+ *
+ * @param[in] input1: input array 1
+ * @param[in] input2: input array 2
+ * @param output: output array
+ * @param len: amount of operations for arrays
+ * @param step1: step over input array 1 (by default should be 1)
+ * @param step2: step over input array 2 (by default should be 1)
+ * @param step_out: step over output array (by default should be 1)
+ *
+ * @return
+ *      - ESP_OK on success
