I'm working on a data logger project. I would like to read values from a digital gauge (digimatic protocoll) and temperature values (MAX31855) and save them to a sd card. Now I got my digital gauges and the sd card working. But I've read it could be a problem with SPI (MISO, MOSI, CLK) when I use a sd card board on SPI and also the MAX31855. The solution for this is to use software SPI instead of Hardware SPI for the temp sensor.
My Question is, can I use five MAX31855 with the same pins for: Data Out and CLK and only the CS on different pins, or do I ned for every tempsenor 3 different pins?
