Playback Funtionality

Add a playback feature, allowing signals that are saved or just sampled to be replayed back on the same or different channels. Similar to Arbitrary Waveform Generator, from a digital (or even better analog) perspective. This likely would require redesign of your Hardware? Logic Pro 2.0?

    Hi Perro, feel free to upvote the related issue, adding output capability, here:

    I would LOVE to have this feature. It would really help with debugging intermittent signal disruption issues. It would be helpful to have the ability to replay a captured signal at original or selectable voltage, on the same or selectable channel(s).

    Yes - another vote for this. Ability to just playback sampled signals. Good for testing a reverse engineered interface against the original to see if it works.

    I would expand this to just be arbitrary waveform generation, with the ability to use a saved/sampled waveform.

    Add a yes vote from me; this would be a huge help for me. I need to play back 3 digital signals with a modest 10 Ms/sec sample rate (even 1 Ms/sec may be sufficient). I have many captures of 3 digital signals I'd like to play back so that I can debug my firmware that is attempting to decode periodic packets that appear in some level of digital noise. It would also be very useful as a means to perform regression testing on newer versions of firmware against a recording with known number of expected decode packets.

    I have need to playback (3) 3.3V digital signals captured at a humble 1 Ms/sec. Simple playback with no options would be sufficient for me. Python would be OK if easier to implement. I'd be willing to pay $500 USD for this.

    Our friend Jonathan just came out with this device that can record and play back SPI, I2C, etc: However if you want arbitrary (not protocol) digital replay then it'll have to wait for the next gen hardware unfortunately. I'm not aware of a another solution, although you might see if Sigrok has something.
