I'm trying to hack my wireless thermostat to control my heating. I disassembled my unit and found the communication chip ( CC110L - SPI 433MHz). I searched for the datasheet and tried to determine which pin is which. I think I found the right pins and connected it to my digital analyzer, but my readings are strange. My clock signal does not look like a clock signal, and the CSn signal looks more like a clock signal but it does not match the datasheet.
Is it really a clock signal? Because my values do not look right. See attachment please.
