+The SDP connector is a 120 pin connector used on Analog Devices controller 
+boards to interface with ADI evaluation boards, over 450 ADI evaluation boards 
+utilise this connector, a list of these boards can be found at 
+https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-development-platforms/sdp.html#Compatible-Boards.
+
+The following is an example program showing how to initialise and use SDP 
+connector peripherals (using SPI and GPIOs as an example) on the SDP-K1 in mbed.
+Informtion on the pin name definitions for the SDP connector on the SDP-K1 can 
+be found at https://os.mbed.com/platforms/SDP_K1/.
+The full list of peripherals available on the SDP connector include GPIOs, 
+Timers, SPI, I2C, and UART. For further information on how to enable these 
+peripherals, consult the mbed documentation https://os.mbed.com/docs/mbed-os/v5.15/apis/drivers.html
