I2C Error while reading HTS221 temperature and humidity sensor on I-NUCLEO-LRWAN1 extension board. Hi all, I have been trying to read any data from HTS221 on extension board, and HAL I2C functions returns error.I try to read WHO_AM_I register but HAL_I2C_Memread function always returns timeout so error. Any suggestion would be appreciated, thanks.The simplest code to read WHO_AM_I register below#include "main.h"
#define DEV_ADDR 0xBF
#define WHO_AM_I 0x0F
I2C_HandleTypeDef hi2c1;
uint8_t Data = 0;
int32_t status = 0;
void SystemClock_Config(void);
static void MX_GPIO_Init(void);
static void MX_I2C1_Init(void);
int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_I2C1_Init();
status = HAL_I2C_IsDeviceReady(&hi2c1,DEV_ADDR,5,100);
status = HAL_I2C_Mem_Read( &hi2c1, DEV_ADDR, WHO_AM_I, 1, &Data, 1, 100);
HAL_GPIO_TogglePin( LED_EXT_SHIELD_GPIO_Port, LED_EXT_SHIELD_Pin );
while (1) { }
}
void SystemClock_Config(void)
{
RCC_OscInitTypeDef RCC_OscInitStruct = {0};
RCC_ClkInitTypeDef RCC_ClkInitSt
