  1. Hello jpeyron, >Also could you attach some screen shots of this issue. The original post contains the screenshot clearly showing the result of reading data by Windows Terminal and AD2 and the difference that bothers me. thanks
  2. Hello, I have a question about UART in AD2. Is it a hardware or software implementation? I was playing with a small ESP2866 board which is controlled through serial interface. I noticed that often AD2 would receive data from the module and display it as binary data. Normally it happens to long strings while short responses / first 1-20 bytes of long responses are displayed correctly. Being intrigued by that I tried to connect the ESP2866 through USB to TTL serial adapter using Windows Terminal, Serial Monitor in Arduino IDE, from my own Python program (based on pySerial) - in all those cases I would correctly receive data of any length. Eventually I just connected the TX line of ESP2866 to AD2 TX while keep it connected and controlled from Windows Terminal via USB to TTL and got the screenshot that fully confirms what I am saying. Could somebody explain to me why AD2 fails to decode proper serial communication ?
  3. Hello attila & jpeyron, Thanks for the provided explanation. best, av_disp
  4. Hello, I have a question regarding the quality of oscillogram displayed by the oscilloscope ( the screenshot is attached). The wave generator generates slow square wave, the channel 1 is connected straight to the wavegen 1 output. But when you examine the signal you see those yellow areas surrounding the leading and trailing edges and that's a bit confusing. What is this and is there anything I can do to get rid of it? Actually, I don't believe that it has anything to do with the signal itself (but I am not an expert), I would think that this is simply how the picture is drawn on the screen. Thanks!
