The DolphinV4 API is a powerful abstraction layer for the DolphinV4 chip. It is provided as pre-compiled library (no source code) with an easy to use application programming interface (API). The DolphinV4 API uses the Keil PK51 tool set and the library is compiled with the C51 Compiler Version 9.05.

It offers the following features:

Supports both line powered and ultra low power applications
Full support of the EnOcean radio protocol stack with transmission and reception of EnOcean radio telegrams
Transmission and reception of custom data via UART and SPI interface
Digital and analog I/O configuration and handling
Flash manipulation routines
Control of the DolphinV4 chip power modes
Customizable HW Timer1 usage as counter with callback possibility or PWM control
Software timers
Application stack analysis
Preemptive priority scheduler enabling system task execution parallel to the application (can be turned on/off)
Integrated one level repeater functionality
Integrated SmartACK communication concept
Integrated Remote Management protocol
EnOcean serial protocol support (for ESP3)
