Transfer sensor data from arduino trough SPI interface to Spesific loc memory

I have a problem with my final year project. I want to integrate Sensor with RFID tag, so after browsing through the internet I found the Chip/IC that makes it possible. It's Rocky100 IC from Farsens Company. I've got the Rocky100 IC Development Kit so it has a pin to connect with an external device and read the Datasheet. The user data can be stored in this chip starts at 0x30 till 0x6E memory location of the chip.

The IC has SPI Interface so it can be connected with a microcontroller, I decide to use Arduino and DHT22 sensors.

I think the problem is simple I want to store the DHT22 sensor data and send it via Arduino SPI Interface to user data memory location on the IC. I'm new with Arduino and have so-so C programming skills.

I really need your help guys, please be kind,

I attach the Datasheet of Rocky100 IC link below,

From your description and that of the Rocky100 it is not completely clear to me how you intend to use this device.

As I see it from the data sheet, the special feature of the Rocky100 is that it can harvest energy from the reader so it can interrogate low power SPI peripherals and do something with the data.

Are you intending to connect the Rocky100 directly to the DHT22 sensor ?

Maybe draw a diagram of all the components including the Rocky, DH22, Arduino(s), power sources etc. and show their interconnections (Physical and over the wireless link)

In principle, using an Arduino to connect over SPI to devices (both in master and slave mode) is quite simple, if that is what you are intending to do, and this guide is quite comprehensive: http://www.gammon.com.au/spi
