Hey all, having issues getting the logic analyzer to work. I'm trying to observe a 3.3V I2C bus, but as far as I can tell the logic analyzer/digital input never trigger. In fact, it appears that the digital input always reads LOW, which is the opposite of what I would expect for I2C. When I probe the digital input, I can see that there is in fact a clock signal.
Any hints for what I am doing wrong? I've tried many trigger configurations, and none of them have worked. I'm not even sure it is a trigger issue, because again, it looks like the clock is being read as LOW when I'd expect it to be HIGH by default.
