Here’s my problem. I have an SCP1000 hooked up to my Arduino Pro Mini, but it doesn’t work. I’m getting SS and SCK signals at 3.3V just fine, but MOSI pegs at 1V and so the sensor doesn’t cooperate. When I remove the sensor I do get a 3.3V signal on the MOSI line, so I’m assuming my Arduino is not the problem.
Any suggestions? I have the Arduino and SCP on my breadboard with jumper wires between them, and nothing else. The Arduino and sensor are being powered by the same 3.3V regulated supply. Beyond that I can’t think what else to tell you.
