IWR6843ISK: Hardware Flow Control (CTS & RTS)

Z.Magday

Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVEICBOOST,

I'm using a Raspberry Pi USB port to receive data from IWR6843ISK (without MMWAVEICBOOST).

I used mmWave SDK Out of Box Demo - 68xx Hard-Coded Config Version.

My problem is that I'm missing some data when reading from the serial port.

I suspect it is due to buffer overflow at high speed.

I think using Hardware Flow Control (CTS & RTS) might solve this.

Does IWR6843ISK support Hardware Flow Control (CTS & RTS)?

If yes, how can I implement this?

If not, how to avoid missing data during reading from serial port?

And also, I would like to ask if the baud rate of the Data port can be changed. Right now the setting is baud rate = 921,600.

Hello,

Please refer to the following thread about Hard Coded Config Implementation:

This should make sure that you are modifying the OOB properly.

I am not yet modifying the OOB. My problem is in receiving the data being sent by the sensor through USB.

I don't have any problem when receiving the data using my PC with TeraTerm.

I encountered the problem when using Raspberry Pi.

So, going back to my questions:

Does IWR6843ISK support Hardware Flow Control (CTS & RTS)? If yes, how can I implement this?

Can I change the baud rate of the Data port can be changed. Right now the setting is baud rate = 921,600.
