''In French'' : pour cette partie du projet, le choix s'est porté sur des multi leds de type L-132CB, le but est que tous les segments verticaux s'allument en meme temps et tous les leds horizontales s'allume une après l'autre. Pour les segments verticaux, si on chaîne les 5 leds du segment (série), on obtient du 10V sur les 5 leds... donc il faut prévoir pour le montage une alimentation 12V DC qui tienne 1A au minimum. Pour les segments horizontaux, c'est qu'une led par segment qui sera alimenté -> 2V par led.

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 : ULR = VF = 1.8V
    • average current : I = 20mA
  • the datasheet of the orange LED (see pages 3 / 4 / 5) indicates that :
    • conduction voltage : ULO = VF = 1.9V
    • average current : I = 30mA
  • the datasheet of the green LED (see pages 3 / 4 / 5) indicates that :
    • conduction voltage : ULG = VF = 2.2V

Formula

  • calculation of resistance R_LED_R :

Formula

  • voltage seens by the input of uC when it's a low state VDD_low :

  • Resitor seens by the input of uC when it's a low state RIN_low :

  • Resitor Pull-Up MAX :

R_{Pull-Up_{max}} = \frac{VDD - VDD_{low}}{I_L} = \frac{3.3 - 0.66}{2u} = 1.32 MΩ

Remark : the resistor must be more less that the R_PULL-UP_max - usually, the value of 10kohm is using for the resistor pull-up.

  • Current using when the switch is closed

Details arround the LED Segment

In French : pour cette partie du projet, le choix s'est porté sur des multi leds de type L-132CB, le but est que tous les segments verticaux s'allument en meme temps et tous les leds horizontales s'allume une après l'autre. Pour les segments verticaux, si on chaîne les 5 leds du segment (série), on obtient du 10V sur les 5 leds... donc il faut prévoir pour le montage une alimentation 12V DC qui tienne 1A au minimum. Pour les segments horizontaux, c'est qu'une led par segment qui sera alimenté -> 2V par led.

IN English: For this part of the project, the choice was carried on the multi LED L-132CB, the goal is that all vertical segment display in same time ans the horizontal leds display one after the others. For the vertical sgment, the leds will be chained in serial (5 leds -> 10V). For this assembly to provide for the power, a voltage of 12V. For the horizontal segment, there will have only 1 led supplied (2V).

to see more details, check the schematics part !!!

Datas

  • U_POW = Vcc = 12V DC --> choice concerning the power supply of LED segments
  • U_LED = 2V DC --> voltage on once leds
  • U_SEG = 5*U_LED = 5*2V = 10V --> voltage on once segment
  • I_LED = 20mA --> current use by once led

Calculation

Resistor in end line for vertical sgement

if the segment is alone, the end line resistor is of (example each element of the X letter) :

R_{1Seg} = \frac{Vcc - U_{seg}}{I_{LED}} = \frac{12V - 10V}{20mA} = 100 Ω

Power dissipated by the resistor Rseg:

P_{R_{1Seg}} = R_{1Seg} \cdot I_{Led}^2 = 100 \cdot (20mA)^2 = 40 mW

The choice for the resistor(s) value is : 100 Ω 1/4W

if the segments are linked by two, the end line resistor is of (example for the F, I, M, E letters) :

R_{1Seg} = \frac{Vcc - U_{seg}}{I_{LED_{Seg1}} + I_{LED_{Seg2}}} = \frac{12V - 10V}{20mA + 20mA} = 50 Ω

Power dissipated by the resistor Rseg:

P_{R_{1Seg}} = R_{1Seg} \cdot (2*I_{Led})^2 = 100 \cdot (40mA)^2 = 80 mW

The choice for the resistor(s) value is : 51 Ω 1/4W

Resistor in end line for horizontal sgement

if the segment is alone, the end line resistor is of (example each element of the M letter) :

R_{1LED} = \frac{Vcc - U_{seg_{LED}}}{I_{LED}} = \frac{12V - 2V}{20mA} = 500 Ω

Power dissipated by the resistor R_LED:

P_{R_{1LED}} = R_{1LED} \cdot I_{Led}^2 = 500 \cdot (20mA)^2 = 200 mW

The choice for the resistor(s) value is : 510 Ω 1/4W

if the segments are linked by two, the end line resistor is of (example for the F letter) :

R_{LEDs} = \frac{Vcc - U_{LED}}{I_{LED1} + I_{LED2}} = \frac{12V - 2V}{20mA + 20mA} = 250 Ω

Power dissipated by the resistor RLED_2:

P_{R_{LEDs}} = R_{LEDs} \cdot (2*I_{Led})^2 = 250 \cdot (40mA)^2 = 400 mW

The choice for the resistor(s) value is : 270 Ω 1/2W

if the segments are linked by three, the end line resistor is of (example for the E letter) :

R_{LEDs} = \frac{Vcc - U_{LED}}{I_{LED1} + I_{LED2} + I_{LED3}} = \frac{12V - 2V}{20mA + 20mA +20mA} = 167 Ω

Power dissipated by the resistor RLED_3:

P_{R_{LEDs}} = R_{LEDs} \cdot (3*I_{Led})^2 = 250 \cdot (60mA)^2 = 601,2 mW

The choice for the resistor(s) value is : 180 Ω 1W
