Posted at 2020-07-11 by @allObjects Here the code for the 4 character / single module setup and the 8 character / double module setup. Since there is no chip select, the neg-write signal line is used to write to the desired module. Siemens datasheet and clip of running text on single module attached.
Double module w/ 8 characters using two (2) write lines:

Posted at 2020-07-11 by @allObjects Interesting post-'mortem': The signal sequence and timing of the initially introduced and ultimately working code is different from what the data sheet says: Code:
Datasheet (see attached diagram):
If I do as the data sheet say, I get characters doubled... bleeding into the previous address... I have no definite answer for that except that I do not have exactly the Siemens module which obviously does latch the data only on the rising edge...Attachments: |

I just like displays... here a DL1414T / D SP5-14 .112" Red, 4-Character 16 Segment Plus Decimal Point Alphanumeric Intelligent (Bubble) Display With Memory / Decoder / Driver (and Character Generator for Space thru Underscore, ASCII 32 thru 96). There exist actually versions that have 5 more segments - totally 22 including decimal point and thousand marker, which also support lower case characters (see DL-3422 - 22 Segment Display, on youtube https://www.youtube.com/watch?v=D2cyZoCat_U).
Checkout the shots and clips. Notice the different brightness caused not just by the camera and ambient light setup but also due to powering the display with 3.3 and 5 Volts.
