- **TIM3_CH4 触发 ADC**: CubeMX 默认生成 `TIM_OCMODE_TIMING`，这不会产生 OC4REF 上升沿 → ADC 收不到触发。必须在 `tim.c` 中手动改为 `TIM_OCMODE_PWM1` + `Pulse = 500`。CubeMX 需选 CH4 为 "PWM Generation4 No Output" 并设 Pulse=500。

- **TIM4_TRGO 触发 ADC（当前方案）**: CubeMX 中 TIM4 无任何 PWM 通道，生成的 `MasterOutputTrigger` 为 `TIM_TRGO_RESET` → TRGO 无脉冲。必须在 `USER CODE TIM4_Init 2` 中写寄存器：

图4 典型两线总线配置
|
||||
|
||||
总线上发送数据的器件被称作发送器，接收数据的器件被称作接收器。控制信息交换的器件被称作主器件，受主器件控制的器件则被称作从器件。主器件产生串行时钟SCL，控制总线的访问状态、产生START和STOP条件。24CXX在I²C总线中作为从器件工作。
|
||||
|
||||
只有当总线处于空闲状态时才可以启动数据传输。每次数据传输均开始于START条件，结束于STOP条件，二者之间的数据字节数是没有限制的，由总线上的主器件决定。信息以字节（8位）为单位传输，第9位时由接收器产生应答。
|
||||
|
||||
## 起始和停止条件
|
||||
|
||||
数据和时钟线都为高则称总线处在空闲状态。当SCL为高电平时SDA的下降沿（高到低叫做起始条件（START，简写为S），SDA的上升沿（低到高）则叫做停止条件（STOP，简写为P）。参见图5。

## 位传输
|
||||
|
||||
每个时钟脉冲传送一位数据。SCL为高时SDA必须保持稳定，因为此时SDA的改变被认为是控制信号。位传输参见图6。

## 应答
|
||||
|
||||
总线上的接收器每接收到一个字节就产生一个应答，主器件必须产生一个对应的额外的时钟脉冲，见图7。

图7 I²C总线的应答
|
||||
|
||||
接收器拉低SDA线表示应答，并在应答脉冲期间保持稳定的低电平。当主器件作接收器时，必须发出数据传输结束的信号给发送器，即它在最后一个字节之后的应答脉冲期间不会产生应答信号（不拉低SDA）。这种情况下，发送器必须释放SDA线为高以便主器件产生停止条件。
|
||||
|
||||
## 器件寻址
|
||||
|
||||
起始条件使能芯片读写操作后，EEPROM都要求有8位的器件地址信息（见图8）。
|
||||
|
||||
器件地址信息由"1"、"0"序列组成，前4位如图中所示，对于所有串行EEPROM都是一样的。
|
||||
|
||||
对于24C02/32/64，随后3位A2、A1和A0为器件地址位，必须与硬件输入引脚保持一致。
|
||||
|
||||
对于24C04，随后2位A2和A1为器件地址位，另1位为页地址位。A2和A1必须与硬件输入引脚保持一致，而A0是空脚。
|
||||
|
||||
对于24C08，随后1位A2为器件地址位，另2位为页地址位。A2必须与硬件输入引脚保持一致，而A1和A0是空脚。
|
||||
|
||||
对于24C16，无器件地址位，3位都为页地址位，而A2、A1和A0是空脚。
|
||||
|
||||
器件地址信息的LSB为读/写操作选择位，高为读操作，低为写操作。
|
||||
|
||||
若比较器件地址一致，EEPROM将输出应答"0"。如果不一致，则返回到待机状态。
|
||||
|
||||
|
||||
图8 器件地址
|
||||
|
||||
## 器件操作
|
||||
|
||||
## 待机模式
|
||||
|
||||
EEPROM具有低功耗待机的特点，条件为：（1）电源上电；（2）接收停止条件及完成任何内部操作后。
|
||||
|
||||
## 存储复位
|
||||
|
||||
当协议中产生中断、掉电或系统复位后， $I^{2}C$ 总线可通过以下步骤复位：
|
||||
|
||||
（1）产生9个时钟周期。
|
||||
(2) 当SCL为高时，SDA也为高。
|
||||
(3) 产生一个起始条件。
|
||||
|
||||
## 写操作
|
||||
|
||||
## 1. 字节写
|
||||
|
||||
写操作要求在接收器件地址和ACK应答后，接收8位的字地址。接收到这个地址后EEPROM应答"0"，然后是一个8位数据。在接收8位数据后，EEPROM应答"0"，接着必须由主器件发送停止条件来终止写序列。
|
||||
|
||||
此时EEPROM进入内部写周期tWR，数据写入非易失性存储器中，在此期间所有输入都无效。直到写周期完成，EEPROM才会有应答（见图9）。

||||

||||

||||

## 13. 详细操作说明（续）
|
||||
|
||||
## 2. 页写
|
||||
|
||||
24C02器件按8字节/页执行页写，24C04/08/16器件按16字节/页执行页写，24C32/64器件按32字节/页执行页写。
|
||||
|
||||
页写初始化与字节写相同，只是主器件不会在第一个数据后发送停止条件，而是在EEPROM EEPROM收到每个数据后都应答“0”。最后仍需由主器件发送停止条件，终止写序列（见图10）。
|
||||
|
||||
接收到每个数据后，字地址的低3位（24C02）或4位（24C04/08/16）或5位（24C32/64）内部自动加1，高位地址位不变，维持在当前页内。当内部产生的字地址达到该页边界地址时，随后的数据将写入该页的页首。如果超过8个（24C02）或16个（24C04/08/16）或32个（24C32/64）数据传送给了EEPROM，字地址将回转到该页的首字节，先前的字节将会被覆盖。
|
||||
|
||||
|
||||
图10页写
|
||||
|
||||
## 3. 应答查询
|
||||
|
||||
一旦内部写周期启动，EEPROM输入无效，此时即可启动应答查询：发送起始条件和器件地址（读/写位为期望的操作）。只有内部写周期完成，EEPROM才应答"0"。之后可继续读/写操作。
|
||||
|
||||
应答查询流程见图11。

|
||||
|
||||
## 读操作
|
||||
|
||||
读操作与写操作初始化相同，只是器件地址中的读/写选择位应为"1"。有三种不同的读操作方式：当前地址读，随机读和顺序读。
|
||||
|
||||
## 1. 当前地址读
|
||||
|
||||
内部地址计数器保存着上次访问时最后一个地址加1的值。只要芯片有电，该地址就一直保存。当读到最后页的最后字节，地址会回转到0；当写到某页尾的最后一个字节，地址会回转到该页的首字节。
|
||||
|
||||
接收器件地址（读/写选择位为"1"）、EEPROM应答ACK后，当前地址的数据就随时钟送出。主器件无需应答"0"，但需发送停止条件（见图12）。
|
||||
|
||||
|
||||
图12 当前地址读
|
||||
|
||||
## 2. 随机读
|
||||
|
||||
随机读需先写一个目标字地址，一旦EEPROM接收器件地址和字地址并应答了ACK，主器件就产生一个重复的起始条件。
|
||||
|
||||
然后，主器件发送器件地址（读/写选择位为"1"），EEPROM应答ACK，并随时钟送出数据。主器件无需应答"0"，但需发送停止条件（见图13）。
|
||||
|
||||
|
||||
图13 随机读
|
||||
|
||||
## 3. 顺序读
|
||||
|
||||
顺序读可以通过“当前地址读”或“随机读”启动。主器件接收到一个数据后，应答ACK。只要EEPROM接收到ACK，将自动增加字地址并继续随时钟发送后面的数据。若达到存储器地址末尾，地址自动回转到0，仍可继续顺序读取数据。
|
||||
|
||||
主器件不应答"0"，而发送停止条件，即可结束顺序读操作（见图14）。

||||

||||

||||
