Arduino shell example
This example start a shell on merkurboard serial0 line. You can change the network parameters and store it in eeprom.
make clean TARGET=osd-merkur-256 flash
start a terminal programm
picocom -c -b 38400 --omap crcrlf /dev/ttyUSB0
? [ENTER]
Available commands: ?: shows this help ccathresholds <threshold: change cca thresholds -91 to -61 dBm (default -77) exit: exit shell help: shows this help kill : stop a specific command killall: stop all running commands macconf : change mac layer 0 -> do nothing; 1 -> Radio allways on null: discard input panid <0xabcd>: change panid (default 0xabcd) quit: exit shell reboot: reboot the system rfchannel : change radio channel (11 - 26) saverfparam <> save radio parameters txpower, channel, panid to eeprom settingsmanager txpower : change transmission power 0 (3dbm, default) to 15 (-17.2dbm)
example merkurboard set rf-parameter:
panid 0xabcd rfchannel 11 saverfparam
example old merkurboard (atmega128rfa1) set rf-parameter:
macconf 1 *) switch power off/on panid 0xabcd rfchannel 11 saverfparam macconf 0 *) switch power off/on
quit picocom, you need to press Ctrl-a , then Ctrl-q
Read eeprom to disk: avrdude -p m256rfr2 -c stk500v2 -P /dev/ttyUSB0 -b 57600 -U eeprom:r:eeprom_img.hex:i Write eeprom to Merkurboard: avrdude -p m256rfr2 -c stk500v2 -P /dev/ttyUSB0 -b 57600 -U eeprom:w:eeprom_img.hex:i
todo:
atmega128rfa1 reboot dont work correct @ fixme
if rfsleep mode, it is not possible to set panid @ fixme (workaround: set macconf 1, power off, power on, panid 0xabcd, saverfparam, set macconf 0, power off, power on)
This example shows that it is now possible to re-use arduino sketches in
Contiki. This example documents the necessary magic. Arduino specifies
two routines, setup and loop. Before setup is called, the
framework initializes hardware. In original Arduino, all this is done in
a main function (in C). For contiki we define a process that does the
same.
