Microcontroller no-OS Drivers

The majority of ADI's products are peripherals to a non-ADI digital engine (FPGA, Microprocessor, or Microcontroller). While there are major effort underway on FPGAs (Xilinx and Altera) and Microprocessors (running an operating system like Linux), the efforts on microcontrollers is fragmented due to the fragmented and diverse nature of the microcontroller market. The Goal of these projects (microcontroller/no-OS) is to be able to provide reference projects for lower end processors, which can't run Linux, or aren't running a specific operating system, to help those customers using microcontrollers with ADI parts.
