Hi Alexis, I guess I slowly understand that my clocking signal connected to scan_begin_arg has to come from an external DIO input, if scan_bigin_src = TRIG_EXT, and that the insn instruction is still needed to trigger the entire acquisition. Alternatively, would it be possible to use the

Hi Alexis, thanks a lot for the explanations. One item I am confused about is that you write that TRIG_TIMER is not suitable for DIO, but in cmd_write.c in your sample code, it is used for the analog write without problems. Wouldn't one be able to just use the same clock source for DIO as in
