Task 1: Starting the RIOT

Task 1.1: Run your first application as Linux process

1. Compile and run on native platform:

   make all term

2. Run help to see a list of all available commands

   > help
   help
   Command              Description
   ---------------------------------------
   reboot               Reboot the node
   version              Prints current RIOT_VERSION
   pm                   interact with layered PM subsystem
   ps                   Prints information about running threads.
   

3. Look at the output of ps

   > ps
   ps
           pid | name                 | state    Q | pri | stack  ( used) ( free) | base addr  | current
             - | isr_stack            | -        - |   - |   8192 (   -1) ( 8193) | 0x565b8380 | 0x565b8380
             1 | idle                 | pending  Q |  15 |   8192 (  436) ( 7756) | 0x565b60a0 | 0x565b7f00
             2 | main                 | running  Q |   7 |  12288 ( 3196) ( 9092) | 0x565b30a0 | 0x565b5f00
               | SUM                  |            |     |  28672 ( 3632) (25040)
   

4. Add a print statement to the main() function to output the name of the board.

   printf("This application runs on %s\n", RIOT_BOARD);
   

   Recompile and run again:

   make all term

Task 1.2: Run your first application on real hardware

1. Get to know your hardware

   Atmel SAM R21 Xplained Pro

   

   MCU	ATSAMR21G18A
   Family	ARM Cortex-M0+
   Vendor	Atmel
   RAM/ROM	32Kb / 256Kb
   Frequency	up to 48MHz
   Timers	6 (1x 16-bit, 2x 24-bit, 3x 32-bit)
   ADCs	1x 12-bit (8 channels)
   UARTs / SPIs / I2Cs	max 5 (shared)
   Vcc	1.8V - 3.6V
   Radio	IEEE802.15.4 @ 2,4GHz
   Sensors	none

   Phytec phyNODE KW22

   

   MCU	MKW22D512
   Family	ARM Cortex-M4
   Vendor	Kinetis
   RAM/ROM	65Kb / 512Kb
   Frequency	up to 50MHz
   Timers	up to 12 (16-bit, 24-bit, 32-bit)
   ADCs	1x 16-bit (8 channels)
   UARTs / SPIs / I2Cs	3 / 1 / 2
   Vcc	1.8V - 3.6V
   Radio	IEEE802.15.4 @ 2,4GHZ
   Sensors	diverse

2. To compile an application for a specific board, we can make use of the BOARD environment variable.

   In case you are running on an Atmel board, type:

   BOARD=samr21-xpro make all flash term

   For the (yellow) phyNODE use;

   BOARD=pba-d-01-kw2x make all flash term

   This command will compile the application, burn the image onto the board and open a connection to the RIOT shell.

3. Verify the output of RIOT_BOARD matches your hardware.
