Posted on December 23, 2015 at 15:24hi, i'm currently learning how to program mcu by means of stm32+cubemx+hal, and i stuck with i2c interface, trying to write a byte to eeprom at24c04 with function
HAL_I2C_Mem_Write(&hi2c1, 0x50, 0x00, 8, &number, 8, 20);
* @param hi2c: pointer to a I2C_HandleTypeDef structure that contains
* the configuration information for I2C module
* @param DevAddress: Target device address
* @param MemAddress: Internal memory address
* @param MemAddSize: Size of internal memory address
* @param pData: Pointer to data buffer
* @param Size: Amount of data to be read
am i doing it right?
Tried expression
if(HAL_I2C_IsDeviceReady(&hi2c1, 0x50, 20, 500) == HAL_ERROR) HAL_GPIO_WritePin(GPIOD, GPIO_PIN_14, GPIO_PIN_SET);
led turns on immediately. ic connected accordingly to datasheet.
will gladly appreciate any information about my problem
