AVR®: Splitting Functions Into USART.h and .c Files

 In this video:

  • Reference Tutorial on "AVR® Freaks: Modularizing C Code: Managing Large Projects (by Dean Camera)"
  • Grey out code that will not compile as part of your project (e.g. through #IFDEF), using Naggy (Available from the extension manager)
  • Move defines and function prototypes, used in relation to the USART, to a header file: USART_irq.h.
  • Move USART functions and variables to USART_irq.c.
  • Use of the Extern keyword is highlighted for global variables.
  • Add include files.
  • Add USART_irq.h to both main.c and USART_irq.h.
