Hello,
I have a Siglent SDS 1202X-E. The UART Decode function has stopped working. I recall it had been working in the past, albeit not very well, but it was usable. Now I can no longer successfully decode very basic UART data. I have updated the firmware to the latest version (1.3.27) and reset all settings, and tried every conceivable troubleshooting step. The Oscope functionality is still fine, and the signal is displayed and triggered and all decode setting are correct as far as I’m aware.
I have (2) Arduino sketches. The first repeatedly sends the character "A" to the serial port. The siglent successfully decodes this. The second Arduino sketch sends the character string "AA". The Siglent fails to decode this. It displays a red error for the first character, and then a single apostrophe for the second character. I have attached the sketches and images for your reference. Edit: this forum won’t let me attach the INO files
As a side note, can anyone recommend a decent, and good value for the money logic analyzer capable of UART decode?
Sincerely,
Marcus
