Making a few I2C connections between modules (new and old) and, upon power-up, the screen is black, can’t enter anything. Have tried a number of slightly different configurations for the I2C connections, always yielding the same results, and since the possible combinations are effectively endless, I thought I’d reach out for a hand. Have moved everything to my bigger case (where only modules on the bus are currently installed) and this eliminated the possibility that it’s a power issue.
Modules on the bus:
No other gear (such as grid, 16n) plugged in at startup. Also attaching photos of the connections in the back in case there are some GLARING ERRORS. I’ve read the I2C guide repeatedly, as well as poking round the thread – but maybe I missed something?
I’ve read star config is bad but that it’s mostly a concern in larger setups, and mine is still, I think, ‘smoll’. This is the same problem I had with just two on the bus, and it was usually a ‘flip wires around till it works’ kinda situation. However, the combinations skyrocket when you jump from 3 modules on the bus to 5 and trying every possible config maths out to, roughly, an eternity.
