Apologies if this is the wrong place, it’s sort of very specific and very general! :|
So I have a Inky 7 colour Impression and it’s my desk calendar.
I love the simplicity and the fact that it doesn’t radiate light! Perfect for an unobtrusive thing like a calendar.
I want to add another display for a clock and any ‘right-here-right-now’ (hah, I know what song YOU have stuck in your head now) messages like ‘package delivered’ emails or ‘your chair is ACTUALLY on fire right now’ notifications.
I asked the Discord community and a simply marvellous individual suggested it might be tricky as the circular Hyper Pixel I was looking at likely requires too many pins in comparison to the Inky, which although it attached to all pins, actually only required a subset.
That got me thinking about the Adafruit SHARP LCD panel and that’s appealing as it looks like its only I2C or SPI so likely will be fine, but then I actually looked at my Inky and I’m now baffled as to how to get pins off for SPI or I2C.
I see there’s a pin marked block with 3v3, SDA, SCL, #4(?), GND, MOSI, MISO (nom nom), SCK, CE1 (again, ?) and 5v but these look to me to be connectors in some way for the Inky…
…but then I look under the mounted Pi and I see a LOT of board connections, and I light shine highlight the traces and only a couple of the pin marked block pins have top traces, so what is this block for?
…which then leads me to, how on earth do I ‘normally’ connect additional things to Pi pins?
…which is always and consistently predicated by me thinking ‘I’m missing something stupidly obvious, aren’t I…?’
