# WolfSSL Example using the OM13076 (LPCXpresso18S37) board
|
||
|
|
||
|
To use, install the NXP LPCXpresso IDE and import the projects in a new workspace.
|
||
|
|
||
|
1. Change names of `LPCExpresso.project` and `LPCExpresso.cproject` files to `.project` and `.cproject`
|
||
|
2. Run LPCXpresso and choose a workspace location.
|
||
|
3. Right click in the project explorer window and choose Import.
|
||
|
4. Under General choose "Existing Projects into Workspace".
|
||
|
5. Under "Select root directory" click browse and select the wolfSSL root.
|
||
|
6. Check the "Search for nested projects" box.
|
||
|
7. Make sure "wolfssl" and "wolfssl_example" are checked under "Projects:".
|
||
|
8. Click finish.
|
||
|
9. Download the board and chip LPCOpen package for your platform.
|
||
|
10. Import the projects. For example "lpc_board_nxp_lpcxpresso_1837" and "lpc_chip_18xx" are the ones for the LPC18S37.
|
||
|
|
||
|
To setup this example to work with different baords/chips you will need to locate the LPCOpen sources for LPCXpresso on the NXP website and import the board and chip projects. Then you will need to update the "wolfssl_example" project properties to reference these projects (C/C++ General -> Paths and Symbols -> References). See the [LPCOpen v2.xx LPCXpresso quickstart guide for all platforms](https://www.lpcware.com/content/project/lpcopen-platform-nxp-lpc-microcontrollers/lpcopen-v200-quickstart-guides/lpcopen-1) for additional information.

## WolfSSL example projects:
|
||
|
|
||
|
1. `wolf_example`. It has console options to run the Wolf tests and benchmarks ('t' for the WolfSSL Tests and 'b' for the WolfSSL Benchmarks).
|
||
|
|
||
|
## Static libraries projects:
|
||
|
|
||
|
1. `wolfssl` for WolfSSL. The WolfSSL port for the LPC18XX platform is located in `IDE/LPCXPRESSO/lpc_18xx_port.c`. This has platform specific functions for `current_time` and `rand_gen`. The `WOLF_USER_SETTINGS` define is set which allows all WolfSSL settings to exist in the `user_settings.h` file (see this file for all customizations used).

||
|
|
||
|
## Important Files
|
||
|
|
||
|
1. `IDE/LPCXPRESSO/user_settings.h`. This provides a reference for library settings used to optimize for this embedded platform.
|
||
|
|
||
|
2. `IDE/LPCXPRESSO/lpc_18xx_port.c`. This defines the required time and random number functions for the WolfSSL library.
|
||
|
|
||
|
3. `IDE/LPCXPRESSO/wolf_example/wolf_example.c`. This shows use of the WolfSSL tests and benchmarks.
