Zedboard Sensor project

Good day,

I am currently working on Zedboard for education purposes. I would like 
to implement a project in which I will use a force sensitive resistor 
sensor and then I will have the force value written on OLED which is 
placed on Zedboard. The attachment is a picture from the set up. Sensor 
signal is entered to Zedboard through 12 bit SPI ADC. However, I could 
not find any tutorial explaining usage of sensor with Zedboard. I think 
I should use SPI block but I do not know how to use it and could not 
find any tutorial about that, either.

Can you help me about how can I read this sensor and write its value on 
display?

Thanks.

First: if you have so much questions then the ZYNQ with ist arm cortex 
cores and linux, then this board is too much for you.

There are docs for the SPI Module, just search "xilinx axi spi"
On the digilent website fpr the zedboard there is a "Embedded Linux 
Hands-on Tutorial" which descibes everything from including your cores 
in the fpga up to using them from inside the linux userspace.

Here is a tutorial about SPI in VHDL.
