+Maxim MAX3420E on a DATQ1THD6B0 touch screen module
+-------------------------------------------------------------------------------
+
+This directory contains captures of the SPI/USB communication of a
+DATQ1THD6B0 touch screen module (used for TFT monitors).

+The samplerate here is only 32MHz, USB may not be entirely decodable. This
+is a capture which is only meant to show the timing of when the two other
+PCBs are initialized relative to the main PCB.
