Hi,  
can anyone give a sample of how to configure the GPIO pins 1 and 2 as output mode and GPIO pin 33 as input using the adl commands. And, more importantly how to use the adl\_iowrite() and adl\_ioread()? im confused about the parameters used in these functions. Sample code is a welcome.  
Expecting a reply at the earliest.

Regards,
