MPU Unit Test

Structure:

• mpu-tests contains the tests themselves.
• unit-test-app is the project to flash and run the tests. Command: make flash monitor. Works the same as the default unit-test-app from esp-idf.

There is a test configuration menu [MPU test config] in menuconfig -> component config, to setup the connection pins, speed, etc.

Note:

Before trying to build the unit-test-app, add the I2Cbus/SPIbus library path to EXTRA_COMPONENT_DIRS in the unit-test-app/Makefile.

The mpu tests also work with the default unit-test-app from esp-idf. If you 'unit-test' from there, do not forget to add the MPU component path as well as MPU/test/mpu-tests directory to EXTRA_COMPONENT_DIRS in the Makefile. (and the above dependencies).

See Unit Testing in ESP32 for more information.

Current tests:

1. basic test
2. sample rate measurement
3. max sample rate test
4. low power accelerometer mode
5. interrupt configuration
6. basic auxiliary I2C configuration
7. slave 4 transfers
8. external frame synchronization (FSYNC pin)
9. sensor data test
10. standby mode
11. FIFO buffer
12. offset test
13. self-test check
14. motion detection and wake-on-motion mode
15. free-fall detection
16. zero-motion detection
17. compass configuration
