    Therefore, you need to use the real-time debugging tool to monitor the status of the running motor. The BCP is a very useful and convenient real-time debugging tool provided by Cypress to monitor the motor state in the debugging process. This section introduces how to configure and use the BCP in real-time debugging for the motor control application.

  • Page 71: Bcp Monitoring Overview

    The first step in monitoring data on the BCP is to set up the hardware and install the driver program for the USB-to-UART bridge controller (CY7C65213) on CY8CKIT-037. Connect the USB cable to CY8CKIT-037 at connector J11. Then configure the hardware for the Sensored BLDC Motor Control example project following step1 to step 5 in section 5.2.5.
