Dependencies: LCD Menu ButtonCtrl TimeManagement EventLog AddressMap emic2
ESCM 2000 Control and Display application provides interface for the LPC1768 processor boards with the ECSM 2000 system.
This application implements SW interface : - RX 485 Receive from physical system - RX 485 Interface to send toECOM / ESCM board - CAN Interface to send to ECOM / ESCM board - 4x40 LCD with menu controls - RTC configuration -EMIC2 Sound Card - GPIO Extender to push buttons etc
