# Setup
|
||||
|
||||
The `Electronut Labs Papyr` board is based on the `nRF52840` SoC from
|
||||
Nordic Semiconductors. It has an e-ink display on it, along with a CR2477
|
||||
battery holder.
|
||||
|
||||
Papyr can be programmed with the [`Adafruit nRF52 bootloader`](https://github.com/adafruit/Adafruit_nRF52_Bootloader) to
|
||||
|
||||
Schematic, datasheet default pin mapping etc. can be found over [here](https://docs.electronut.in/papyr/). The default pin mapping can be found in the board directory.
|
||||
|
||||
## Installing CircuitPython submodules
|
||||
|
||||
Before you can build, you will need to run the following commands once, which
|
||||
will install the submodules that are part of the CircuitPython ecosystem, and
|
||||
build the `mpy-cross` tool:
|
||||
|
||||
```
|
||||
$ cd circuitpython
|
||||
$ git submodule update --init
|
||||
$ make -C mpy-cross
|
||||
```
|
||||
|
||||
## Installing the Bootloader
|
||||
|
||||
If the `Adafruit nRF52 bootloader` is installed on the board, then the
|
||||
bootloader allows you to update the core CircuitPython firmware and internal
|
||||
file system contents using serial, or USB CDC, or USB mass storage.
|
||||
|
||||
On empty devices, the bootloader will need to be flashed once using a
|
||||
HW debugger such as a Segger J-Link, or Blackmagicprobe
|
||||
(or [Electronut labs Bumpy](https://docs.electronut.in/bumpy/)).
|
||||
|
||||
|
||||
## Building and Flashing CircuitPython
|
||||
|
||||
No special notes for this, follow `ports/nrf` generic `README.md`.
|
||||
|
||||
### Flashing CircuitPython with MSC UF2
|
||||
|
||||
`uf2` file is generated last by `all` target.
|
||||
|
||||
```
|
||||
$ cd ports/nrf
|
||||
$ make V=1 SD=s140 SERIAL=/dev/ttyACM0 BOARD=electronut_labs_papyr all
|
||||
...
|
||||
...
|
||||
python3 ../../tools/uf2/utils/uf2conv.py -f 0xADA52840 -c -o "build-electronut_labs_papyr-s140/firmware.uf2" build-electronut_labs_papyr-s140/firmware.hex
|
||||
Converting to uf2, output size: 536576, start address: 0x26000
|
||||
Wrote 536576 bytes to build-electronut_labs_papyr-s140/firmware.uf2
|
||||
```
|
||||
|
||||
Simply drag and drop firmware.uf2 to the MSC, the nrf52840 will blink fast and reset after done.
|
||||
|
||||
### Other tips
|
||||
|
||||
Once circuitpython is running on your board, it will come up as a mass storage
|
||||
device named `CIRCUITPY`, where you can drop in your python code. The file names
|
||||
it looks for are `main.py`, `main.txt`, `code.py` or `code.txt`.
