I can do simple, one-byte transactions with SPI, using RasPi connected to an RFM69 radio module. I can read and write any register with ease. However, I am now trying to connect the RasPi to a MAX6662 temperature sensor that has 16-bit registers and I don't know how to formulate the grammar and syntax in Python in order to read more than one byte. When I purchased the MAX6662, I failed to notice that it is a 3-wire device, which adds a layer of complication.
