Pins are organised into 7 'banks' (*PA*, *PB*, etc to *PG*) of up to 32 pins, but most banks have fewer pins.
There is a big table in the D1 datasheet that shows all possible functions each pin ccan assume.

The **D1** SOC itself has 88 GPIO pins.

Internally, the **D1** has a number of internal hardware interfaces for different signal types; 6xUART for serial, 2xSPI, 4xI2C(TWI), 3xI2Si/PCM (audio), 8xPWM, and some additional units for USB, HDMI, Audio, and more (see the Data sheet)
The chip has an internal 'pin muxer' to connect pins to signals. Each pin can connect to a (predefined) set of signals, which allows you to map each pin on the GPIO header to multiple possible functions.

You can browse the full range of mappings in the Allwinner D1 datasheet, Table 4-3.

# Precompiled device trees:
Each folder contains a `.dtb` file, which is the compiled device tree itself, plus a `.dts` with the original source and a `.gpio` file showing the GPIO pin mappings.
The tool/data used to assemble the `.gpio` map files identifies which interface a pin is attached to, but not it's specific function for the interface.
* eg it can say 'pinX and pinY are mapped to a UART', but cannot identify which pin is the TX and which is the RX for it; a limitation of the data, my apologies..
* You therefore need to reference the D1 pin mapping table to get the exact functions for pins.
* A copy of this table is available here: [reference/d1-pins.pdf](../reference/d1-pins.pdf)).

To run it you need to be in that directory, then run:
`python3 list-pins.py MangoPi-MQ-Pro`
* This produces the same map I use in the documentation and `.gpio` files in the folders above.
* The data used to assemble the `.gpio` map files identifies which interface a pin is attached to, but not it's specific function for the interface.
* eg it can say 'pinX and pinY are mapped to a UART', but cannot identify which pin is the TX and which is the RX for it; a limitation of the data, my apologies..
* You therefore need to reference the [D1 pin mapping table](../reference/d1-pins.pdf) to get the exact functions for pins when running this for yourself.
* The `.gpio` files uploaded here *have* been manually edited to note full pin function for convenience.
# Install the Device Tree
Installing is, in principle, simple.
