I have an application which needs a second UART and a wired Ethernet interface.
The problem with the Ethernet Featherwing as @rickkas7 has pointed out in his response to my previous post, is that the pins used cannot be reconfigured and they use the same pins (D4 and D5) which are the pins for the Xenon’s second serial port.
As a solution, @rickkas7 proposed an excellent solution by using the library he created for the SC16I750
My question is can an Ethernet solution be added to a Xenon (or an Argon/Boron) using the Adafruit Feather which uses the default SPI pins and a configurable CS?
If this approach can be used, which library should one use?
Thank in advance for the community’s input.
