This example: R591LIB - name of application: app01.c
====================================================
Small I/O and CAN library for Phytec Rapid Development Kit (RDK)
for Philips 8xC591


Hardware requirements
=====================
Phytec RDK 591 with Philips 591


Software requirements
=====================
Phytec Flash Tools (part of RDK 591)
  www.phytec.com
Raisonance 8051 compiler system - EVAL version sufficient
  www.americanraisonance.com
Keil 8051 compiler system - EVAL version sufficient
  www.keil.com
Optional: Development Assistant-C by RistanCASE
  www.ristancase.ch


Tested using
============

Raisonance 51 Toolset version 6.1.1
Keil C51 Toolset version 6.00


Application description
=============================================
Raisonance specific files have their names prefixed with 'r'.
Keil specific files have their names prefixed with 'k'.
The same source files are used for both compilers.

DETAILS:  o Set CAN bus for 125kBit, receive all messages with       
            priority < 0x100                                         
          o Toggle LED with each incoming CAN message of             
            priority < 0x100                                         
          o Use lower 4 bits of dip switches to set a receive filter 
            on all messages with ID = 0x400 + (4-bit awitch value)   
          o Use higher 4 bits of dip switches to set the transmit ID 
            of messages send: ID = 0x400 + (4-bit awitch value)      
          o Transmit poti value in byte 1 of CAN transmit message    
          o Display received analog value on LED D1
