CC13xx with UART

Antonio Racchio

Other Parts Discussed in Thread: CC1310, LAUNCHXL-CC1310, LAUNCHXL-CC1350

Hi, my name is Antonio.

I'm a new of this work. I'm programming and working with the cc13xx device. I was able to install Contiki OS and the 6LBR without any problems. Now I'm going to a new thing: serial communication. My company has given me a switchboard with which I will have to connect it to the cc13xx through the PINs. Through the serial I would like to turn on and off the LEDs, does anyone know how I can move? I've read that I can help Serial-line.c code. Any suggestion will be appreciated

You can study net-UART.c in CC26xx-web-demo.

Hi Yikai, thanks for your help! But I did not understand how to use it, because I am new to serial communication! Could you give me a little example? Thank you for your kindness

Hi Yikai, can you help me?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

There is nothing I can help. What you need is to study the source code.

For the new code of the led on/off on UART, Should I work in the net-uart code?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

Yes, I think you can work in the net-uart code.

I read NET-UART.c, I not think of use the network for on/off led. Can I insert the variable for my work?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

Why not!

What is the command for read on the serial?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

If you study net-uart.c, the UART RX data is kept in data parameter of "PROCESS_THREAD(net_uart_process, ev, data)" and you can use "if(ev == serial_line_event_message) {..." in PROCESS_THREAD(net_uart_process, ev, data) to know there is UART RX data to process.

Hi Yikai.

Yesterday I test it this code and I write input on the serial. Now I want implent a small play with the LED on LAUCHXL CC1310. Have you something example for on/off led?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

There is LED related code in the same link. By the way, do you work the same project with Mario Castaldo?

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

Who is it Mario Castaldo?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

He is asking similar questions on another E2E post so I think you work together. Anyway, it doesn’t matter.

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

I do not know him. I arrived at this point. How see you, If i write 1 i receive 1 but the led don't on or off, the same if I write 0

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

How do you toggle led?

Great! I want to insert in the code cc26xx-web-demo.c, it's possible? But I have the problem, the CoAP page first worked, now no longer. I tried to reinstall it but nothing.

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

1. cc26xx-web-demo.c already uses UART in net-uart.c. If you want to add those UART code into cc26xx-web-demo.c, I think you have to disable/remove net-uart.c/net-uart.h first.
2. Try to define nullRDC and rebuild cc26xx-web-demo.bin to test again.

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

1) Thanks, I tested now
2) The last update of Firefox ver.56 don't function CoAP. You need to upgrade Firefox to version 55

I have disable NET-UART in project-conf,h, but when I generate the file on CC1310 don't work with ON and OFF

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

Make sure you include the code into cc26xx-web-demo.

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

Yes

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

Maybe try to replace the code into net-UART.c and build it to test again.

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

I have to insert the code in the net-uart but not work

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

I replace the code into cc26xx-web-demo and I still can toggle green LED from UART.

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

Ok it works!

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

Why doesn't it work before?

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

My error in the cc26xx-web-demo.h xD

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

Understand and it’s good to know it works now.

Hi Yakai, How are you? I would like to do the same led work, just that i would use two different devices and use the serial (no ethernet). I have two devices connected to the PC. I would like to write "ON" from the first device and the second device turns on the LED

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

I would like a job like this, with two cc13xx: e2e.ti.com/.../607371

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

So, what's your problem?

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

I do not know what code to take for cc13xx

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

If you use contiki, you can refer to sunmaysky.blogspot.co.at/.../using-cc13xxcc26xx-running-contiki-os.html

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

Yes, It works with only 1 cc1310. If I would like to use 2 device. On Device 1 I write ON and on device 2 the led ON

I suppose you have to implement it with UDP server and client to do it by yourself.

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

Via radio (frequency 868 MHz) can not be done? Do you have a guide for this UDP?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

You can refer to sunmaysky.blogspot.co.at/.../how-to-run-contiki-udp-serverudp-client.html

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

Doing this I can switch led from com to one another?

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

I have this problem. The 6lbr found the udp-client but not udp-server. The udp-server resets every 2 seconds

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

No, it is example to exchange data between UDP server and client. You have to do LED toggle by yourself.

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

But should I not read two sensors on the 6lbr? I only read one

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

When you test UDP server and client, 6lbr is not mandatory.

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

So can I even create files without having the active 6lbr? Why does udp server always reset?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

I couldn’t understand your question. Can you elaborate? By the way, do you use LAUNCHXL-CC1310 to test this?

0 Antonio Racchio over 8 years ago in reply to YiKai Chen

Expert 2280 points

I am using LAUCHXL CC1310. To do this communication there is no need for the 6lbr, because the udp-server always resets? How do I see that they are written?

0 YiKai Chen over 8 years ago in reply to Antonio Racchio

Guru 735695 points

How do you build UDP-Server binary?
