The adc source for bbio should be useful. Keep in mind that these sysfs interfaces are incredibly slow compared to memory poking since each operation requires opening, reading/writing and closing the file. For example, with GPIO, you're limited to a few hundred khz (regardless of language since it's just file operations). With mmap and python, you can toggle at > 3Mhz. C a bit faster. Kernel, 12Mhz. There are python and closing libraries that handle all of the memory poking. Also, check out libpruio. It will setup the pin muxing, and provides quick adc and GPIO support. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
