Ddr-Z8e

Ddr-Z8e is a device driver library for the Zilog® Z8-Encore!® microcontroller and its built-in peripheral hardware units. Some highlights are:

• Supports all MCUs compatible with the Z8 Encore! 642 family.
• Works with Zilog's free integrated development environment (ZDS II).
• Licensed under GPL.
• Drivers for IRQ, DIO, ADC, I2C, RS232, TIMER, SPI, WDT and FLASH
• Additional modules for binary number representation, ticker, serial LCD and basic integer to text conversion.
• Non-blocking, interrupt driven drivers for RS-232, I2C and SPI communication.
• Polled as well as interrupt driven A/D.
• All configuration parameters such as DIO-ports, alternative functions, baud rate, number of data bits, flow control, etc. configurable at runtime.
• Stand alone library having no external dependencies.
• Distributed as source code only.
• Highly configurable for various needs .
• Written in C (some minor pieces in inline assembler).
• Significant portions of the drivers implemented as inline code
  resulting in small footprint and high performance.
  
• Inline code can easily be reconfigured to use standard C-function
  calls assisting debugging.
• Configurable levels of assertation.
