What does that mean?
Do you get error messages? Be a bit more descriptive of your problem.
Besides the mentions above, I do not see anything glaring obviously wrong with your code. There are a few things I'd do differently, like GPIO pin choices. The pins you used should work fine.
So right now that your code looks good I require more input .
I strongly recommend you use the other SPI buss for the t-couple thingies. I have, in the past, ran into the display units that use extra pins sometimes do not play nice with the SPI buss.
