Voltage on pin in INPUT mode?
I'm having a problem reading the state on PA19, as it is setting itself to HIGH in INPUT mode?
I have an LED connected between PA19 (via 1k resistor) and GND, then I run the simple script below.
Expected result:
LED remains turned off and "0" is printed
Actual result:
LED turns on and "1" is printed
What am i doing wrong?
#!/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))
