Pyboard / Micropython interfaces diagram

[Neil Higgins]

The diagram pybv10-pinout.jpg is very handy, but very physical. Can I suggest another version or extension which somehow maps Micropython classes to pins? For example, I understand that there are servo classes that support the direct connection of standard servo devices to groups of three pins (Is it X1, X2, X3 - this was mentioned in a video tutorial). In so far as multiple instances can be configured on different pins, the diagram might need to take a different form, showing what pins can be used, limitations on the number of instances, and clashes that might arise. Easy to say, maybe hard to do, but a quick reference picture like this beats the hell out of trawling documentation.

There is this picture: http://docs.micropython.org/en/latest/quickref.html

which has pins grouped by SPI, I2C, UART, ADC, CAN, DAC, and Timer

For servo, it can use pins X1-X4, and the 3 pin groups are X1, power, ground, etc.

You can also control servos on any pin which has a timer, but not using the Servo API. You'd need to use the Timer PWM code.

The quickref does map most objects to pins: eg SPI(1) on the image corresponds to pyb.SPI(1), and pin X1 corresponds to the object pyb.Pin.board.X1 or pyb.Pin.cpu.A0 equivalently. It's probably a good idea to make this mapping more explicit.

I should also provide a section about the Servo class in the text of the quickref.
