  1. Thanks, increasing the history to unlimited is the thing I need!
  2. Hi everyone, I am new to AnalogDiscovery and new to SPI. So it is a beginner's question, I apologize. I am debugging an SPI connection which works most of the time, but not always. The setup is fairly simple, it is an Arduino communicating with an RFID-RC522 module. I would like to know if the master (Arduino) fails to send or the slave (RC522) fails to respond. I use protocol --> SPI and and click the "Command" checkbox to observe the communication. I did not find a means of triggering the protocol viewer. The data quickly scrolls out of the screen and I am hardly quick enough to click the stop button or make a screenshot. So I thought of writing a script which puts the result in a file which I can examine later. Or, better, the script would write only interesting data to the file. As far as I have seen, there are commands to read from the slave or act as a master, but not read from master and slave. And I need to specify the number of bytes when reading, but I do not know how many bytes will be sent. Thank you.
  3. And where is this thread now? I didn't find it. @Burkhard, could you post the script? Thank you.
