How to Create a New Project ?

• Run ./CreatePrj,sh in the Terminal
• This will appear user@os$ Enter the Name of the Project to Create
• Then Enter the project Name and a folder will be created with the requested name.

How to Import HAL in Project ?

• To import HAL Library in a new project you must copy the nessary .h & .c files from src/lib in your project's include directory.
• Once the files have been included then you can include them in the main.c freely.

How to used HAL Components ?

• If you want to use any componets such as (GPIO, ADC, UART etc) then you must a specific struct must be declared befor initalising the component.
• Suppose you want to use GPIO in your firmware then you must include the GPIO.h and use the following to enable GPIO.

// Before using the GPIO always make a valid PORT configuration this helps to keep the code in order
Port_config_t config_PortA = {
        .DDRx = &DDRA,
        .PINx = &PINA,
        .PORTx = &PORTA
    };

Pin_Init(&config_PortA, PIN_OUTPUT, 7); // configuring PIN 7 of PORTA as output 

How to Compile Code and Dump Firmware ?

Run the following Make Commands in the Project Directory:

• Run make -> To Compile Code.
• Run make clean -> To Clean / remove old binary files.
• Run make flash -> To Flash firmware to Board
