  • Page 5: Introduction

    Development tools INTRODUCTION The dsPICPRO development system is a full-featured development board for Microchip dsPIC microcontrollers. It has been designed to allow students and engi- neers to easily exercise and explore the capabilities of dsPIC microcontrollers. It allows dsPIC microcontrollers to be interfaced with external circuits and a broad range of peripheral devices, allowing the user to concentrate on software develop- ment.
  • Page 6 Development tools SWITCHES The dsPICPRO development board features many peripherial devices. In order to enable these devices before programming, you need to check if appropriate jumpers or switches have been properly set. Switches are devices that have two positions - ON and OFF, which have a role to establish or break a connection between two contacts.

  • Page 7: Jumpers

    MikroElektronika dsPICPRO User’s Manual Development tools JUMPERS Jumpers, like switches, can break or establish a connection between two points. Beneath the plastic cover of the jumper is a metal contact, which makes a connec- tion when the jumper is placed between two disconnected pins.
