58.1. SEI Master: Connect BISSC Encoder

58.1.1. Overview

This demo shows SEI interface read BISSC encoder position data and automatically calculate sampling/update delay time, then print related information by uart console.

58.1.2. Configration

  • Two development boards are required, one as the master and one as the slave.

  • Slave sample path is “samples/drivers/sei/slave/bissc”, master is this example.

  • Master’s SEI_CLK pins should bridging master side，and slave’s SEI_CLK pins should bridging slave side.

  • Connect master’s SEI pins DATA_P/DATA_N to slave’s SEI pins DATA_P/DATA_N.

  • Connect master’s SEI pins CLKO_P/CLKO_N to slave’s SEI pins CLKI_P/CLKI_N.

  • Connect master’s GND to slave’s GND.

58.1.3. Running the example

  • When the example runs successfully, the console shows the following log. ST’s value increasing by 1 each sample.
