Drivers

Drivers in this repository are fully hardware independant Drivers primarily aimed at embedded world. All memories features are supported. Here are drivers of:

Presentation

This driver only takes care of configuration and check of the internal registers and the formatting of the communication with the device. That means it does not directly take care of the physical communication, there is functions interfaces to do that. Each driver's functions need a device structure that indicate with which device he must threat and communicate. Each device can have its own configuration.

Feature

This driver has been designed to:

• Only take care of the memory, not the communication with it
• Configuration is very simplified
• All memories features are covered
• Can communicate with virtually an infinite count of memories
• Different configurations can be used with different memories (no duplication of the driver needed)
• Direct communication with the memories, the driver has no buffer
• Can use the driver defines, enums, structs to create your own functions
• Contiguous memories can be used as 1 unique memory by the driver under certain conditions (I2C EEPROM only)
• Driver will take care of page access to minimize write process and save time
• Driver will take care of address composition of the data
