After reading the documentation its not entirely clear what I can get out of the pattern generator. I'd like to send custom messages via I2S and other protocols with the click of a button. For example, enter the data I want to send, and the device sends the specified data via the specified protocol automatically. Is this possible with the pattern generator on the Digital discovery device or any other devices? Also I see the analog discovery 3 does not list I2S as a supported bus protocol. This seems odd as it is the more premium product than the digital discovery. Is this correct?
