# nRF52 Port
|
||||
|
||||
WIP
|
||||
|
||||
## requirements
|
||||
|
||||
- GNU make
|
||||
- ARM GCC for embedded development
|
||||
- JLink Segger command line tools
|
||||
- Download and unzip the Nordic SDK 11 under `nordic/`
|
||||
|
||||
|
||||
## quickstart
|
||||
|
||||
Plug your board and type:
|
||||
|
||||
$> make flash-all
|
||||
|
||||
|
||||
## debugging
|
||||
|
||||
$> make gdbserver
|
||||
|
||||
in another terminal
|
||||
|
||||
$> make gdb
|
||||
|
||||
in yet another terminal (for the RTT messages)
|
||||
|
||||
$> telnet 127.0.0.1 19021
|
||||
|
||||
|
||||
## TODO
|
||||
|
||||
- BLE peripheral
|
||||
- Advertisement
|
||||
- Manage services/characteristics
|
||||
- Notifications/Indications
|
||||
- HAL
|
||||
- UART
|
||||
- TWI
|
||||
- SPI
|
||||
- ADC
|
||||
- Flash
|
||||
- GPIO
|
||||
- I2S
