    The driver is to be used with Solomons hardware SSD1333. It is a 176 x 176 RGB driver with the possibility to be set as 528 x 176 Gray Scale (GS) driver. RGB columns become GS controlled. We use 2 of these SSD1333 chips, one on top of the other, to form an image of 528 x 352 pixels, with each SSD1333 device on its own SPI bus. This means that a full 528 x 352 image needs to be split in two 528x176 to be sent to two different SSD1333 chips hanged on two different SPI buses. We want the driver to be able to write an entire image of 528 x 352 pixels on display, as well as, to control individual pixels, rows and columns, with the intention of ease display testing. Check attached display scheme for better understanding. This driver should provide fps configuration and synchronization between...

    I have a small vertical garden supplied with water from a 40 l container (upper left, in video) run through a set of gardena hoses. It's currently turned on and off manually. However, I would like that to programmable for when on vacation. The problem, however is that the gravity-pressure from the container is not large enough to push through most of-the-shelf systems, I think, probably because they are these tight electromagnetic valves. I therefore want to buy a solution that can overcome this. I call it an Arduino-controlled ball-valve because I think that would be a neat solution, but really anything you suggest that convincingly sounds like it would work is something I'm interested.
