COMEDI_BOARD_INFO(1)

💖 comedi_board_info — the manual page, but make it make sense 💖

okay bestie, this is a User Commands page, and it's literally just here to tell you everything about comedi_board_info. no cap. let's go 🦋

✨ NAME ✨

comedi_board_info — reports useful information about COMEDI devices 👑

🌸 SYNOPSIS 🌸

comedi_board_info [OPTIONS] COMEDI_DEVICE

💅 DESCRIPTION 💅

so basically this program reads info about a comedi device and displays it in a human-readable form. it's giving ✨ legible ✨. periodt.

it also probes the asynchronous acquisition by calling the function probe_cmd_generic_timed, which hands you the tea on two things:

• the maximum sampling rate of the board 🔥
• how the card acquires multiple channels (like, at once, or one by one? iykyk)

and then, the options, which are lowkey the whole point:

• -n NUMBER_OF_CHANNELS — requests the number of channels for the asynchronous acquisition. this might influence the maximum sampling rate AND the mode how the comedi device samples the channels. heads up though: if the number is higher than the available channels, it gets corrected downwards to the number of available channels. the board is not about to let you manifest extra channels, sorry babe 🙈
• -F SAMPLING_RATE — requests a sampling rate for the asynchronous acquisition. by default this is set to comedi's highest sampling rate (1GHz) so that the driver is forced to reduce it and will return the maximum possible sampling rate. iconic behaviour tbh. this option is only provided for driver testing and for drivers which do not return the highest sampling rate.
• -v — verbose output. for the girlies who want the FULL lore 🎀
• -h — shows a brief help screen. your little emergency parachute 🫶
