Hello, I'm working with the Analog Discovery 2 and have some questions regarding the behavior of its digital I/O pins. I've read through the specifications, but some details about the default states and voltage levels are still unclear to me, both from an SDK perspective and while using WaveForms. Here are my specific questions: What is the default state of the digital pins when they are first enabled? Are they set to a low state, high state, or are they in high-impedance mode? What happens to the pins when they are disabled? Do they default to a specific voltage, or do they go to high-impedance mode? I'm trying to understand the logic levels for proper interfacing and to ensure I'm not causing any unintended shorts or placing incorrect loads on the pins. Any insights, especially regarding the default enabled and disabled states, would be greatly appreciated. Thank you in advance for your assistance!

Hello, I am developing a program using the Waveforms SDK in Python but I am encountering an issue with the single acquisition mode. The problem arises when choosing the buffer, as I need to add a gap, but the pulse width is variable, so I cannot select a gap that is consistently appropriate. My idea is to send multiple pulses, save the data, perform calculations, and then send another pulse. However, if the gap is too small, the signal gets cut off as shown below: Where the signal I intended to send was: If the buffer gap is too large: There is too much space. As I need to send variable pulses, this can be problematic. Is there a way to synchronize the number of points sent with the number received, so as not to lengthen the signal?

Thank you, the issue has been resolved!!

I am writing a custom application in Python for an experiment that involves pulses of increasing amplitude. I am using a .py file to control the device and run the experiment. In the attached images, you can see the desired waveform. However, when I first connect the device, the output is incorrect. But, when I run the experiment for the second time, the output is as expected. I am using the Analog Discovery 2 as the device for this experiment. I would greatly appreciate any suggestions or solutions to this issue.
