LMX2572EVM: Communication with the board

Part Number: LMX2572EVM
Other Parts Discussed in Thread: USB2ANY

I have built a windows application including the TI HID library and would like to use it to control the LMX2572EVM board using USB via the Reference PRO board.   Therefore I'd like to know the commands that can be sent/received using hid_write and hid_read to control the LMX2572EVM.

    Hi Stephen,

    I am not familiar with HID, but if you use Ref Pro, you can use TICS Pro (GUI) to control the EVM. You can also generate all the register values from this tool and if necessary, export the register settings to your Win application.

    Thanks for your help.  I am using TICS Pro.  And also USB2ANY Explorer which seems easier when setting a single register value.  The question I have is,  knowing which register I want to write and the value I want to write, what to I have to send to Ref Pro to get it to send the required value over the SPI interface.

    Presumably the MSP430 on Ref Pro does some interpretations of the data it receives over USB. The TI hid.dll provides a USB API but I've no idea what data to send.  I have managed to use it to list the available USB devices and to open the Ref Pro.  Now, what is the protocol to communicate with Ref Pro?

    Regards

    Steve

    Hi Stephen,

    The USB2ANY (Ref Pro used the same hardware and software) is developed by the Amplifier team, suggest you make a post in the Amplifier forum to find out the USB communication protocol.
