|
* @brief Support for the SenseBox MCU with SAMD21 board.
|
|
|
|
### General information
|
|
|
|
[SenseBox](https://www.sensebox.de/) is a do-it-yourself kit for stationary
|
|
and mobile sensor stations.
|
|
|
|
SenseBox board is based on the Atmel SAMD21G18A microcontroller. See
|
|
@ref cpu_samd21.
|
|
|
|
|
|
### Flash the board
|
|
|
|
1. Put the board in bootloader mode by double tapping the reset button.<br/>
|
|
When the board is in bootloader mode, the user led (red) oscillates smoothly.
|
|
|
|
|
|
2. Use `BOARD=sensebox_samd21` with the `make` command.<br/>
|
|
Example with `hello-world` application:
|
|
```
|
|
make BOARD=sensebox_samd21 -C examples/hello-world flash
|
|
```
|
|
|
|
### Accessing STDIO via UART
|
|
|
|
To access the STDIO of RIOT, a FTDI to USB converted needs to be plugged to
|
|
the UART/Serial 1 pins on the board.
|
|
|
|
### On I2C port
|
|
I2C port is enabled by default. To disable it use ```I2C_DISABLE```. To
|
|
re-enable use ```I2C_ENABLE```.
|
|
|
|
### On XBEE ports
|
|
XBEE1 and XBEE2 ports are enabled by default. To disable any of them use
|
|
```XBEEn_DISABLE```. To re-enable use ```XBEEn_ENABLE```.
|
|
|
|
On the board there is a reset circuit for this ports that delays the reset
|
|
signal from the enable signal for about 300ms. Because of that a delay has
|
|
been introduced in the ```board_init``` function, so that any SPI device
|
|
connected to the ports is reset before use.
|
|
|
|
#### SX127X radio
|
|
The pin configuration for the SX127X radio on the
|
|
*boards/sensebox_samd21/include/board.h** file assumes that it will be connected to
|
|
the XBEE1 port. If a different configuraion is needed please modify this
|
|
file.
|
|
|
|
#### SD card
|
|
The pin configuration for the mSD-Bee module radio on the
|
|
*boards/sensebox_samd21/include/sdcard_spi_params.h** file assumes that it will be
|
|
connected to the XBEE2 port. If a different configuraion is needed please
|
|
modify this file.
