But you can actually very carefully prorgram which ones to read into what register, and have you notified once completed. Oh, and to make it even better: The ADC is used by two processors, by the Application Processor (that runs linux) and the Baseband Processor ;) I've now fixed that interrupt problem, but I have some other issues in the state machine that is required for alternating pressure/xy reads. Confident that those things can be fixed, though. -- - Harald Welte <[email protected]> http://gnumonks.org/ ============================================================================ We all know Linux is great...it does infinite loops in 5 seconds. -- Linus
