“The product still does the job, BUT.... Adafruit have apparently tried to consolidate their software. The new software has the 'I2C plate' code bundled with the GPIO based product. Very confusing. Also it has issues. Scrolling is awful. It scrolls the whole 2 lines at once. And you cannot address lines directly. I looked for the old version of the software. In that, the i2c library has gone, just missing, lost ?.
I found a version of that library pertaining to be for the beagleboneBlack (a fork of Pi version) (Tried it...It WORKS, with a few minor compatibility changes.) I now use the OLD version of Adafruit I2C Plate with the forked I2C. I have written my own code for writing individual lines, will write my own line scroll (a bit harder). I have two simple python files for these drivers, and have uninstalled all the Adafruit bloat.
Note that colours are on or off, not variable as implied in the code.”
“With just 4 wires attached to the header instead of the 26 pin GPIO (5v, gnd, SDA, SCL) - this makes a convenient separate display for my streaming radio project - connecting to those pins through the voice hat that I am using to drive the speaker in its cardboard box. I have the pi (2) in a much modified Smarti-PI (Lego) case (adapted to take the ((Google) voice) hat.)
Using python3 - the install with pip needs to be updated to pip3 - then it works.
Could do with some slightly better documentation - you mostly have to read the code - not too hard, though!
Some of the code is for the fully wired (to GPIO) unit rather than this i2c version, so a little confusing. The (non-plate) examples mangle the voice hat - once I figured out not to use those examples it was good.”
“Hello,
The LCD was easy to assemble, just a little bit of soldering.
The instructions for assembly were easy to find and the code exaples allowed me to quickly put it in production.
It is currently used at home to display the time and date and the minutes until the next bus at the nearest bus stop.”
