HAL库F1编写 gpiob10，gpiob11，编写iic通信程序

以下是使用HAL库在STM32F1中编写GPIOb10和GPIOb11的代码：

首先，需要在头文件中包含相应的库：

#include "stm32f1xx_hal.h"

然后，在GPIO初始化函数中，设置GPIOB的引脚10和11为输出模式：

/* GPIOB Periph clock enable */
__HAL_RCC_GPIOB_CLK_ENABLE();

/* Configure PB10 and PB11 in output pushpull mode */
GPIO_InitTypeDef GPIO_InitStruct = {0};
GPIO_InitStruct.Pin = GPIO_PIN_10|GPIO_PIN_11;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);

在I2C通信程序中，需要初始化I2C并设置其参数：

I2C_HandleTypeDef hi2c1;

/* I2C1 clock enable */
__HAL_RCC_I2C1_CLK_ENABLE();

hi2c1.Instance = I2C1;
hi2c1.Init.ClockSpeed = 100000;
hi2c1.Init.DutyCycle = I2C_DUTYCYCLE_2;
hi2c1.Init.OwnAddress1 = 0;
hi2c1.Init.AddressingMode = I2C_ADDRESSINGMODE_7BIT;
hi2c1.Init.DualAddressMode = I2C_DUALADDRESS_DISABLE;
hi2c1.Init.OwnAddress2 = 0;
hi2c1.Init.GeneralCallMode = I2C_GENERALCALL_DISABLE;
hi2c1.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE;
if (HAL_I2C_Init(&hi2c1) != HAL_OK)
{
  Error_Handler();
}

然后，可以使用HAL_I2C_Master_Transmit()和HAL_I2C_Master_Receive()函数发送和接收数据：

uint8_t buffer[2] = {0x00, 0x01}; // data to be sent
uint8_t address = 0x50; // I2C device address
uint16_t timeout = 1000;

// Send data
if (HAL_I2C_Master_Transmit(&hi2c1, address, buffer, 2, timeout) != HAL_OK)
{
  Error_Handler();
}

// Receive data
uint8_t receivedData[2] = {0};
if (HAL_I2C_Master_Receive(&hi2c1, address, receivedData, 2, timeout) != HAL_OK)
{
  Error_Handler();
}
