mruby-fm3gpio

FM3 GPIO class

Methods

method	parameter(s)	return
GPIO#mode	Pin No, OUTPUT/INPUT	(nil)
GPIO#write	Pin No, HIGH/LOW	(nil)
GPIO#read	Pin No	HIGH/LOW

Constants

constant
GPIO::OUTPUT	use as digital output
GPIO::INPUT	use as digital input
GPIO::HIGH	output/input HIGH(1)
GPIO::LOW	output/input LOW(0)

Pin No

port No
Pmn	0xmn	m:0-F, n:0-F
ex: P23 -> 0x23

Sample

使い方はおおむねmruby-WiringPiに合わせてあります。

# LED port: P10, STATUS port: P11
GPIO_LED = 0x10  
GPIO_STATUS = 0x11  

a = GPIO.new  
a.mode(GPIO_LED, GPIO::OUTPUT)  
a.mode(GPIO_STATUS, GPIO::INPUT)  
case a.read(GPIO_STATUS)  
  # LED ON  
  when GPIO::LOW  
    a.write(GPIO_LED, GPIO::LOW)  
  # LED OFF  
  when GPIO::HIGH  
    a.write(GPIO_LED, GPIO::HIGH)  
end
