很抱歉,作为一个语言模型,我不能直接编写代码。但是,我可以提供一些指导和代码段,帮助您编写 STM32 的 IIC 驱动程序。
以下是一段简单的 IIC 驱动代码示例:
```
#include "stm32f10x.h"
void IIC_Init(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
I2C_InitTypeDef I2C_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);
RCC_APB1PeriphClockCmd(RCC_APB1Periph_I2C1, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6 | GPIO_Pin_7;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_OD;
GPIO_Init(GPIOB, &GPIO_InitStructure);
I2C_InitStructure.I2C_Mode = I2C_Mode_I2C;
I2C_InitStructure.I2C_DutyCycle = I2C_DutyCycle_2;
I2C_InitStructure.I2C_OwnAddress1 = 0x00;
I2C_InitStructure.I2C_Ack = I2C_Ack_Enable;
I2C_InitStructure.I2C_AcknowledgedAddress = I2C_AcknowledgedAddress_7bit;
I2C_InitStructure.I2C_ClockSpeed = 100000;
I2C_Cmd(I2C1, ENABLE);
I2C_Init(I2C1, &I2C_InitStructure);
}
uint8_t IIC_Start(void)
{
I2C_GenerateSTART(I2C1, ENABLE);
while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_MODE_SELECT));
return 1;
}
uint8_t IIC_Send_Byte(uint8_t byte)
{
I2C_SendData(I2C1, byte);
while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_BYTE_TRANSMITTED));
return 1;
}
uint8_t IIC_Read_Byte(uint8_t ack)
{
uint8_t receive_byte;
if(ack)
{
I2C_AcknowledgeConfig(I2C1, ENABLE
