This manual introduces the EDP-CM-mbed adapter board, which is used to connect the mbed command module to different power supplies and interfaces.
The EDP-CM-mbed adapter module is designed to remap the pinout of the mbed development module to that of the RS-EDP platform. It acts as a Command Module (CM) within the system, dictating whether the whole system operates at 3.3V or 5.0V based on its internal microprocessor voltage.
The adapter board includes features such as a mini SD Card interface and an SPI serial connection for a small graphics LCD. It comes with low-level drivers to communicate with other modules in the RS-EDP system, including analogue, digital I/O, communications, and motor drive modules. The manual details various solder link options that allow users to configure the board for different functions.
The adapter board is designed to remap the pin out of the mbed module to that of the RS-EDP platform.
The module uses a 3.3V microprocessor and consequently the I/O is mostly 3.3V.
The Vcc_CM line on the base board is connected to 3.3V by the track on the adapter board.
