MCT8316AEVM: LED D6 of MCT8316AEVM

Part Number: MCT8316AEVM
Other Parts Discussed in Thread: MCT8316A

Hi,

For LED D6, changing the Baud Rate of serial communication will change the way it shines. I would appreciate it if you could tell me what each of them shows.

When the recommended Baud Rate is 9600bps, it blinks at 1s intervals, but at other times it turns on and off.

Thanks,

Astro

  • Hi Astro, 

    Thanks for posting to the e2e motor driver forum. 

    Our team will take a look at the question above & aim to provide an answer by end of week

  • Hi, Andrew

    Thank you for your reply! Do you have any update?

  • Hi Astro,

    The LED D6 will toggle on/off every time the MSP430 receives an UART byte from the PC/GUI.

    • When the EVM is simply connected to the GUI (with no on-going register read/write), the GUI sends out periodic pings at 1s interval to the EVM to detect if the EVM is still connected/disconnected. Therefore, LED D6 blinks at 1s interval.
    • When the GUI sends read/write commands to the MCT8316A, LED D6 will blink at whatever speed the MSP430 interface is receiving read/write commands from the GUI.

    Also, please note that the band rate is configured to 9600 in the MSP430 firmware on the EVM, therefore, the GUI has to configure to 9600 as well. If you change the baud rate on the GUI, you will need to modify the MSP430 firmware to match the new baud rate.

    Thanks,
    Eric C.
