New KK2.1.5 KK21EVO Flight Controller With Large LCD Second MPU

KK2.1.5 Evolution KK21EVO Flight Controller With Large LCD Second MPU  Compare With KK2.1.5 Description: KK21EVO is an evolution of Hobbyking KK2.1.5,all the firmware of KK2.1.5 can run on this FC, but KK21EVO have larger LCD,a second MPU make KK21EVO support FUTABA S.BUS, SPEKTRUM DSM2,DSMX satellite.JR DMSS satellite direct connection.There is the same main MCU(ATmega644PA) and hardware as KK2.1.5,user can flash all the KK2.1.5's firmware.The second MPU use to convert S.BUS,DSM2,DSMX,DMSS protocol to PWM signal,user also can turn this MPU off so standard PWM receiver can be used. How to use the second MPU of KK21EVO: There is one red and five blue LEDs on the KK21EVO FC board,red LED named "K"connect to the main MCU(ATmega644PA) like the only LED on KK2.1.5,other five blue LEDs connect to the second MPU named "A" "B" "C" "D" "E"from left to right. If only one of five blue LEDs on(other four LEDs off) that mean receiver type of KK21EVO:                                                         TABLE - I                         A B C D E Standard PWM receiver (the second MPU turn OFF)     ¤ - - - - SPEKTRUM DSM2 satellite receiver                                 - ¤ - - - SPEKTRUM DSMX satellite receiver                                 - - ¤ - - FUTABA S.BUS                                                                      - - - ¤ - JR DMSS satellite receiver                                                  - - - - ¤ "¤" mean LED on,"-" mean off.?WORKING MODE?
