This is a modified copy of the SparkFun Arduino library for the TDK InvenSense ICM-20948 Inertial Measurement Unit 9-Degree Of Freedom sensor from [SparkFun_ICM-20948_ArduinoLibrary](https://github.com/sparkfun/SparkFun_ICM-20948_ArduinoLibrary). It bases on the Portable C99 code and uses the I2C and SPI driver of ESP-IDF. The code bases on Version 1.3 of the SparkFun Arduino library and  includes support for the InvenSense Digital Motion Processor (DMP™). You can find further details in [DMP.md](docs/DMP.md).

## Supported Features

* I2C

* SPI

* DMP

## Using component

```bash

idf.py add-dependency "cybergear-robotics/icm20948"

```

## Example

Not all examples are ported. For further examples, please look at the original project.

1. create example project

```bash

idf.py create-project-from-example "cybergear-robotics/icm20948:i2c_agmt"

```

2. Go to to example directory (for example `spi_agmt`)

   `cd spi_agmt`

3. Set ESP chip

   `idf.py set-target esp32`

4. Configure ICM-20948 settings

   `idf.py menuconfig` and go to `ICM-20948 Example`

5. Build, flash

   `idf.py build flash monitor`

## DMP Support

DMP support can be enabled in menuconfig "ICM-20948 Settings". An example is provided in `examples/spi_dmp_quad9_orientation`.
