I have two Arduino boards. One is connected to an IR transmitter and the other is connected to an IR receiver.
I have the IRremoteESP8266: IRrecvDumpV3 application running on the receiver board which seems to work ok, as when i press one of my IR remote controls, it prints out consistent data based on each button press.
However, I am trying to a create an application on the transmitter end which for a start has hard-coded hex string as commands there to test in a loop, which get converted to uint64 values and sent to the sendElitescreens() function and transmitter as below. The uint64 values are correct before sending.
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <ESP8266SSDP.h>
#include <uri/UriBraces.h>
#include <IRremoteESP8266.h>
#include <IRsend.h>
#include <OneWire.h>
#include <DallasTemperature.h>
const uint16_t kIrLed = 5; // ESP8266 GPIO pin to use. Recommended: 4 (D2).
int LED = 4; // Assign LED pin i.e: D2 on NodeMCU
// GPIO where the DS18B20 is connected to
const int oneWireBus = 2;
// Setup a oneWire instance to communicate with any OneWire devices
OneWire oneWire(oneWireBus);
// Pass our oneWire reference to Dallas Temperature sensor
DallasTemperature sensors(&oneWire);
IRsend irsend(kIrLed);
void setup() {
sensors.begin();
pinMode(LED, OUTPUT);
irsend.begin();
Serial.begin(115200);
}
uint64_t stringToUint_64(String value) {
int stringLenght = value.length();
uint64_t uint64Value = 0x0;
for(int i = 0; i<=stringLenght-1; i++) {
char charValue = value.charAt(i);
uint64Value = 0x10 * uint64Value;
uint64Value += stringToHexInt(charValue);
}
Serial.print("string to int is");
Serial.println(uint64Value);
return uint64Value;
}
int stringToHexInt(char value) {
switch(value) {
case '0':
return 0;
break;
case '1':
return 0x1;
break;
case '2':
return 0x2;
break;
case '3':
return 0x3;
break;
case '4':
return 0x4;
break;
case '5':
return 0x5;
break;
case '6':
return 0x6;
break;
case '7':
return 0x7;
break;
case '8':
return 0x8;
break;
case '9':
return 0x9;
break;
case 'A':
case 'a':
return 0xA;
break;
case 'B':
case 'b':
return 0xB;
break;
case 'C':
case 'c':
return 0xC;
break;
case 'D':
case 'd':
return 0xD;
break;
case 'E':
case 'e':
return 0xE;
break;
case 'F':
case 'f':
return 0xF;
break;
}
return 0;
}
void loop() {
String up_command = "FDA2256";
String down_command = "FBA1136";
String stop_command = "FEA3387";
Serial.println("In loop - sending commands ..");
// Send each screen command and wait for 4 seconds
digitalWrite(LED, HIGH); // turn the LED on
//Serial.println("Up");
//Serial.println(up_command);
irsend.sendElitescreens(stringToUint_64(up_command));
digitalWrite(LED, LOW); // turn the LED off
delay(4000);
digitalWrite(LED, HIGH); // turn the LED on
//Serial.println("Down");
//Serial.println(down_command);
irsend.sendElitescreens(stringToUint_64(down_command));
digitalWrite(LED, LOW); // turn the LED off
delay(4000);
digitalWrite(LED, HIGH); // turn the LED on
//Serial.println("Stop");
//Serial.println(stop_command);
irsend.sendElitescreens(stringToUint_64(stop_command));
digitalWrite(LED, LOW); // turn the LED off
delay(4000);
}
The dump received on the IRrecvDumpV3 doesn't make any sense unfortunately. The hex values don't match and are changing all the time as below.
Am I doing something fundamentally wrong here? Thanks in advance for any support.
