CHAPTER 6
1 – WIRE® AND CAN COMBINED SYSTEM PROTOTYPE IMPLEMENTATION
6.1 Overview of Integrated System
The fully integrated prototype system presented here consists of the following: a
synthesizable 1 – Wire® Bus Master and a synthesizable CAN Controller implemented on the
Altera DE2 board; multiple CAN nodes using the design specified in Section 5.3.20; and
multiple 1 – Wire® slave devices. The complete prototype system is shown in Figure 6.1. The 1
– Wire® slave devices shown in Figure 6.1 are samples obtained through Maxim
Semiconductor. The CAN nodes shown in Figure 6.1 are based on Microchip application note
AN215 [47]. Table 6.1 shows FPGA resource utilization by the Altera DE2 Development and
Education board for the prototype CAN Controller and 1 – Wire® Master.
