TID=12027&P=47#212592latest version serial LCD

it seemed to do an extra MPPT scan every couple of mins at the 55sec mark ,but i spotted this in the code:

if ( timeout_check(8,1))
   {
     cal_sensor_count ++;
     if (cal_sensor_count > 1)           // should be 60 for an hour. testing will have it at 2 or something
       {
         cal_sensor_count = 0;           // one hour is up time to recal current sensor zero points
         if (track_mode != NIGHT)
           {
             //stop it


But as the Comment says "should be 60 for an hour" so is easy enough to change.


it's an easy fix alright. Thanks for reading through the code and finding this.

latest version with the fix:
