The Si10xx family is supported by the Si1000DK evaluation kit. This kit consists of the Si10xx mother board, Si1000-C test card (915 MHz, +20dBm, 64K program memory), USB debug adapter, cables, power supply, and documentation. The Si101x family is supported by the Si1010DK kit. It is the same as the Si1000DK with the exception that the test card is the Si1010-A test card (915 MHz, +20dBm, 16K program memory). There are numerous other test cards to support development. Refer to the Silicon Labs website for the latest test cards available. Silicon Labs’ EZMAC® media access control module is developed in C code for use with the company’s ISM transceiver products and MCUs to create low cost networks. With the EZMAC software, transceiver application designers are provided with a simplified interface to the physical radio layer that manages the delivery of signals and their associated packets from the transmitter to the receiver, between nodes. Wireless M-Bus is a metering networking standard that is quite common in Europe. Silicon Labs has a wireless M-Bus stack that has been fully qualified on the Si10xx/1x. The source code is freely available to customers under a simple software license agreement. The wireless M-Bus evaluation kit is an easy and effective way to demonstrate the low power characteristics of a virtual utility meter running the wireless M-Bus stack. The right hand side of the evaluation kit acts as a meter that contains a low power F930 MCU, a Si4431 transceiver, and a CP2400 LCD controller. The left hand side of the board is a measurement system that monitors the virtual meter and determines its power consumption. Using a wireless M-Bus metering GUI, the parameters of the meter can be easily adjusted (e.g. message size, RX/TX parameters, etc.) and the effect observed on the real-time power monitor display.
