| - | The goal of this project (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. Here you can find a generic driver which can be used as a base for any microcontroller platform and also specific drivers | + | ==== Required Software ==== |

| - | The driver contains two parts: | + | |
| - | * The driver for the AD7980 part, which may be used, without modifications, | + | |
| - | * The Communication Driver, where the specific communication functions for the desired type of processor and communication protocol have to be implemented. This driver implements the communication with the device and hides the actual details of the communication protocol to the ADI driver. | + | |
| - | The Communication Driver has a standard interface, so the AD7980 driver can be used exactly as it is provided. | + | <WRAP round important round 80%> |
