I want to analog signal for vision via BBB. Can we buffer tihs signal for show them as a digital on interface like C# after convert analog signal to digital image.
Is this possible convert analog signal to digital image as a real time with it?
It’s not really clear what you mean by ‘digital image’.
The BBB CPU has an in-build ADC subsystem that can sample analog data on up to 7 channels (input lines) in 12 bit resolution. If you need high sample rates (‘real time’) you should have a look at libpruio (up to 200 kSamples/s is possible).
