HI. I have a question about this mod’s compatible hardware. The UI offers a few different display types, but only SPI pins are offered up in the UI. So, no I2C displays seem to be supported, but according to usermod_v2_four_line_display_ALT.h:
//
// Inspired by the usermod_v2_four_line_display
//
// v2 usermod for using 128x32 or 128x64 i2c
// OLED displays to provide a four line display
// for WLED.
So how / where are the pins for SCL and SDA defined?
I did, but found no information pertaining to my question. As a matter of fact, the readme say to look at the original user mod, but that mod was not in the download I got:
I’ve not ever used more than one I2C device at once. If there are more than one, are they connected in parallel, i.e. multiple SCAs connected to pin 21 and multiple SCLs connected to pin22, and the bus address is used to communicate with that node?
Edit 1: I was too excited
The SPI version is more expensive. I got it to test because I wasn’t sure about the I2C connection, but I will order one to test, and if there are no noticeable differences, use them in the future.
