### RP2040-based boards

The command to build a chocofi Vial firmware with ProMicro-shaped RP2040 microcontroller boards such as the Sea Picro.

```
qmk compile -kb crkbd/rev1 -km vial -e CONVERT_TO=promicro_rp2040
```

It's recommended to build your own firmware. Here's a precompiled chocofi firmware based on crkbd.

### Firmware for nice!nano wireless boards

The pre-soldered wireless Chocofi keyboard with nice!view are pre-flashed miryoku ZMK firmware.

The pre-flashed firmware:

Left Board
{% endfile %}

{% file src="/files/uauvkTnb6bk6jWqD3Cl2" %}
Right Board
{% endfile %}

If you would like to customize your own keymap, please refer to the [ZMK documentation](https://zmk.dev/docs/user-setup). You can find an example of the firmware at the following link: [ZMK Config Corne Chocofi with Niceview](https://github.com/beekeeb/zmk-config-corne-chocofi-with-niceview/tree/main).

#### Troubleshooting 1: My nice!view doesn't display any graphics after flashing a custom firmware. 

To resolve the issue of the nice!view not displaying graphics after flashing a custom firmware, you will need to enable the `nice_view` and `nice_view_adapter` features in your custom ZMK firmware.

Example: <https://github.com/beekeeb/zmk-config-corne-chocofi-with-niceview/blob/main/build.yaml>

```yaml
include:
  - board: nice_nano_v2
    shield: corne_left nice_view_adapter nice_view
  - board: nice_nano_v2
    shield: corne_right nice_view_adapter nice_view
```
