Seventh chapter LED will blink for me: Control the Light emitting diode

control the light and off of the LEDs. What we must know is: The ①led has two pins: GPB0 and GPB1, one of which is connected to the GPI0 port of the ARM processor, and the other pin is connected to the power VCC3 by a current-limiting resistor. When the GPI0 port is low, the LEDs produce a voltage difference at both ends, and the LEDs have

Class 1 lights up the first LED light

8.1 light LED Hardware connection diagram, According to the hardware diagram, when the output of the 175-pin gpio [0] is 0, the LED is on. When the output of gpio [0] is 1, the LED is off, the base address of the gpio register is 0x8000d000, which is the offset address of the used registers. First, select the gpio p

Seventh chapter LED will blink for us: control Light Emitting diode

Seventh Chapter LED will blink for us: Control Light Emitting diodeHow LEDs work: Light emitting diodes It is a kind of semiconductor diode that can convert electrical energy into solar energy.;often abbreviated toLED. LEDs, like ordinary diodes, are made up of aPNand a unidirectional conductivity. When a forward voltage is added to the

LDO current regulator for power LED

LDO current regulator for power LEDChallengeYou ' ve got a power LED? great! Build a flash light!What does the spec say? "voltage:3.6. 3.8 V, Power 3 W. " Okay. This means it draws some. Three Mignon cells give 4.5 V for at least three hours. So we add a resistor of 1.2 ohms and we are safe. If the LED runs at 3.6 v th
