I finally went back to work to my data acquisition infrastructure. I'm now trying to increase the sampling frequency of my control loop. I do not have any problem up to 10 kHz, but when I increase the sampling frequency above this limits the ADC driver stop working fine. In the kernel log I obtain a huge list of Analogy: analogy_ni_pcmio: ni_mio_common: interrupt: didn't clear interrup? status=0x9030 >>From where can I start to investigate this problem? I encounter this problem only when I use analogy commands with the TRIG_WAKE_EOS flag. If I do not specify this flag all works fine up to 100 kHz. However I need my data in real time, and therefore I need to specify this flag. Cheers, -- Daniele
