1. E LED All Mikroelektronika s development systems feature a large number of peripheral modules expanding microcontroller s range of application and making the process of program testing easier In addition to these modules it is also possible to use numerous additional modules linked to the development system through the I O port connectors Some of these additional modules can operate as stand alone devices without being connected to the microcontroller 7 MikroElektronika SOFTWARE AND HARDWARE SOLUTIONS FOR EMBEDDED WORLD waking ib simple EasyLED The EasyLED additional board is used to connect a development system port to LEDs Key features Parallel communication 8 LEDs 3 3V or 5V power supply voltage Figure 1 EasyLED additional board How to connect the board The EasyLED additional board can be easily connected to a development system via an IDC10 connector CN2 The CN1 connector is used to access the port pins the additional board is connected to How to use the board The EasyLED board is used to show the logic level on the development system ports When a pin is driven high logic 1 the appropriate LED connected to that pin is turned on Likewise if a pin is driven low logic 0 the appropriate LED will not illuminate Pi poji P3 P2 P5 P4 P P6 GND UCC wweo gl 66 42mm Figure 2 Dimensions of the EasyLED board Note When the EasyL2.
