I wrote a code as following
pt = 0xFF;
simpleserial_put(‘r’, 8, pt);
then I capture the trace with 22400 samples setting. The trace I got is as below:
Interesting, once the
trigger_high() starts, it captures everything but
trigger_low() does not stop the capturing immediately. It seems like the
trigger_low() stop the scope to be trigger continuously. Also, the time of scope to restart capturing is fixed.
My questions are:
- What is the time that the chipwhisperer will restart the capture ? I’m using Chipwhisperer Lite.
- Once I start the
trigger_high(), it starts to record the trace from the first signal to the signal 22400 and these are the samples I get when I call
