I didn't write this code (just made some modifications) but it was using a depreciated library so I'm trying to update to the official circuit python libraries and update everything for python3.
This is for a kiln controller that I've been using successfully for a year. It was using some deprecated libraries however, and recent updates broke things. It seems redundant import both RPi.GPIO and digitalio. Since the max31856 requires digitalio, I thought I'd convert the code to use that instead of RPi.GPIO. However, the code just doesn't seem as elegant. I'm wondering if I'm missing something or if I should just keep using Rpi.GPIO?
The HEAT = (23,24) is the the output pins to trigger the relays for the elements. This should be expandable because some kilns use more than 2 elements.
This is the original code
GPIO.setmode(GPIO.BCM) HEAT = (23, 24) for element in HEAT: GPIO.setup(element, GPIO.OUT) GPIO.output(element, GPIO.LOW)
And to turn the elements on and off
for element in HEAT: GPIO.output(element, False)
for element in HEAT: GPIO.output(element, True)
The code I'm comming up with is something like this
HEAT = (board.D23,board.D24) for element in HEAT: element = digitalio.DigitalInOut(element) element.direction = digitalio.Direction.OUTPUT element.value = False
I haven't actually tested this to make sure it's triggering both elements but it doesn't generate any errors when I run it.
Is there a better way to do this? I've tried running digitalio.DigitalInOut(element) with various combinations to avoid the board.D23 in the list but circuit python didn't like those.
