Getting Started with OSD-Contiki using osd-merkur-256 merkurboard
|
||||
=============================================================
|
||||
This guide's aim is to help you start using Contiki for merkurboards
|
||||
The platform supports different AtMega-RF boards:
|
||||
|
||||
* Based on MCU AtMega256RFR2
|
||||
* Based on MCU AtMega128RFA1
|
||||
|
||||
Boards all looks the same. AtMega256RFR2 boards are labeled with "deRFmega256".
|
||||
The platform and CPU code, are common for both boards, can be found under
|
||||
`$(CONTIKI)/platfrom/osd-merkur-256`,
|
||||
`$(CONTIKI)/platfrom/osd-merkur-128`
|
||||
The port was developed and tested with Merkurboard.
|
||||
This guide assumes that you have basic understanding of how to use the
|
||||
command line and perform basic admin tasks on UNIX family OSs. You should
|
||||
also have understanding about the Contiki OS design as well have C
|
||||
programming skills.
|
||||
|
||||
OSD-Contiki Features
|
||||
--------------------
|
||||
* Contiki Features
|
||||
* Arduino compatible
|
||||
* use Arduino Libs in your Project (see ../examples/osd/arduino-* )
|
||||
* store rf parameter at eeprom
|
||||
* OTA-Features (Update over the Air)
|
||||
|
||||
Board Features
|
||||
----------------
|
||||
* wire Antenna.
|
||||
* Robust radio performance. Up to 300 meter line-of-sight.
|
||||
* Unique EUI64 address via Bootloader
|
||||
* 32kHz RTC xtal
|
||||
* Standard. 6-pin TTL-USB header for FTDI cable for UART.
|
||||
* PCB formfactor for cheap project breadboard
|
||||
* Power/current:
|
||||
* RX ~10mA (Full RPC AtMegaXXRFR2).
|
||||
* Sleep ~45uA @ 16MHz XTAL
|
||||
* Sleep ~15uA @ 8MHz using internal oscillator
|
||||
* Preprogammed arduino bootloader with update over the Air support.
|
||||
* CE certified by test institute.
|
||||
|
||||
UART
|
||||
----
|
||||
The board has one UART via the 6-pin TTL-USB adapter, The recommended
|
||||
baudrate is 38400 bps. This speed gives the lowest error with respect
|
||||
of the used clock frequency used internally. A possible hi-speed is
|
||||
250000 bps wich gives 0% Error with 16MHz clock.
|
||||
|
||||
Port Features
|
||||
--------------
|
||||
The platform has the following key features:
|
||||
* Standard, E64 address from built-in chip.
|
||||
* First hooks for RPC (Reduced Power Consumption) for AtMegaXXXRFR2.
|
||||
|
||||
Toolchain needs
|
||||
---------------
|
||||
The Atmel toolcahin is available in most operating system.
|
||||
Note. We use Debian 9 as reference Linux
|
||||
|
||||
|
||||
###### For Linux
|
||||
|
||||
sudo apt-get install avr-libc binutils-avr gcc-avr gdb-avr simulavr avrdude make git
|
||||
sudo apt-get install python-pip
|
||||
pip install intelhex
|
||||
sudo apt-get install picocom libcoap-1-0-bin
|
||||
|
||||
###### For Windows
|
||||
|
||||
Goes here // todo
|
||||
|
||||
|
||||
get the source code:
|
||||
--------------------
|
||||
|
||||
git clone https://github.com/osdomotics/osd-contiki.git
|
||||
cd osd-contiki
|
||||
git submodule update --init --recursive
|
||||
|
||||
Contiki build TARGET
|
||||
--------------------
|
||||
|
||||
For AtMega128RFR2 boards:
|
||||
|
||||
make TARGET=osd-merkur-256
|
||||
|
||||
For AtMega128RFA1 boards:
|
||||
|
||||
make TARGET=osd-merkur-128
|
||||
|
||||
Flashing
|
||||
--------
|
||||
Programming using avrdude using serial bootloader. (TTL-USB cable)
|
||||
|
||||
Flashing commnad line example 256k MCU:
|
||||
|
||||
make TARGET=osd-merkur-256 flash
|
||||
|
||||
Flashing commnad line example 128k MCU:
|
||||
|
||||
make TARGET=osd-merkur-128 flash
|
||||
|
||||

||||
This port adds newer version of `avr-gcc` compiler (4.9.2), to support
|
||||
testing of newer Atmel MCU as Atmega256RFR2.
