TIYCam is an open-source IPC system powered by a Quad-Core ARM Cortex-A7 processor and a 2.0Tops NPU. By default, we have installed the JES application on TIYCam, which provides basic surveillance camera functions. It also enables users to develop AI video surveillance and other applications on their own.

└── README.mdTIYCam is ARM based CPU, and the host development is X86. To develop arm based application on x86 based PC, we need cross compile, and use the cross-compilation toolchain. Install gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf on Ubuntu20 as our development environment.
# Download toolchain
cd /opt
wget https://linksprite.s3.amazonaws.com/TIYCam/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf.tgz
tar xzf gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf.tgz # Set up environment variables
sudo vim /etc/profile # Append the following line to the end of the file
export PATH="/opt/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin:$PATH"Install NFS server for sharing file to TIYCam
sudo apt install -y nfs-kernel-server nfs-common -y
vim /etc/exports
# add the following line
/home/ubuntu *(rw,sync,no_root_squash,no_subtree_check)# restart nfs server
sudo systemctl restart nfs-serverTo demonstrate how to develop applications on TIYCam, let's take the "Hello World" example and walk through the entire process from compilation, packaging, installation, to execution.
