TMDX570LC43, communication protocol between PC and board

Konstantin Sukharev

Other Parts Discussed in Thread: TMDX570LC43HDK, HALCOGEN

We have TMDX570LC43HDK

I ran Hercules Safety MCU Demos example. It works properly.

I cannot find communication protocol description between PC and board, register map. I use USB (virtual COM) port.

Are there information about communication protocol between PC and board, register map for Hercules Safety MCU Demos example?

It sets the virtual com port to 9600 baud and uses 8 bit data:

Hi Bob Crosby!

Thanks for reply!

Comport works with following parameters:

Baud: 19200

data bits: 8

stop bit: 1

parity: non

I still did not find protocol description and board register map.

I don't think the protocol is documented, but you should have the source. It is in a directory like:
C:\ti\Hercules\Hercules Safety MCU Demos\4.0.0\TMS570LC43x_target_sources\HALCoGen\source (depending on the install directory).

You can see how the command from the PC is interpreted in the function sciNotification() in the file HL_notification.c.

Not sure I know what you mean by "board register map".
