To support application of B41 at such devices that keeps large volume of stored data as cordless phones and others, B41OS has file system “B41FFS” (on YAFFS basis) that uses Flash-memory as a data storage means. Optimizing compiler from C++ is developed on GNU C++ version 3.3 and adopted to architecture and instruction set of B41. Dev C++, ECLIPSE or Microsoft VC are used for source code editing and primary debugging. One of key elements of the software is continuously extending C++ radiochannel drivers library that support various configurations starting from rather simple “point-to-point” or “point-to-multipoint” to distributed systems with relaying of data packet via chain of radiocontrollers. Integrated development environment for assembler “IDE–B41” has text editor, assembler’s compiler and program simulator combined with single-step debugger.

Microcontroller B41 – universal platform for portable radio communication devices Applications Radioadapters – for Electricity Meters Wireless Telemetry The radio-adapters and re-translators represent the lower link in the data transmission network. Their main difference is as follows: the radio-adapters are the terminal devices, which can receive the data from the center only over the radio channel, transmit this data to the user devices over the RS-485 interface, receive from the user devices the confirmation of the command execution and transmit this confirmation to the center over the radio channel. the re-translators execute all the above listed functions and also can translate the commands to other devices (to re-translators or radio-adapters) over the RS-485 interface or over the radio channel GSM-communicator sequentially transmits these commands over the RS-485 interface to the “Radio-controller” module. The “Radio-controller” translates the commands to the “Radio-adapter” devices directly or through the re-translators, using the radio-interface. The radio-adapters transmit the commands to the user devices over the RS-485 interface. While addressing a concrete user device the latter gives the answer, which is translated through the radio-adapter, re-translator, radio-controller to the GSM-communicator. After transmission-reception of the whole set of commands the GSM-communicator transmits the results to the supervisor server over the GSM/GPRS channel. Any personal computer or GSM communicator can play the role of the master device. In the latter case, the supervisor server sends a set of the commands to the GSM-communicator through the GSM-GPRS channel. Each command represents a package with the data in the RS-485 wire protocol format The commands can be group or individual ones. For the individual commands the confirmation of execution is expected.. Wireless Telemetry System Kedah Electronics Engineering Kedah Electronics Engineering www.kedah.ru www.kedah.ru
