Using CC13xx/CC26xx running Contiki OS to toggle LED from UART.

The following example shows how to using CC13xx/CC26xx running Contiki OS to toggle LED from UART.

1. Replace the following code into hell-world.c

#include "contiki.h"
#include "dev/cc26xx-uart.h"
#include "dev/serial-line.h"
#include "dev/leds.h"

#include < stdio.h >/* For printf() */
#include  < string.h >

 PROCESS(test_serial, "Serial line test process");
 AUTOSTART_PROCESSES(&test_serial);

 PROCESS_THREAD(test_serial, ev, data)
 {
   PROCESS_BEGIN();
   cc26xx_uart_set_input(serial_line_input_byte);
  
   printf("Hello, world Serial line test\n");

   for(;;) {
     PROCESS_YIELD();
     if(ev == serial_line_event_message) {
       printf("received line: %s\n", (char *)data);
       if(strcmp(data,"ON")==0)
           leds_on(LEDS_GREEN);
       else if(strcmp(data,"OFF")==0)
           leds_off(LEDS_GREEN);
     }
   }
   PROCESS_END();
 }

2. Build hello-world.bin for LAUNCHXL-CC1310 using  "make TARGET=srf06-cc26xx BOARD=launchpad/cc1310 hello-world.bin"

3. Download hello-world.bin to LAUNCHXL-CC1310 using Flash Programmer 2.

4. Start a terminal tool like teraterm to connect to LAUNCHXL-CC1310 application virtual COM port..

5. Enter "ON" and "CTRL+Enter" to send ON command with end character "0x0A" to LAUNCHXL-CC1310 and you will see green led is turned on

6. Enter "OFF" and "CTRL+Enter" to send OFF command with end character "0x0A" to LAUNCHXL-CC1310 and you will see green led is turned on
