This morning, I altered estranged's table (concept from Mark Bramwell
) a bit.
The ordering of the pins is important. People often overlook the fact that the analog pins can also be used as digital pins (since they are not labeled as such on the board). For example, our uMMC
can also use "analog" pins 0 and 1 (digital pins 14 and 15) as a soft serial port.
To help with this, I put the analog pins at the end of the list instead of at the beginning, and also labeled them with their digital pin number equivalent.
Also, because the table will potentially get quite long, using the pin number to indicate usage, instead of just an x, will help with understanding column position - you know those long, wide tables where you have to scroll back a hundred times because you can't remember what each column is for.
What do you think about the positioning of the description/notes field under the pin usage? It's really the only place to put that data, unless you have links to another section - but that gets complicated fast.
