The modifications you made to the code to support two channels are just wrong, you need to set/clear both output data bits before setting the clock pin high. Also, you'll use far fewer cycles if you can manage to shift out bytes or words instead of single bits, but that will depend on how you have the PRU I/O pinned out and if you can tolerate the extra overhead in the ARM to PRU communications. -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
