Kjansen45 | 0:689817250cb6 | 45 | The SDP connector is a 120 pin connector used on Analog Devices controller |
Kjansen45 | 0:689817250cb6 | 46 | boards to interface with ADI evaluation boards, over 450 ADI evaluation boards |
Kjansen45 | 0:689817250cb6 | 47 | utilise this connector, a list of these boards can be found at |
Kjansen45 | 0:689817250cb6 | 48 | https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-development-platforms/sdp.html#Compatible-Boards. |

Kjansen45 | 0:689817250cb6 | 50 | The following is an example program showing how to initialise and use SDP |
Kjansen45 | 0:689817250cb6 | 51 | connector peripherals (using SPI and GPIOs as an example) on the SDP-K1 in mbed. |
Kjansen45 | 0:689817250cb6 | 52 | Informtion on the pin name definitions for the SDP connector on the SDP-K1 can |
Kjansen45 | 0:689817250cb6 | 53 | be found at https://os.mbed.com/platforms/SDP_K1/. |
Kjansen45 | 0:689817250cb6 | 54 | The full list of peripherals available on the SDP connector include GPIOs, |
Kjansen45 | 0:689817250cb6 | 55 | Timers, SPI, I2C, and UART. For further information on how to enable these |
Kjansen45 | 0:689817250cb6 | 56 | peripherals, consult the mbed documentation https://os.mbed.com/docs/mbed-os/v5.15/apis/drivers.html |
