Hi, Blynkers.
I’m trying to synchronize a button with a zerocrossing signal every 4 Hz, but I’m having difficulty. I’m using the ESP-01 and I do not have the equipment to measure the signals. The serial is also not available for debugging.
The button circuit and zerocrossing are the same: http://www.dextrel.net/diyzerocrosser.htm
The code I tried is this:
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SimpleTimer.h>
//-------------------------------------------------------------------------------------------------------------------------------------------------------
char auth[] = "x6x2xdx4xex8x2xfxdx1x2xbx6x4xfxe"; //Autenticacao do App Blynk com o Android
//-------------------------------------------------------------------------------------------------------------------------------------------------------
// Redes Credenciadas
//char ssid[] = "MyASUS"; //Rede
//char pass[] = "DomoTest"; //Senha
char ssid[] = "MY3206"; //Rede
char pass[] = "xxxxxxxx"; //Senha
//-------------------------------------------------------------------------------------------------------------------------------------------------------
// Config para ESP-01
#define out_moc 0 //Pino de saida/acionamento do MOC - D2 da placa
#define wifi 1 //Pino do led ESP-01
#define zrc 2
#define sw 3
//-------------------------------------------------------------------------------------------------------------------------------------------------------
SimpleTimer application;
//-------------------------------------------------------------------------------------------------------------------------------------------------------
int dim; //Nível do atenuador - valor menor é mais brilhante
volatile boolean switch_button; // Boolean to store a "switch" to tell us if we have crossed zero
volatile boolean wifi_sts = false; //atribuído quando conectado a uma rede Wi-Fi
//-------------------------------------------------------------------------------------------------------------------------------------------------------
void check_application() //Funcao para tratar os comandos listados acima (porta XNOR)
{
if (switch_button == true)
digitalWrite(wifi, LOW);
else
digitalWrite(wifi, HIGH);
}
//-------------------------------------------------------------------------------------------------------------------------------------------------------
void setup() {
Serial.begin(9600); //Set de velocidade da serial do PC
delay(10);
Blynk.begin(auth, ssid, pass); //Autenticacao de App e rede a se conectar
delay(10);
pinMode(out_moc, OUTPUT); //Seta pino como saida para acionemento do MOC
pinMode(wifi, OUTPUT);
pinMode(zrc, INPUT_PULLUP);
pinMode(sw, INPUT_PULLUP);
digitalWrite(wifi, HIGH);
digitalWrite(out_moc, HIGH);
while (WiFi.status() == WL_NO_SHIELD) { //ou WL_CONNECTED
for (int j = 0; j <= 4; j++) {
digitalWrite(wifi, LOW);
delay(250);
digitalWrite(wifi, HIGH);
}
digitalWrite(out_moc, HIGH);
}
application.setInterval(250L, check_application); //Constante de tempo para chamar a funcao que trata dos pinos de entrada e saida
attachInterrupt(digitalPinToInterrupt(zrc), zero_cross_detect, FALLING);
Blynk.connect();
}
//-------------------------------------------------------------------------------------------------------------------------------------------------------
void zero_cross_detect() {
delayMicroseconds(50);
switch_button = (digitalRead(sw));
}
//-------------------------------------------------------------------------------------------------------------------------------------------------------
void loop() {
if (Blynk.connected()) {
if (wifi_sts != true) {
for (int i = 0; i <= 4; i++) {
digitalWrite(wifi, LOW);
delay (500);
digitalWrite(wifi, HIGH);
delay (500);
}
wifi_sts = true;
digitalWrite(wifi, LOW);
}
else {
Blynk.run(); //Roda aplicativo
application.run(); //Roda o tempo
}
}
else {
for (int i = 0; i <= 9; i++) {
digitalWrite(wifi, LOW);
delay (250);
digitalWrite(wifi, HIGH);
delay (250);
}
wifi_sts = false;
Blynk.connect();
}
}
What is wrong?
