CCS3.3--28335编程,求解释~
是不是CCS3.3编程环境是分大小写的?因为在main里面有一个自己写的interrupt void xint3_isr(void)
而在DSP2833x_DefaultIsr.c
里面又有一段
interrupt void XINT3_ISR(void)// External Interrupt
{
// Insert ISR Code here
// To receive more interrupts from this PIE group, acknowledge this interrupt
// PieCtrlRegs.PIEACK.all = PIEACK_GROUP12;
// Next two lines for debug only to halt the processor here
// Remove after inserting ISR Code
asm (" ESTOP0");
for(;;);
}
请问,ccs3.3是区分大小写的对吗?
否则的话这两个中断isr不是会产生冲突吗?~
求前辈们解释~~thanks 光写中断处理没用,还要挂到中端向量表上啊,你挂哪个处理函数就运行哪个了。 回复【1楼】tedden

谢谢您!
我明白了
中断向量表里面的中断ISR入口地址寄存器赋值为我自己定义的中断服务函数首地址,代码如下
InitPieVectTable();
// Interrupts that are used here are re-mapped to ISR functions found within this file.
EALLOW; // This is needed to write to EALLOW protected registers
PieVectTable.XINT3 = &xint3_isr;
PieVectTable.XINT4 = &xint4_isr;
EDIS; // This is needed to disable write to EALLOW protected registers
