This chapter describes the hardware used in the dsPICDEM MCSM Development
Board. Topics covered include:
• Hardware Architecture
• PIM Configuration
• Board Connectors
• User Interface Hardware
The dsPIC DSC devices feature an 8-channel, high-speed PWM with Complementary
mode output, a programmable ADC trigger on the PWM reload cycle, digital dead time
control, internal shoot-through protection and hardware fault shutdown.
These features make the dsPIC DSC an ideal solution for high-performance stepper
motor control applications where full control of the full-bridge inverter is required.
Figure 3-1 provides a simplified block diagram of the development board hardware.
