F3012,软件为MPLAB7.50,C30 V1.20
项目中添加的链接文件为p30f3012.gld,
#include "p30f3012.h"
unsigned int T1Buffer[16],T2Buffer[16];
unsigned int WPointer;
unsigned char over;
void testport(void);
void timer1_init(void);
nt main(void)
{ /* pc = 0x180 */
/*
unsigned int xdata[512];
union xx{
unsigned char v1[2];
unsigned int v2;
}utest;
*/
unsigned int i,step;
unsigned int y;
/* variable init */
WPointer = 0;
over = 1;
for(i=0;i<16;i++)
{
T1Buffer = i;
T2Buffer = i;
}
/* port init */
testport();
/* timer init */
timer1_init();
while(over);
while(1);
}
void __attribute__((__interrupt__)) _T3Interrupt(void)
{
IFS0bits.T3IF = 0;
T1Buffer[WPointer] = TMR1;
T2Buffer[WPointer] = TMR2;
WPointer++;
T1CONbits.TON = 0;
T2CONbits.TON = 0;
TMR1 = 0;
TMR2 = 0;
if(WPointer&0x10){
IEC0bits.T3IE = 0;
T1CONbits.TON = 0;
over = 0;
}
else{
T1CONbits.TON = 1;
T2CONbits.TON = 1;
}
return;
}
void timer1_init(void)
{
T1CON = 0x0002;
TMR1 = 0x0000;
PR1 = 0xffff;
T2CON = 0x0002;
TMR2 = 0x0000;
PR2 = 0xffff;
T3CON = 0x0000;
TMR3 = 0x0000;
PR3 = 0x2710;
/* period = 1.25ms */
IPC1bits.T3IP = 0x4;
IPC1bits.T2IP = 0x0;
IPC0bits.T1IP = 0x0;
IEC0bits.T3IE = 1;
T3CONbits.TON = 1;
T1CONbits.TON = 1;
T2CONbits.TON = 1;
}
调试发现T1Buffer and T1Buffer 均为restricted memory
中断中对 T1Buffer and T1Buffer操作无效
我在microchipmplab idedev的文件夹中dspic30f3012e.dev中的第39行有
UnusedRegs (0x800-0x13ff)
在dspic30f3012e.dev中没有发现0x800以上的限制阿
如果我用MPLAB SIM来仿真则没有任何问题
请教各位大虾，如何解决阿？？？？？？ |
