AWR1642: Missing Characters from mmWave_Demo_Visualizer

He wei

Part Number: AWR1642

Dear Officer,

We are using SDK2.1 running on AWR1642, and using mmWave_Demo_Visualizer for our testing. When we try to use " LOAD CONFIG FROM PC AND SEND" option under plot, ver often we got missing chraters in the control port hence the device can not be start correctly. e.g.in the configuration file:

"lowPower 0 1"

But our device only got "Power 0 1" hence it will be treated as wrong command.

We did modify some algorithm but we don't touch on the cli.c tasks poart. Any suggestions why we can't get miss characters when receiving from control port from mmWave_Demo_Visualizer? It is the loading too fast from mmWave_Demo_Visualizer?

Tks and best regards

Hi He Wei,
Can you recheck the changes you did?
Try the same experiment with a serial terminal tool (e.g. TeraTerm) to send CLI command.

Hi,

This may be related to the PC
Can you please try to use a terminal emulator to send the commands?

thank you

Dear Jitendra,

Yes. I can send the cmds correctly with other serial terminal tool. e.g using our own Matlab GUI to send over serial port, this is working fine. In the Demo visualizer case, seems some characters being chopped off before putting on the serial port.. Is possible we can check and modify on this portion of Demo visualizer code? Or Can we send our configuration via other serial ports but still using Demo Visualizer to display the output from AWR1642?

Note:

What we change is that: we change some algorithm in DSP side, and we add some new command string, command in MCU Cli.c but we don't change its structure at all..

Tks and best regards

Hi He Wei,
This is very strange issue we hear where Visualizer only is chunking off prefix character of the commands not by the terminal tool.

You can import mmWave Demo Visualizer to your workspace and do any required code change (find out what is causing this issue here)
Please refer this thread talking about importing Visualizer to your devi.ti.com/gc GUI code composer login.
