Correct. Neither userspace nor PRU can change a pinmux. > Not correct. In a libpruio configuration all members of system-group 'pruio' can pinmux from user space. That's why libpruio development is as easy as Arduino development, but much more powerful. > If you must have a pin that changes direction and you need to control it > from the PRU, you can use the digital I/O's on the IEP (industrial ethernet > peripheral). I can confirm that this works. > Off-topic. @ P B You asked for GPIO. In order to control the flow rate, you could also control the pumps by PWM signals. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
