Is there any way for this library to use RPi.GPIO instead of digitalio? #2

Its just so limiting, and inefficient to have to constantly poll the device, since digitalio doesn't support interrupts, whereas RPi.GPIO does support interrupts.

Hi, thanks for your comment. It is inefficient but the driver is written to run under CircuitPython. CircuitPython does not support interrupts. I have the same issue with packet radio drivers. If you are only going to use it with a Raspberry Pi then feel free to fork the code and and interrupt support.

Unfortunately, my coding skills aren't there yet.... But, I think I managed to get it working to capture the interrupt with RPi.GPIO.... seems I had to use the dtoverlay in raspberry pi os so that spidev wouldn't have control of pins 7&8 even though those are the spi pins I'm using.... Since the hardware is no longer latching into them, I can use this library, and Rpi.GPIO to handle the interrupt events on the same pins.... Weird, but it works.
