Display Autónomo para Elevadores

; Este artigo descreve sumariamente um sistema dedisplays universais e autónomos para equipar elevadores. Asolução desenvolvida consiste numa arquitectura distribuídade módulos inteligentes, munidos de displays gráficos do tipoLCD (liquid cristal display), ligados pelo barramento CAN(controller area network). Os módulos incluemmicrocontrolador PIC 18F, mem&oacu...

A Coprocessor for Traffic Scheduling and Schedulability Analysis in FTT-CAN

The low-processing power microcontrollers typically used within CAN nodes, usually place tight limits on the complexity and flexibility of on-line message scheduling systems. One solution to break this barrier is to transfer the scheduling task to a hardware implementation.A preliminary version of a traffic scheduling and schedulability analyser coprocessor is proposed in this pape...

Development and operation of a Bluetooth demonstrator

Wireless communications in distributed and/or embedded systems is an important research topic today. One of the emerging standards in this domain is Bluetooth. In this paper a demonstrator of embedded devices connected with Bluetooth is presented. The demonstrator is used to show the development technology available at our laboratory. So, besides the description of its operation, t...
