ADS115 with ESP32 Lora V2

#1

Hello, I’m trying to use an ADS1115 on my ESP32 Lora V2, but I’m not getting it, could someone give me a tutorial with a sample code and the ports I should use, already test on 21 and 22 and also on 4 and 15.

Maybe you can find the routines related to esp32 + ads1115 on GitHub.

#3

yes, in Github there are several routines, but the biggest problem is when using in heltec lora v2, because when I call the display and the module everything works, but when I activate the lora automatically stops working the ads1115.

Can you show me your code?

This is a test code, it loads diplay and lora and then the ADS1115 and stops at it with the error message. If I disable LoRa in the parameter Heltec.begin(true, false, true, true, BAND); ADS1115 module works normally. Already tried several different ports to use as i2c.

#include “heltec.h” // Bibliteca LoRa e do Display

#include <Adafruit_ADS1X15.h>

Adafruit_ADS1115 ads;

// Frequência da comunicação

#define BAND 915E6

// Definicao de portas

String rssi;

// Exibe a logo da heltec

void logo()

void setupDisplay(){

// Inicia o Display

Heltec.display->init();

Heltec.display->flipScreenVertically();

Heltec.display->setFont(ArialMT_Plain_10);

// Exibe a logo

delay(1500);

Heltec.display->clear();

Heltec.display->drawString(0, 0, “Test” +String(ID1));

Heltec.display->display();

delay(1000);

}

//Configurações iniciais do LoRa

void setupLoRa(){

Heltec.begin(true, true, true, true, BAND); // Parametros: DisplayEnable, HeltecLoRa, Serial, PABOOST, BAND

// Inicia o LoRa

LoRa.setSpreadingFactor(8);

LoRa.setSignalBandwidth(125E3);

LoRa.setCodingRate4(5);

LoRa.setPreambleLength(8);

LoRa.setSyncWord(0xF1);

// LoRa.disableCrc();

//Ativa o crc (dígito de verificação)

LoRa.enableCrc();

delay(1000);

//LoRa.onReceive(cbk);

LoRa.receive();

}

void setup(){

//Chama a configuração inicial do display

setupDisplay();

//Chama a configuração inicial do LoRa

setupLoRa();

Heltec.display->clear();

Heltec.display->drawString(0, 0, “Esperando Master…”);

Heltec.display->display();

// sensors.begin();

// pinMode(TdsSensorPin,INPUT);

// dht.begin();

if (!ads.begin()) {

Serial.println("Failed to initialize ADS.");

while (1);

}

}

uint32_t t_enviaMaster=millis();

void loop(){

Serial.println(“Test Loop”);
dalay(1000);
}

Does anyone have any solution?

I2C0 be used for OLED, maybe you need to use I2C1. When you select the pin to connect to ADS1115, you can first use I2C_Scnner to detection.
