Method 1:
Use WinSCP to upload the downloaded library file to Raspberry Pi4: Link

Tip

The library files are downloaded in the “Previous_tutorial” section!

Method 2:
Open the Raspberry pi4 or Git terminal and run the following command to download it from github.

 git clone https://github.com/mosiwi/Mosiwi-4x4x4cube    

(Terminal of Raspberry pi4)

Add execute permissions for the files:

 cd ~/Mosiwi-4x4x4cube/Pi4/c/examples/3wire/
 sudo chmod 777 cube Makefile

 cd ~/Mosiwi-4x4x4cube/Pi4/c/examples/spi/
 sudo chmod 777 cube Makefile

Run code

---

3wire example.

cd ~/Mosiwi_4x4x4cube\Pi4\c\examples\3wire    

sudo ./cube   

SPI example.

cd ~/Mosiwi_4x4x4cube\Pi4\c\examples\spi   

sudo ./cube   

If you update the execution file or modify the source code, you need to recompile the code.

sudo make
