LDC1101EVM: COM port protocol

Hello Oba, 

Sorry you are having this issue. Can you confirm a couple things for me so we can work to resolve this: 

• Does the EVM work with the GUI as expected? 
• Have you performed any software updates on the EVM board? 
• Can you share a snippet of your code where you are communicating to the EVM? 

Thank you, 

Justin Beigel

Hello Justin,

• Does the EVM work with the GUI as expected? 

Yes, it works well.

• Can you share a snippet of your code where you are communicating to the EVM? 

I'm using an RS232 terminal software which is PuTTY.

Hello Oba, 

Thank you for the information. When you send the "02316B" command, do you get any response at all? 

Have you tried using any other commands like reading a register from the device? If you try the "0620" does the data streaming start? 

When you send "1" it only returns the "FFFFFFFFFFFFFFFF" because this is not a valid command. 

Thank you, 

Justin Beigel

Hello Justin,

When I send the "02316B" in ASCII format, I just got "FFFFFFFFFFFFFFFF" at "1" out of "02316B".
I tried to sent "0620". But no response returned.

Let me confirm serial terminal configuration.

115200 baud, no parity, no flow control, 1 stop bit, ASCII format.

Is this configuration corret?

Oba

Hello Justin,

I tried copy and paste. Then it worked. It returned "k".
