Import FutureBoard Library

Import the Library to make use of its functions.

from future import *

05: GPIO

1. Initiate Pin Mode

MeowPin(pin,mode)

Initiates the GPIO with a mode, use P1~P16 for parameter pin.
Possible values for parameter mode:

Digital Input: ‘IN’
Digital Output: ‘OUT’
Analog Input: ‘ANALOG’
Analog Output: ‘PWM’

2. Read a Digital Value

getDigital()

Sample Program

from future import *
# Digital Read Pins=['P0','P1','P2','P3','P8','P9','P12','P13','P14','P15','P16']
p0 = MeowPin('P0','IN')
print(p0.getDigital())

3. Write a Digital Value

setDigital(val)

Sample Program

from future import *
import time
# Digital Write Pins=['P0','P1','P2','P6','P7','P8','P10','P13','P3','P9','P14','P15','P16']
p0 = MeowPin('P0','OUT')
while 1:
p0.setDigital(1)
time.sleep(1)
p0.setDigital(0)
time.sleep(1)

4. Read an Analog Value

getAnalog(width)

FutureBoard has a 12-bit ADC, use 10 for 10-bit values and 12 for 12-bit values, default is 12.

Sample Program

from future import *
# Analog Read Pins=['P0','P1','P4','P12', 'P3', 'P14', 'P15', 'P16']

p0 = MeowPin('P0','ANALOG')
print(p0.getAnalog())
print(p0.getAnalog(width=10))

5. Write an Analog Value

setAnalog(val)

Sample Program

from future import *
import time
# Analog Write Pins=['P0','P1','P2','P3','P8','P13','P14','P15','P16']

p0 = MeowPin('P0','PWM')
while 1:
for i in range(1023):
p0.setAnalog(i)
time.sleep_ms(1)
for i in range(1023,0,-1):
p0.setAnalog(i)
time.sleep_ms(1)
