/** Dear pinetab hardware geeks!
*
*
* The current pinetab lora module has a slight bug. The ch341 part only provides ISR assertions on edges.
* This makes sense because USB interrupts happen through fast/repeated special irq urbs that are constantly
* chattering on the USB bus.
*
*
* But this isn't sufficient for level triggered ISR sources like the sx127x radios. The common way that seems to
* be addressed by cs341 users is to **always** connect the INT# (pin 26 on the ch341f) signal to one of the GPIO signals
* on the part. I'd recommend connecting that LORA_DIO0/INT# line to pin 19 (data 4) on the pinetab board. This would
* provide an efficent mechanism so that the (kernel) code in the cs341 driver that I've slightly hacked up to see the
* current state of LORA_DIO0. Without that access, I can't know if the interrupt is still pending - which would create
* race conditions in packet handling.
*
* race conditions in packet handling.
*
* My workaround is to poll the status register internally to the sx127x. Which is expensive because it involves a number of
* i2c transactions and many trips back and forth between kernel and my userspace app. I think shipping the current version
* of the pinetab lora device would be fine because I can poll slowly (because lora is slow). But if you ever have cause to
* rev this board. I highly encourage this small change.
*
*
* Btw - your little "USB lora dongle" is really neat. I encourage you to sell it, because even non pinetab customers could
* use it to easily add lora to rasberry pi, desktop pcs etc...
*
*
* Porduino helper class to do this i2c based polling:
