Which Aardvark I2C/SPI Host Adapter Pins Can Be Made Available for GPIO Signals and How Are They Controlled?

▤ Summary

I am starting to use the Aardvark I2C/SPI Host Adapter and I have some questions about the GPIO pins, including how to program them with your software. • Can you provide guidelines for configuring Aardvark adapters MISO pin as an output and setting the logic level? The Aardvark I2C/SPI Host Adapter is compatible with both 3.3V and 5V signal levels out of the box. For example, enabling the Aardvark adapter in I2C mode via aa_configure(handle, AA_CONFIG_GPIO_I2C) allows SPI pins 5, 7, 8 and 9 to be controlled with API calls.
