# nrf51-sdk
|
||||
Module to contain files provided by the nordic nRF51 SDK
|
||||
|
||||
The latest version of this module uses files from Nordic SDK 8.1.0. The files are extracted from: https://developer.nordicsemi.com/nRF51_SDK/nRF51_SDK_v8.x.x/nRF51_SDK_8.1.0_b6ed55f.zip
|
||||
|
||||
## Changes made to Nordic files
|
||||
The files are kept the same as much as possible to the Nordic SDK. These minor modifications are made in order to integrate with mbed:
|
||||
|
||||
1. Add `#define asm __ASM` to the top of [nrf_delay.h](https://github.com/ARMmbed/nrf51-sdk/blob/master/source/nordic_sdk/components/drivers_nrf/hal/nrf_delay.h). Because all yotta mobules compile with -std=c99 which does not include "asm" keyword.
|
||||
1. Add `#define BLE_STACK_SUPPORT_REQD` to the top of [ble_stack_handler_types.h](https://github.com/ARMmbed/nrf51-sdk/blob/master/source/nordic_sdk/components/softdevice/common/softdevice_handler/ble_stack_handler_types.h).
|
||||
1. Add this patch to [nrf_svc.h](https://github.com/ARMmbed/nrf51-sdk/blob/master/source/nordic_sdk/components/softdevice/s130/headers/nrf_svc.h)

## Porting new versions of Nordic SDK
|
||||
A list of files currently requierd by mbed is maintained in [script/required_files.txt](https://github.com/ARMmbed/nrf51-sdk/blob/master/script/required_files.txt). [A python script](https://github.com/ARMmbed/nrf51-sdk/blob/master/script/pick_nrf51_files.py) is written to help porting from nordic sdk releases. **required_files.txt** is parsed to find a list of filenames. The script searches for these filenames in the sdk folder, and copy then into the yotta module mirroring the folder structure in the sdk. **extraIncludes** is automatically added to module.json to allow direct inclusion of noridc headers with just he filename.
|
||||
|
||||
### Script usage
|
||||
```
|
||||
python pick_nrf51_files.py <full-noridc-sdk-path> <nrf51-sdk-yotta-module-path>
|
||||
```
