Figure 3-5 The AS Configuration Scheme
3.2 Bus Controller
The VEEK-MT comes with a bus controller using the Max II EPM240 that allows user to access the
touch screen module through the HSMC connector. This section describes its structure in block
diagram-form and its capabilities.
 Bus Controller Introduction
The bus controller provides level shifting functionality from 2.5V (HSMC) to 3.3V domains.
 Block Diagram of the Bus Controller
Figure 3-6 gives the block diagram of the connection setup from the HSMC connector to the bus
controller on the Max II EPM240 to the touch screen module. To provide maximum flexibility for
the user, all connections are established through the HSMC connector. Thus, the user can configure
the Cyclone IV E FPGA on the VEEK-MT to implement any system design.
