Mt6701 Example

This example shows the use of the Mt6701 component to communicate with a MT6701 magnetic encoder chip.

How to use example

It uses the task component to periodically read the raw count, position, and velocity of the encoder, the filters component (specifically the espp::ButterworthFilter class) to filter the raw values from the sensor, and the format component to print the data to the console in CSV format.

Hardware Required

This requires a MT6701 magnetic encoder dev board with an diametric magnet and the MT6701 dev board should be connected to the ESP dev board you choose via I2C.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

Example Output

Here is some example output plotted using the uart serial plotter:
