<gpio_get/>
Get the value of current GPIO inputs.
Parameters
None
Detailsy
The following table maps the named lines on the Aardvark I2C/SPI and the Promira Serial Platform output cable to bit positions in the value mask that is returned. If the line is logic low the bit will not be active in the bit mask.
A line's bit position in the mask will be 0 if it is configured as an output or if it corresponds to a subsystem that is still active.
All GPIO API functions will index these lines through a single 8-bit masked value. Thus, each bit position in the mask can be referred back its corresponding line through the mapping described below.
| Pin # | Bit Value | Description |
| Pin 1 | 0x01 | I2C SCL line |
| Pin 3 | 0x02 | I2C SDA line |
| Pin 5 | 0x04 | SPI MISO line |
| Pin 7 | 0x08 | SPI SCLK line |
| Pin 8 | 0x10 | SPI MOSI line |
| Pin 9 | 0x20 | SPI SS line |
Please see the Aardvark I2C/SPI Adapter User Manual or the Promira Serial Platform User Manual for more information.
