ESP8266 Arduino Library Diseqc

Satellite Positioner Diseqc

How to Use

Add header files

#include "Positioner.h"
#include "Diseqc.h"

Add EEPROM Management class and config sensor pin, diseqc pin, motor driver pins with Diseqc and Positioner class

//eeprom
ManageEEPROM MyEEPROM(512);

//DISEQC AND POSITIONER
uint16_t RECV_PIN = D2;   //GPIO4
uint16_t SENSOR_PIN = D1; //GPIO5
uint16_t EAST_PIN = D3;   //GPIO0
uint16_t WEST_PIN = D4;   //GPIO2
enum Error PositionerError = Error::none;
decode_results results;

Diseqc diseqc(RECV_PIN, 1024, kTimeoutMs);
Positioner positioner(SENSOR_PIN, EAST_PIN, WEST_PIN);

now decode diseqc message with diseqc.decode(&results) function

void setup() { 
  Serial.begin(9600);
  diseqc.begin(); 
}

void loop() {
  //...
  
//decode diseqc message.
  if (diseqc.decode(&results))
