@brief Support for the Serpente board.
|
|||
|
|
|
|||
|
|
### General information
|
|||
|
|
|
|||
|
|
The [Serpente boards](https://serpente.solder.party/) are low-cost development boards designed
|
|||
|
|
to be used with Adafruit’s CircuitPython.
|
|||
|
|
|
|||
|
|
Three versions of the board board exist, but they all the same except for the USB connector.
|
|||
|
|
The standard Serpente board contains a female USB Type-C connector, the Serpente Plug C
|
|||
|
|
contains a male USB Type-C connector, and the Serpente Plug uses the board itself as a Type-A USB plug.
|
|||
|
|
|
|||
|
|
If you are familiar with the Digispark boards, you may notice some similarities.
|
|||
|
|
This fact is of course not incidental, the Serpente boards are inspired by the Digispark,
|
|||
|
|
both in form-factor as well as use-cases. The Serpente boards are meant to be used as quick
|
|||
|
|
and dirty, yet flexible, prototyping tools.

### Flash the board
|
|||
|
|
|
|||
|
|
Use `BOARD=serpente` with the `make` command.<br/>
|
|||
|
|
Example with `micropython` application:
|
|||
|
|
```
|
|||
|
|
make BOARD=serpente -C examples/micropython flash
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
RIOT will automatically trigger a reset to the bootloader, but this only works if RIOT is still
|
|||
|
|
running on the board.
|
|||
|
|
If your application has crashed or got erased, `make flash` will not be able to trigger a bootloader reset.
|
|||
|
|
|
|||
|
|
To manually enter the bootloader, quickly press the Reset button twice.
|
|||
|
|
You know you've successfully entered the bootloader when the LED begins flashing blue.
|
|||
|
|
|
|||
|
|
Sometimes flashing fails and the board gets stuck in the bootloader.
|
|||
|
|
In this case, just run `make flash` again when the device is not busy anymore.
|
|||
|
|
|
|||
|
|
### Accessing STDIO via UART
|
|||
|
|
|
|||
|
|
STDIO of RIOT is directly available over the USB port.
