WiringPi - ovládání GPIO

git clone https://github.com/zhaolei/WiringOP.git -b h3
cd WiringOP
chmod +x ./build
sudo ./build

po instalaci precteme a zobrazime gpio piny

gpio readall

inicializace na zapnuti pinu 23 pro vystup

gpio mode 23 out

zapnuti / vypnuti pinu 23

gpio write 23 0 && gpio write 23 1

osvedcene "standartni nastaveni"

gpio readall

vyhodi tabulku s cislovanim pinu
tabulka nize je jako priklad pro zapojeni 8-port rele

na rele	na opi	barva vodice (kvuli homogenite)
GND	0v	cerny
IN1	wPI 11	bily
IN2	wPI 24	sedy
IN3	wPI 23	ruzovy
IN4	wPI 22	modry
IN5	wPI 21	zeleny
IN6	wPI 1	zluty
IN7	wPI 4	oranzovy
IN8	wPI 5	hnedy
VCC	5v	cerveny

ostatni zapojeni

pripojena periferie	jaky wPI pin pouzit	barva vodice (kvuli homogenite)
data pro 433Mhz transmitter	wPI 0	-
1wire, napriklad na dallas senzor teploty	wPI 25	-

8-port moduly z ciny je lepsi inicializovat po startu, oproti logice rpi maji otoceny statusy, co je low a co high, proto skript nize spoustim po startu. da mmi to i vizualni kontrolu, ze vsechny svetla nabehnou.

relaystart.sh

Pokud nam vse funguje pres commandlajnu, muzeme pokracovat:

MQTT - mosquitto

instalace

Importujeme repo eclipse:

wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
apt-key add mosquitto-repo.gpg.key

Pridame pro apt, podle verze armbianu:

cd /etc/apt/sources.list.d/

wget http://repo.mosquitto.org/debian/mosquitto-wheezy.list
wget http://repo.mosquitto.org/debian/mosquitto-jessie.list
wget http://repo.mosquitto.org/debian/mosquitto-sarge.list

apt-get update
apt-cache search mosquitto
apt-get install mosquitto

testování

subscribe na vsechny topicy (vetsinou jen pro ucely testu)

mosquitto_sub -v -h broker_ip -p 1883 -t '#'

a z jine masiny, kde mame nainstalovano pustime

mosquitto_pub -t 'test/topic' -m 'hellopico'

mosquitto >> command - mqtt-launcher

kdyz nam to funguje, spojime obe casti v celek, za pouziti mqtt-launcher potrebujeme pip

apt-get install python-pip
pip install paho-mqtt

launcher.conf.example prejmenujeme na launcher.conf:

logfile = 'logfile'
mqtt_broker = 'ip-brokera'      # default: 'localhost'
mqtt_port = 1883                # default: 1883
mqtt_clientid = 'mqtt-launcher-1'
mqtt_username = 
mqtt_password = 
topiclist = {
   # topic                     payload value       program & arguments
   "sys/file"          :   {
                               'create'        :   [ '/usr/bin/touch', '/tmp/file.one' ],
                               'false'         :   [ '/bin/rm', '-f', '/tmp/file.one'    ],
                               'info'          :   [ '/bin/ls', '-l', '/tmp/file.one' ],
                           },
   "prog/pwd"          :   {
                               None            :   [ 'pwd' ],
                           },
   "dev/1"             :   {
                               None            :   [ 'ls', '-l', '/' ],
                           },
   "dev/2"             :   {
                               None            :   [ "/bin/echo", "111", "*", "@!@", "222", "@!@", "333" ],
                           },
}

editujeme mqtt-launcher.py, protoze musime pridat „self“, aby vysledny radek vypadal

def on_connect(self, mosq, userdata, result_code):
