+/**
+ * @file dcdcmbus.ino
+ * @brief usage of XY6020L DCDC for simple max power point tracking of 
+ *  a solar module driving a electrolytic cell
+ *  Cells voltage start from ~3 V and current will rise up to ~3A at 4 V.
+ *  At ~19 V the 20V pannel has its maximum power.
+ *  Simple I-controler increases the cell voltage till the power consumption
+ *  from the solar panel drives its voltage below 19 V.
+    Hardware:  Arduino Pro Micro Clone from China
