Is there an example somewhere on how to read and set the GPIO of this chip over USB? 

Kind regards

Hi Dieter,

The KBA mentioned above is referring to the same part number which you are using. The default drive mode of the GPIOs is Tristate. If you have not configured your GPIOs through the Configuration Utility, the GPIOs will be in Tristate. But if GPIOs are configured as RXLed, TXLed, sleep and power, then the default state will be active low.

Hi,

Thanks for the link. In that link it's stated that all the GPIO's are set to Tristate. But in the datasheet the default of only 3 GPIO's is set to tristate, the other  three are RXLed, TXLed, sleep and power. Or is the article regarding another  chip?

Kind regards,

Dieter
