Hi, With Dr. Butterfield's help, I've made the changes to implement the FIFO Queue using chain. I am not accustomed to coding for embedded systems, so I am not completely sure if I should be using malloc <https://richidubey.github.io/Strong-APA-Documentation/html/schedulerstrongapa_8c_source.html#l00179> or not.
Someone, please review the following changes: FIFO Implementaion and Queue traversal: https://richidubey.github.io/Strong-APA-Documentation/html/schedulerstrongapa_8c_source.html#l00159 The structure I have defined to be used with Chain_Control: https://richidubey.github.io/Strong-APA-Documentation/html/structCPU.html Thank you, Richi.
