Hi, sorry me again. š š š
I did do a quick search, but couldnāt find anything recent or relevantā¦
Iāve been trying to use the 1.54 LCD (st7789) breakout, with an explorer hat pro. And a SPI breakout garden extender. Sounds simple enough? Right? Well, no, not really. š
I can find 3-5V, GND, CS, SCK, MOSI, without issue on the explorer hat pro. And connect them up with my piratically approved jumper jerky just fine.
I believe that the āDCā as labelled on the LCD BO is the MISO. But then I am left with the mysteries of the āBLā connection.
If I drop the LCD into a SPI slot on one of my breakout gardens, everything works just fine. And there was much rejoicing.
I have one of the SPI OLEDās which works okay on the explorer hat pro. Using āDCā as the MISO. But the 1.54 LCD, doesnāt function, with the same connections. Guessing that this enigmatic āBLā is possibly for colour information?
Looking at this image from the website, thereās a different label for the āBLā which is labelled GPIO.
So my support request is: How can I connect the LCD breakout to by explorer hat pro, so that when I use the command python3 image.py cat.jpg square
the little kitty appears on my display?
Iāve looked up various things including the Pi Foundation pages and pinout.xyz too no avail. Hence posting here.
Thanks for any guidance, mucho appreciated. Arrr, Yarr, and so on. š
