如何把字符串数据转换成uint16_t数据

f85797

比如我想传个字符串string_data = "{4052,3986,502,2014,500,2014}" 进来

，并且把这个字符串转换成 uint16_t rawdata[6] = {4052,3986,502,2014,500,2014};
应该如何实现呢？

  uint16_t count;
  uint16_t *code_array;
  String tmp_str;

  // Remove the leading "1:1,1," if present.
  if (str.startsWith("1:1,1,"))
    tmp_str = str.substring(6);
  else
    tmp_str = str;

  // Find out how many items there are in the string.
  count = countValuesInStr(tmp_str, ',');

  // Now we know how many there are, allocate the memory to store them all.
  code_array = newCodeArray(count);

  // Now convert the strings to integers and place them in code_array.
  count = 0;
  uint16_t start_from = 0;
  int16_t index = -1;
  do {
    index = tmp_str.indexOf(',', start_from);
    code_array[count] = tmp_str.substring(start_from, index).toInt();
    start_from = index + 1;
    count++;
  } while (index != -1);
