Can anyone point me to documentation that identifies the mapping between device names like COM1 and COM2 etc. and the I/O pins of the Netduino Plus 2?
I can see in the schematic that D2/D3 are related to the chip USART2, and D7/D8 are related to the chip USART4, but I would guess there must be some specific documentation somewhere that tells me which pins are defined for COM1 and COM2?
In the Tech Specs, I also see the mapping between internal USARTs but it does not seem to agree with the schematic. The Tech Specs say D2/D3 is UART2 and D7/D8 is UART3 (not UART4). Perhaps I am getting confused looking back and forth. But in some sample code I have found it appears I need to use COM1 type names. I could use the scope and try to write code to wiggle pins for COM1 or COM2 but I hope there is some helpful documentation available for such things.
I have tried to search the forum and used general google searches but have not found this type of documentation so far.
Perhaps there are header files that provide a guide to such things? I am new to the .NET environment so I am sure there are many fundamental pointers I still need to learn about.
