Sorry about lack of description I figured out that I had wired wrong due to a different level shifter model however I could still use help if you wouldn't mind helping a total noob. My mosi isn't pushing 3.3 volts it's very strange my clock is pushing correct voltage so I just don't know what's going on. Would you know where I can change it to the other mosi pin?

Sorry, for the next few Months I have no time whatsoever for this project. I'll leave the issue open, maybe another user can help you.

No worries man I appreciate the response

Have you definitely enabled SPI? https://www.raspberrypi.org/documentation/hardware/raspberrypi/spi/README.md Or perhaps double check your connections or try the other MOSI/SCLK pins? https://pinout.xyz Or even try another Pi?

It worked straight away for me on my Pi Zero.

I think I need a new pi I had it working but one of my solder joints was garbage on my pi and it corrupted my SD card when. I reformatted and reinstalled it stopped. I enabled the alternate spi pins and it still isn't working. Curious thing though when I do a loop back test my misogyny can still read the mosi output.

Are you sure your level shifter is working properly?

WrigglyTentacles commented 7 years ago

I'm fairly certain I was using a voltmeter and my input was still coming out at over 5v
