I am using the below code for ADC on ts7800 , but I am getting 0 output, I think it is because of port address can anybody help me in this regards as I am not able to find the correct port address. CODE #include<unistd.h> #include<sys/types.h> #include<sys/mman.h> #include<stdio.h> #include<fcntl.h> #include<assert.h> int main(int argc, char **argv) { volatile unsigned short * complete; volatile unsigned char * lsb, * msb, * control; int res; int fd = open("/dev/mem", O_RDWR); assert(fd != -1); lsb = control = (unsigned char *)mmap(0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0x10c00000); msb = lsb + 1; complete = (unsigned short *)mmap(0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0x10800000); *control = 0x41; while ((*complete & 0x80) == 0); res = *lsb; res |= *msb << 8; printf("result: %d\n", res); close(fd); return 0; } OUTPUT lsb: 1073731936 msb: 1073731937 complete:1073840128 *complete:0 *control:0 result:0 __._,_.___
