GPIO Configure Command

<gpio_config direction="direction" 
             pullups="pullups"/>

Configure the GPIO interface.

Parameters

direction

each bit corresponds to the physical line as defined below. If a line's bit is 0, the line is configured as an input. Otherwise it will be an output.

pullups

each bit corresponds to the physical line as defined below. If a line's bit is 1, the line's pullup is active whenever the line is configured as an input. Otherwise the pullup will be deactivated. The Promira Serial Platform doesn't

Details

The following table maps the named lines on the Aardvark I2C/SPI and the Promira Serial Platform output cable to bit positions in the direction and pullups masks. 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
