Soundcard
Revision as of 14:06, 12 July 2022 by Harvie (talk | contribs) (Created page with "Currently there is [https://github.com/sigrokproject/libsigrok/pull/185/ PR pending] to add support for acquisition of analog signals using common soundcard HW. Some cheap USB soundcards can even be modified to bypass DC decoupling and thus enable for DC coupled acquisition. This allows usage of any audio device recognized by OS, therefore it is also possible to use high-end ADC interfaces connected to I2S bus on devices like raspberry pi.")
Currently there is PR pending to add support for acquisition of analog signals using common soundcard HW. Some cheap USB soundcards can even be modified to bypass DC decoupling and thus enable for DC coupled acquisition.
