Recent changes to the [Chirp Arduino SDK](https://developers.chirp.io/docs).

## v3.4.1 (beta)
- Add support for Teensy boards (cortex-m4 hard float build)

## v3.4.0 (18/09/2019)
- All functions have been renamed to `chirp_sdk*` from `chirp_connect*`
- `chirp_sdk_get_heap_usage` has been added. This gives you the current dynamic memory allocated and used at any time by the SDK.

* A digital I2S MEMS microphone (if your board does not contain a microphone)
* A digital I2S amplifier and compatible speaker

See a full list of supported platforms at the [Chirp Developer Hub](https://developers.chirp.io/docs/using-chirp/platforms#arduino)

For receiving data, you will need a digital MEMS microphone. Some boards (for example, the Nano 33 Sense and Microsoft MXChip) already include a MEMS mic so you are good to go. For others, you will need an external mic such as the [SPH0645](https://www.adafruit.com/product/3421) or [ICS-43434](https://www.mouser.co.uk/ProductDetail/TDK-InvenSense/ICS-43434?qs=u4fy%2FsgLU9PAgmWRI7%252BqXA%3D%3D).

For sending data, we recommend using a digital I2S audio output such as the [UDA1334A](https://www.adafruit.com/product/3678) or [MAX98357A](https://www.adafruit.com/product/3006), connected to a compatible speaker.

You can quickly test that your device is receiving chirps by playing some random test signals from the [Developer Hub](https://developers.chirp.io).

To test whether your device is sending chirps OK, we recommend setting up the [Python command-line tools](https://developers.chirp.io/docs/tutorials/command-line) to receive data from the Arduino.

We don't have support for AVR, is this wanted ?

It's a similar idea for samd and cortex-m0plus I think, the IDE sometimes seems to print it as avr architecture so I thought it better to include both...

Oh okay, well AVR micro controllers are not based on arm whilst samd are but if the ide throws some warnings that's better to keep it then
