That was my interpretation of the (untranslated) datasheets. I've also come across this Arduino blog:
http://blog.3d-logic.com/2015/01/21/ard ... t-display/
and, being a 'C' programmer, hope to adapt that code to bit-banged code for the Pi to drive the CATALEX TM1637-based displays shown here:

(Currently I'm working on code for the other, 74HC595-based SPI (QIFEI) display also shown in the above page and related code for this "recycled" ex-DTV display and 2 x 74HC595-based interface board**:

I will re-post when I've made progress.

is awaiting an update in the next day or so.
has now been updated.
Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, 2xB2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, and a A+) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm
