[ROM patterns without assigned IO]

Can ROM patterns be created internally (without the need for an allocated I/O pin)?

e.g. If I want to cycle through a pattern of bits (e.g. 8-bit value) to generate a PWM signal for sinusoid (or mixed sinusoids of different frequencies).  I just want 1 bit output.

Maybe I'm thinking about it wrongly, and just need a 1 bit pattern (pre-computed).

Similarly a state-machine, running through say 16 states, with 2 outputs.  Does it need 4 real I/Os allocated for the states or can they be internal?

[4 Channel Waveform Generator & 4 Channel Scope]

Hi,

I have an Analog Discovery 2, which I love and does most of what I want, however I'm looking for a cost effective 4 Channel Waveform Generator, 4 Channel Scope and Digital IO (the AD2 has only 4 channel waveform generator)

Something like the Analog Discovery Pro 3000 with 4 channel waveform would be perfect.

Does such a product exist?

Can 2 x AD-Pro devices be ganged together and synchronised to so that they are phase aligned and effectively work as a single unit (preferably with a single Ethernet or USB connection)?

Similarly, can and AD-Pro and AD2 be ganged together, or even 2 x AD2 devices?

Any suggestions welcome.

Thanks, Brendan.
