STM32 - ADS1115 Single-Ended, Single-Shot, PGA & Data Rate Enabled HAL Library

A simple C library (STM32 HAL) for single-ended single-shot ADC measurments with ADS1115 module. (Tested on STM32F411RE)

This library includes several configurations such as PGA and data rate of ADS1115 and tested on STM32F411RE. Example project available.

• ! ADS1115_readSingleEnded(...) returns voltage as mV.

• Don't forget to check datasheet of ADS111x for detailed information: https://www.ti.com/lit/gpn/ADS1113

• Don't forget to check ads1115.h file.

Example Usage

Configure an I2C peripheral on CubeMX.

/* USER CODE BEGIN 2 */

  // ADS1115 Init
  if(ADS1115_Init(&hi2c1, ADS1115_DATA_RATE_64, ADS1115_PGA_ONE) == HAL_OK){
	  // Device found.
	  HAL_Delay(1500);
  } else{
	  // Device cannot found.
	  while(1);
  }

  float voltageRead;

/* USER CODE END 2 */

And,

 /* USER CODE BEGIN WHILE */
  while (1)
  {

	if(ADS1115_readSingleEnded(ADS1115_MUX_AIN0, &voltageRead) == HAL_OK){
		//Voltage successfully read.
	 }

 /* USER CODE END WHILE */

[Türkçe/Turkish] Kullanım Talimatı

• Adress değişkenini güncelleyin:

  1. ADDR PIN --> GND ise 1001000
  2. ADDR PIN --> VDD ise 1001001
  3. ADDR PIN --> SDA ise 1001010
  4. ADDR PIN --> SCL ise 1001011

• ADS1115_Init(...) fonks. ile I2C peripheral ve PGA ile Data Rate ayarlarını yapın. (HAL_OK veya HAL_ERROR)

• ADS1115_readSingleEnded(...) fonksiyonu ile single-shot okuma yapacağınız portu seçin ve float tipinde değişkeninizin adresini gönderin. (HAL_OK veya HAL_ERROR)

• Üçüncü adımdan sonra değişkeninizin içerisinde uygun katsayıyla çarpılmış gerilim değeri saklanacaktır.
