I apologize for the lack of details. I am using a Nucleo G071RB board for both my Master and Slave boards. I posted my code in another post, but will include some specificities here.
Regarding the tutorial link posted, I had seen it, and when I try mimicking what he and many others did on their code I still fail to see an output on the SCL or SDA lines. That led me to think that I maybe initialized something wrong.
When considered I initialized things wrong, I took a look at my pin configuration in MX which I used to build my code's skeleton, and I tried creating my code with both GPIO Pull-up enabled and disabled as well as pairing it with external 5.6k resistors.
In my main, I have everything seen below before the control loop and the HAL_I2C_IsDeviceReady returns HAL_ERROR.
int main(void)
{
uint8_t buffer[3];
HAL_StatusTypeDef ret;
HAL_Init();
/* Configure the system clock */
SystemClock_Config();
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_I2C1_Init();
MX_USART2_UART_Init();
HAL_I2C_Init(&hi2c1);
HAL_I2C_MspInit(&hi2c1);
ret = HAL_I2C_IsDeviceReady(&hi2c1, (peripheralNucleoAddress), 10, HAL_MAX_DELAY);
if (ret != HAL_OK)
{
uint8_t message[27];
strcpy((char*) message, "Connection to board lost\n");
HAL_UART_Transmit(&huart2, message, strlen((char*) message), 5000);
//Transfer error in reception process
Error_Handler();
}
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
