1. Outline of D2DL

Feature of D2DL

IT800 PLC modem technology developed by Yitran Communications Ltd. enables extremely robust PLC communication. The D2DL is a communication library which optimized for IT800. If you use the D2DL, you can get the communication which uses the IT800 feature and the unique identity at a maximum and also keep the coexistence with the other IT800 module.
It is all achieved by the interfaces with the upper layer (user application), such as the transmit/receive packet passing and the parameter setting, by the API functions (and callback functions). You can develop the communication application program easily by these API functions.
You can achieve one-chip solution using the available resource area of microcomputer, which the D2DL does not use, and create the system at low cost.
The D2DL runs on RTOS. We provide two types of edition, "Single Task Edition" and "Multi Task Edition". For more details, please refer to the D2DL User's Manual.
You can create the debug environment at once and debug efficiently using the project format of the RENESAS HEW (High-performance Embedded Workshop)
