How to convert array of chars to array of ints?

If you have a C string containing ASCII numbers with a common delimiter (comma in this case) you can use the strtok() function to split it into individual strings. Then you can use atoi() to convert those individual strings into integers:

char array[] = "10,11,12,1,0,1,0";
int intArray[7]; // or more if you want some extra room? 

int ipos = 0;
// Get the first token from the string
char *tok = strtok(array, ",");
// Keep going until we run out of tokens
while (tok) {
    // Don't overflow your target array
    if (ipos < 7) {
        // Convert to integer and store it
        intArray[ipos++] = atoi(tok);
    }
    // Get the next token from the string - note the use of NULL
    // instead of the string in this case - that tells it to carry
    // on from where it left off.
    tok = strtok(NULL, ",");
}

Note that strtok() is a destructive function. It will decimate your existing string with NULL characters as it slices it up.
