STM32F0 LL库IIC第二地址配置错误

最近在做F0项目要用到多个IIC地址，使用Cube生成的LL库，第二地址进不了中断

F0版本：1.11.0

STM32CubeX生成的LL库代码为：

 1 static void MX_I2C1_Init(void)
 2 {
 3
 4   /* USER CODE BEGIN I2C1_Init 0 */
 5
 6   /* USER CODE END I2C1_Init 0 */
 7
 8   LL_I2C_InitTypeDef I2C_InitStruct = {0};
 9
10   LL_GPIO_InitTypeDef GPIO_InitStruct = {0};
11
12   LL_AHB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_GPIOB);
13   /**I2C1 GPIO Configuration
14   PB6   ------> I2C1_SCL
15   PB7   ------> I2C1_SDA
16   */
17   GPIO_InitStruct.Pin = LL_GPIO_PIN_6;
18   GPIO_InitStruct.Mode = LL_GPIO_MODE_ALTERNATE;
19   GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_HIGH;
20   GPIO_InitStruct.OutputType = LL_GPIO_OUTPUT_OPENDRAIN;
21   GPIO_InitStruct.Pull = LL_GPIO_PULL_UP;
22   GPIO_InitStruct.Alternate = LL_GPIO_AF_1;
23   LL_GPIO_Init(GPIOB, &GPIO_InitStruct);
24
25   GPIO_InitStruct.Pin = LL_GPIO_PIN_7;
26   GPIO_InitStruct.Mode = LL_GPIO_MODE_ALTERNATE;
27   GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_HIGH;
28   GPIO_InitStruct.OutputType = LL_GPIO_OUTPUT_OPENDRAIN;
29   GPIO_InitStruct.Pull = LL_GPIO_PULL_UP;
30   GPIO_InitStruct.Alternate = LL_GPIO_AF_1;
31   LL_GPIO_Init(GPIOB, &GPIO_InitStruct);
32
33   /* Peripheral clock enable */
34   LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_I2C1);
35
36   /* I2C1 interrupt Init */
37   NVIC_SetPriority(I2C1_IRQn, 3);
38   NVIC_EnableIRQ(I2C1_IRQn);
39
40   /* USER CODE BEGIN I2C1_Init 1 */
41
42   /* USER CODE END I2C1_Init 1 */
43   /** I2C Initialization
44   */
45   LL_I2C_EnableOwnAddress2(I2C1);
46   LL_I2C_DisableGeneralCall(I2C1);
47   LL_I2C_EnableClockStretching(I2C1);
48   I2C_InitStruct.PeripheralMode = LL_I2C_MODE_I2C;
49   I2C_InitStruct.Timing = 0x2000090E;
50   I2C_InitStruct.AnalogFilter = LL_I2C_ANALOGFILTER_ENABLE;
51   I2C_InitStruct.DigitalFilter = 0;
52   I2C_InitStruct.OwnAddress1 = 214;
53   I2C_InitStruct.TypeAcknowledge = LL_I2C_ACK;
54   I2C_InitStruct.OwnAddrSize = LL_I2C_OWNADDRESS1_7BIT;
55   LL_I2C_Init(I2C1, &I2C_InitStruct);
56   LL_I2C_EnableAutoEndMode(I2C1);
57   LL_I2C_SetOwnAddress2(I2C1, 182, LL_I2C_OWNADDRESS2_NOMASK);
58   /* USER CODE BEGIN I2C1_Init 2 */
59
60   /* USER CODE END I2C1_Init 2 */
61
62 }

对比HAL库，发现LL库在配置第二地址时，先使能了第二地址：

LL_I2C_EnableOwnAddress2(I2C1);

导致第二地址配置失败。

更改代码如下：

 1 static void MX_I2C1_Init(void)
 2 {
 3
 4   /* USER CODE BEGIN I2C1_Init 0 */
 5
 6   /* USER CODE END I2C1_Init 0 */

 8   LL_I2C_InitTypeDef I2C_InitStruct = {0};
 9
10   LL_GPIO_InitTypeDef GPIO_InitStruct = {0};
11
12   LL_AHB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_GPIOB);
13   /**I2C1 GPIO Configuration
