This repository contains firmware for streaming up to 6-axes IMU data over UART from the PIC24FJ128GA705 PIC-IoT WG development board with Mikroe IMU2 Click board, streaming using one of several formats as described in the sections below.
This project is a port of the SAMD21 ML Eval Kit data logger maintained on github; please see that repository for more detail and instructions. Below are a summary of the functional differences between the 2 projects:
- PIC-IOT WG DEVELOPMENT BOARD (AC164164)
- IMU 2 click board (https://www.mikroe.com/6dof-imu-2-click)
- MPLAB® X IDE (https://microchip.com/mplab/mplab-x-ide)
- MPLAB® XC16 compiler (https://microchip.com/mplab/compilers)
- MPLAB® Code Configurator (https://www.microchip.com/mcc)
- PIC24FJ128GA705 Product Family Page
The data streamer firmware will output sensor data over the UART port with the following UART settings:
- Baudrate 115200
- Data bits 8
- Stop bits 1
- Parity None
| Sensor Type | MPLAB X Project Configuration Selection |
|---|---|
| Bosch BMI160 IMU | DSPIC33CK_CURIOSITY_BMI160 |
| TDK ICM42688 IMU | DSPIC33CK_CURIOSITY_ICM42688 |
To select the data streaming format, set the DATA_STREAMER_FORMAT macro in app_config.h to the appropriate value as explained in the table below.
| Streaming Format | app_config.h Configuration Value |
|---|---|
| ASCII text | #define DATA_STREAMER_FORMAT DATA_STREAMER_FORMAT_ASCII |
| MPLAB Data Visualizer stream | #define DATA_STREAMER_FORMAT DATA_STREAMER_FORMAT_MDV |
| SensiML Simple Stream | #define DATA_STREAMER_FORMAT DATA_STREAMER_FORMAT_SMLSS |
High level sensor parameters like sample rate and axes selection can be configured by modifying the macro values defined in firmware/src/app_config.h. See the inline comments for further description.
