Accessing IO on external circuitry conected to the FMC LPC Connector

Jump to solution

Hey

 

I have an SP601 Board . I bought a FMC XM105 Debug Card to get access to the FMC LPC connector pins and connected my external circuitry to the pins on the debug card. Now i want to access the IO on this external circuitry using the MicroBlaze. 

 

I know how to access the standard io's used in the sp601 board such as the Dip Switches , Led's and Pushbutton switches using the GPIO IP (by calling the low level functions in xgpio_l.h and reading from the appropriate address mentioned in xparameters.h) on the MicroBlaze. But how do i access the IO's on my external circuitry using the MicroBlaze. 

 

And suggestions will be greatly helpful :)

 

Thanks a lot in advance

You'll be glad to find out that it works the same way, just read from the FMC LPC pins instead of the LED/switch pins.  You'll have to double-check the IOSTANDARD in the UCF as well.
