Access GPIOs

Hi,

i got a pretty basic question.

The zynq TRM says you can access the registers with gpio.DIRM_0 and gpio.DATA_0 ...

The example provided by the SDK accesses it with a lot of functions for the XGpio Driver.

What is the better way, and how is it done the first way? I cannot find these registers in my source (system_hw_platform, sandalone_bsp)

You can find all the register addresses in the xparameter.h file. There is the base address located which was assigned to your AXI GPIOs. When you look in the AXI GPIO documentation, you can find all the positions of the registers relative to the base address. Using the XGpioDriver is certainly al lot easier.
