When I try to read the input on PA19 immediately goes to "1" even though there is no voltage being sent to the pin.
Example:
#!/usr/local/bin/python
from pyA20.gpio import gpio
from pyA20.gpio import port
pin_to_circuit = port.PA19
gpio.init()
gpio.setcfg(pin_to_circuit, gpio.OUTPUT)
gpio.output(pin_to_circuit, 0)
gpio.setcfg(pin_to_circuit, gpio.INPUT)
print(gpio.input(pin_to_circuit))
I don't understand why this would put "1" with nothing even connected to the PA19 pin?
Are there some settings I need to change to get PA19 working as a normal GPIO pin?
