### RESET pin configuration
|
|
|
|
|
|
|
|
|
|
On many (all?) nrf52dk boards, the reset pin is not configured out-of-the box.
|
|
|
|
|
This means, that simply nothing happens if the RESET pin is pressed. To change
|
|
|
|
|
this, RIOT provides a little tool in `dist/tools/nrf52_resetpin_cfg`.
|
|
|
|
|
|
|
|
|
|
Simply compile, flash, and run that tool on your board, and the reset pin should
|
|
|
|
|
work for the time being.

## Current measurement:
|
|
|
|
|
|
|
|
|
|
There are two pins for current measurement on board. Don't connect these pins
|
|
|
|
|
to GND!. The left pin is at 3.3V level and the right pin is connected to V33.
|
|
|
|
|
Divide the measured voltage between this pins by 22 to get the current.

## Accessing STDIO via UART
|
|
|
|
|
|
|
|
|
|
The STDIO is directly accessible via the USB port. On a Linux host, it's
|
|
|
|
|
generally mapped to `/dev/ttyACM0`.
|
|
|
|
|
|
|
|
|
|
Use the `term` target to connect to the board serial port<br/>
|
|
|
|
|
```
|
|
|
|
|
make BOARD=nrf52dk -C examples/hello-world term
|
|
|
|
|
```
