• Install Library from https://github.com/nimaltd/STM32-PACK/raw/main/EE24/NimaLTD.I-CUBE-EE24.pdsc
• Add and enable it.
• Enable I2C.
• Select 'Generate peripheral initialization as a pair of .c/.h files per peripheral' on the Code Generator Tab.
• Generate code.
• Define a structure of EE24_HandleTypeDef.

• Call EE24_Init() and enjoy.

  solve F1 i2c problem

void HAL_I2C_MspInit(I2C_HandleTypeDef* i2cHandle) {

GPIO_InitTypeDef GPIO_InitStruct = {0}; if(i2cHandle->Instance==I2C2) { / USER CODE BEGIN I2C2_MspInit 0 / __HAL_RCC_I2C2_CLK_ENABLE(); // <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< add manualy / USER CODE END I2C2_MspInit 0 /

__HAL_RCC_GPIOB_CLK_ENABLE();
/**I2C2 GPIO Configuration    
PB10     ------> I2C2_SCL
PB11     ------> I2C2_SDA 
*/
GPIO_InitStruct.Pin = GPIO_PIN_10|GPIO_PIN_11;
GPIO_InitStruct.Mode = GPIO_MODE_AF_OD;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);

/* I2C2 clock enable */
__HAL_RCC_I2C2_CLK_ENABLE();

/ USER CODE BEGIN I2C2_MspInit 1 /

/ USER CODE END I2C2_MspInit 1 / } }

example:

include "ee24.h"

EE24_HandleTypeDef ee24; uint8_t data[1024]; int main(void) { ... ... ... if (EE24_Init(&ee24, &hi2c1, EE24_ADDRESS_DEFAULT)) { EE24_Read(&ee24, 0, data, 1024, 1000); } while(1) {

} }
