2022-07-07 First signals on the logic analyzer circuit
The logic analyzer circuit I ordered came in today with the test leads. Both the circuit and the test leads have pins so I need something to connect those two. So the crate with PC cables was ransacked and a floppy drive cable is now connecting the logic analyzer and the test leads. The logic analyzer shows up in linux as usb device:Bus 002 Device 008: ID 1d50:608c OpenMoko, Inc. Fx2lafwFinding software was quite easy: pulseview indeed works out of the box, complete with support for this logic analyzer. I had a look around for something to analyze and finally settled on the ESP32 based NTP clock because that's still on a breadboard and signals are available. I can see the bits flowing between the ESP32 microcontroller and the display module. I'm still seeing some bits come in on unconnected testleads so I'm not sure I am doing everything right. But it's a start!
