2 stm32地址在变形蛋白中不匹配

Question

我正在尝试与I2C通信2 STM32，我的配置如下：

7位寻址模式（无双地址，只有OAR1）

100khz速度

启用了ACK（在从属设备上）

已禁用ACK（在主设备上，因为主设备/从设备之间随时只能传输1个字节）

在主/从设备上，数据表都说GPIOB（PB6）作为AF的SCL和GPIOB（PB7）作为AF的SDA，但是PB8和PB9在Proteus中变成逻辑1，所以我使用PB8和PB9.Adress不匹配。是因为变形虫吗？

主密码：

#include "stm32f10x.h" // Device header 
#include "delay.h"

void pinConfig(void);

void i2c_Master_Config(void);

void sendAdress();

int main() {

  pinConfig();
  i2c_Master_Config();
  sendAdress();




  while(1) {}
}

void pinConfig() {

  RCC->APB1ENR |= 1<<21;//Enable I2C 1 clock
  RCC->APB2ENR |= 1<<2;//Enable GPIOA clock
  RCC->APB2ENR |= 1<<3;//Enable GPIOB clock 
  RCC->APB2ENR |= 1<<0;//Enable AFIO clock
  GPIOB->CRH |= 0x000000FF; //SCL ve SDA  AF Open Drain  SCL => PB8  
  SDA =>PB9  
}

void i2c_Master_Config() {

  RCC->APB1ENR |= 1<<21; //I2C 1 Clock Enable.  
  I2C1->CR1 |= (1 << 15);
  I2C1->CR1 &= ~(1 << 15);
  I2C1->CR2 |= 0x08; //36 Mhz peripheral clock.
  I2C1->CCR = 0x28; //100 khz clock  
  I2C1->TRISE = 0x09; //1/8MHZ= 125 ns  => 1000ns/125ns =8  => 8+1=9
  I2C1->CR1 |= (1<<0); //Peripheral enable.
}

void sendAdress() {

  volatile int temp;
  I2C1->CR1 |= 1<<8; //START bit.
  while(!(I2C1->SR1 & (1<<0))); //wait until start flag is set

  I2C1->DR = 0x0B; //7 bit adress.

  while(!(I2C1->SR1 & (1<<1))); //wait until addr flag is set
  temp = I2C1->SR2; //clear addr flag.
}

从站代码：

#include "stm32f10x.h" // Device header

void pinConfig(void);

void i2c_Slave_Config(void);

uint8_t data;

void I2C1_EV_IRQHandler() {

  volatile int temp;

  if(I2C1->SR1 &(1<<1)) { //wait until addr flag is set
    temp = I2C1->SR1; //clear addr  
    temp = I2C1->SR2; //clear addr
    GPIOA->BRR |= 1<<3;
  }
}

int main() {

  pinConfig();
  i2c_Slave_Config();

  while(1) {}
}

void pinConfig() {

  RCC->APB1ENR |= 1<<21; //I2C 1 Clock enable.
  RCC->APB2ENR |= 1<<2;  //Enable GPIOA clock
  RCC->APB2ENR |= 1<<3;  //Enable GPIOB clock 
  RCC->APB2ENR |= 1<<0;  //Enable AFIO clock

  GPIOA->CRL |= 0x00002000; //PA3 led.
  GPIOB->CRH |= 0x000000FF; //SCL ve SDA  AF Open Drain  SCL => PB8  SDA =>PB9
  GPIOA->BSRR |= 1<<3;   //Turn off the led.
}

void i2c_Slave_Config() {

  RCC->APB1ENR |= 1<<21; //I2C 1 Clock Enable.  
  I2C1->CR1 |= (1 << 15);
  I2C1->CR1 &= ~(1 << 15);
  I2C1->CR2 |= 0x08;
  I2C1->CCR = 0x28; //100 khz clock  
  I2C1->OAR1 &= ~(1<<15); //7-bit slave adress.
  I2C1->CR2 |= 1<<9; //Interrupt enable.
  NVIC->ISER[0] |= 1<<31; //i2c1 interrupt enable.
  I2C1->OAR1 = (0x05 << 1); //Slave adress
  I2C1->CR1 |= (1<<0); //Peripheral enable.
  I2C1->CR1 |= 1<<10; //ACK bit.
