Description
In French: Création d'une carte d'extension pour la carte Explorer (PROJET: Carte Explorer 16 & Exos sur les uC).
- V1: un montage permettra de simuler un carrefour routier, composer de 4 feux (RGB)
in English:
creation of one extansion board for the Explorer Board (see the links above)
- V1: assembly will allow to simulate a crossroad (4 fires (RGB))
Digram - Schematic
Part Calculation of Electronics Digram
LED's for crossroad
- the datasheet of the DSP implemented on the Explorer Board 16 (see pages 1 & 273) indicates that :
- output current of I/O : I = 10mA
- voltage I/O : VDD = 3.3V
- the datasheet of the red LED (see pages 3) indicates that :
- conduction voltage : VF = 1.8V
- average current : I = 20mA
Formula
- calculation of resistance RD
= 150mA
