inputanalog_query(3) Arcan Lua API inputanalog_query(3) NAME inputanalog_query - Query analog devices for filtering details. SYNOPSIS analogtbl_tbl or analogtbl inputanalog_query( devnum, axnum, rescan ) DESCRIPTION This function allows you to query a device for analog device options and current values, either globally (no arguments, table of analogtbl returned) or from a specific device (and, optionally) axis. If rescan is set to != 0, the input subsystem will first scan for new devices. NOTES 1 rescan is a rather costly operation and may possibly lose data for devices that doesn't identify properly. 2 analogtbl members: devid, subid (device and axis indices) up- per_bound, lower_bound (value > upper and < lower will be discarded) deadzone (abs(value) within deadzone will be discarded. ker- nel_size, number of samples in for every sample out. mode(drop), analog processing disabled mode(pass), emit every sample mode(avg), average the kernel_size buffer mode(latest), only emit when buffer full, and keep only most recent value EXAMPLE function inputanalog_query0() local antbl = inputanalog_query(); print(#antbl, "devices found."); for i = 1, #antbl do print("-----0); print(string.format("%d:%d, upper:%d, lower: %d, deadzone: %d, " .. "kernel_size: %d, filter_mode: %s0, antbl[i].devid, antbl[i].subid, antbl[i].upper_bound, antbl[i].lower_bound, antbl[i].deadzone, antbl[i].kernel_size, antbl[i].mode)); print("-----0); end end MISUSE function inputanalog_query0() inputanalog_query("ind"); end SEE ALSO: iodev August 2026 inputanalog_query(3)
