Well, if manufacturer designed board such as it sends 3.3v to RPi, that is not bad pratice. Without a IT link, safe bet is to tell it might fry RPi... Waveshare did design for 3v3 compatibility.I did indeed mean 5V. The Waveshare display I am using has a voltage regulator and accepts 3.3v/5v as per their documentation. Hooking that up to one of the compatible 5v ouput pins on the pi header it works well, so I would not describe it as lethal. Maybe bad practice?
CLK, MISO and MOSI can be wired together.- I read over that wiki article and a lot of it made sense but I couldn't find anywhere in there how to wire two different SPI devices up to the same Raspberry pi header and, as the title implies, this is really what I am looking for here.
Each device **must** have its own chip select line (and one **must** take care software does not select simultaneously different chips/boards)
