Daniel Krebs	b6dbc7a8a7	comedi: config tuning to reduce latency for demo	2018-06-15 17:43:29 +02:00
Daniel Krebs	fe302f9649	comedi: implement ADC and DAC directions, only DAC tested ... The write / DAC direction has been tested with two output signals, see etc/comedi.conf for reference. For now, the buffer size may not be (considerably) smaller than 32kB, Comedi stops working for unknown reasons. To compensate for the latency (always approx. one buffer size) if only small sample rates are required, configure the path for upsampling (sample-and-hold via rate parameter) at the same rate as the out direction of the comedi node.	2018-06-15 15:47:10 +02:00
