# Supporting your particular board

## Using a 'normal' PC
|
|
|
|
* Did you tell your PC it had a mouse plugged in?
|
|
* Did you tell it what I/O address the video card was located at?
|
|
* No! It auto-discovers all of these things.
|
|
* USB, PCI-Express, SATA all have "plug-and-play"
|

## Using an Embedded System
|
|
|
|
* There is no plug-and-play
|
|
* Your MCU can put different functions (UART, SPI, etc) on different pins
|
|
* The choice of which function goes on which pin was decided by the PCB designer
|
|
* You now have to tell the software how the PCB was laid out
|
|
* i.e UART0 TX is on Port 0, Pin 13

## Board Support Crates
|
|
|
|
* You can wrap this up into a Board Support Crate
|
|
* Especially useful if you are using a widely available dev-kit
|
|
* e.g. the nRF52840-DK, or the STM32 Discovery
|
|
* Still useful if the board design is an in-house one-off
|
|
* Create the drivers and does the pin assignments for you
|
|
* Helps make your application portable across different boards
