#include "LPC177x_8x.H" void f1(U8 *ptr); void f2(U8 *ptr); void (*fpTest1[2])(U8 *ptr1)={&f1,&f2}; void (*const fpTest[2])(U8 *ptr1)={&f1,&f2}; U8 b[2][2]={{0,1},{2,3}}; int main(void) { (*fpTest[0])(b[0]); // fpTest[0]=&f2; //(*fpTest[0])(b[0]); (*fpTest[1])(b[1]); } void f1(U8 *ptr) { volatile U8 a=0; volatile U8 b=0; a=*(ptr); b=*(ptr+1); } void f2(U8 *ptr) { volatile U8 a=0; volatile U8 b=0; a=ptr[0]; b=ptr[1]; }
Why does fpTest exist in On-Chip Flash and fpTest1 in SRAM?
