Tecnicas antirebote en Botones

Tecnicas antirebote en Botones

esta Tecnica sirve para cualquier tipo de boton siempre y cuando uses la tecnica de poleo ( es decir que preguntes si se presiono)

esta tecnica de antirebote consiste de una simple bandera en el programa:

if (Boton es presionado && Variable ==0){

   Variable =1;

  ejecuta todo el codigo de boton presionado


}else if (Boton NO es presionado )
   {Variable ==0;}

ejemplo codigo CCS PIC

#bit Flag_CH0 = bandera.0

//--------------------------------------------- ejemplo touchcapacitivo

 if ( Is_touch() && !Flag_ch0 ){
     printf("tecla presionada \n\r");
     Flag_ch0=1;
   }else if (!Is_touch()){Flag_ch0=0;}

//-------------------------------------- ejemplo boton a tierra

 if ( !Input(Pin_B0) && !Flag_ch0 ){
     printf("tecla presionada \n\r");
     Flag_ch0=1;
   }else if (Input(Pin_B0)){Flag_ch0=1;}

void main(){
  Flag_CH0 =0; 
}


Nota la vaariable se debe inicializar en 0 inicialmente.

este codigo hace que el micro responda rapido y sin que entre en las rutinas boton presionado aunque se deje presionado el  boton, touch, o boton analogo. etc.

Raspberry Pi 1 Model A+ Pinout

Raspberry Pi 1 Model A+

The Raspberry Pi is a card-sized computer with an ARM processor that can run Linux. This item is the Raspberry Pi 1 Model A+ 512MB, which has 512 MB of RAM, an HDMI output, audio output, RCA composite video output (through the 3.5 mm jack), one USB port, and 0.1″-spaced pins that provide access to general purpose inputs and outputs (GPIO). The Model A Raspberry Pis are smaller and less expensive than the Model B Raspberry Pis. The Raspberry Pi requires a microSD card with an operating system on it (not included). The Raspberry Pi is very popular, with lots of example projects and information available online.

Compared to the Model A it has:

• More GPIO pins. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model A and B.
• Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
• Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
• Better audio. The audio circuit incorporates a dedicated low-noise power supply.
• Smaller neater form factor. We’ve aligned the USB connector with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes. Model A+ is approximately 2cm shorter than the Model A.

Raspberry Pi Model B 512MB RAM

Raspberry Pi 1 Model B

The Raspberry Pi® is a single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools. The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 512 Megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems.
