+Logic analyzer setup
+--------------------
+
+The logic analyzer used was a Saleae Logic (at 6-24MHz):
+
+  Probe       Pin
+  ---------------
+  0           START
+  1           STOP
+  5           DATA
+  7           CLOCK
+
+The sigrok command line used was:
+
+  sigrok-cli -d fx2lafw -c samplerate=24MHz -o <filename> --time 1s
+
+Time, samplerate and <filename> parameters vary depending on the file.
