Linux/LAUNCHXL-CC1312R1: How to use hard serial port to connect raspberry pi gateway with co-processor?

Thanks Chen,

Yes I have flashed coprocessor on CC1312R1 LAUNCHXL.

"I suppose you should use ttyACM0 instead of ttyS0 in collector.cfg"

with ttyACM0 it is working fine but that is not what I want , I am connecting raspberry pi's UART Tx and UART Rx with the CC1312R1's Tx and Rx. and that is why I have selected ttyS0 in collector.cfg as this comment suggests.

Thanks,

Hello Chen,

As you suggested I rechecked the connection and it seems ok to me. I've connected DIO2(RXD) of the CC1312R1 LAUNCHXL with raspberry pi zero's Pin 8(UART TXD) and DIO3(TXD) of the CC1312R1 LAUNCHXL with Rpi's Pin 10(UART RXD). Is it right?

I am getting /dev/ttyS0 as well.

now when I run "run_collector.sh" under "ti154stack_linux_2_07_00_16/example/collector/run_collector.sh" it shows me " Cannot get VERSION info from CoProcessor ".

Can you please help me with this.

Thank You,

Mitul Parmar

Hello Chen

Thanks for the suggestions.

"By the way, you might need to enable UART manually on Raspberry Pi which you can refer to www.circuits.dk/.../"

I checked the link you have provided and according to that my UART is already enabled.

Here is the picture of my connections.

Thank You,

Is the PI positive or negative logic? The launch pad is positive logic, I believe. You might need a scope.

Hello Keith,

Thanks for your response.

"Is the PI positive or negative logic?"

I guess Pi is positive logic, can you elaborate what difference does it make? I don't know much about positive or negative logic.

Thank you,
