STM32中的IIC協議和OLED顯示屏

串口通信協議的缺點

串口通信通常需要至少三條線（TX、RX和GND），而 I2C 總線僅需要兩條信號線（SDA和SCL）；
串口通信僅支持一對一通信，而 I2C 總線支持多機通信，允許單個主機與多個從機設備進行通信；
串口通信通常無應答機制，而 I2C 必須有應答機制；
?串口通訊一般是異步通信，而 I2C 使用同步傳輸方式，數據在時鐘信號（SCL）的控制下傳輸。

?（上述中，黑體加粗是串口的一些特點，紅色是IIC的通信特點）

?IIC總線介紹

I2C總線，全稱Inter-Integrated Circuit（互連集成電路），是一種由Philips（現NXP半導體）公司在1980年代初開發的同步串行半雙工通信總線。

說明：一個主機可以控制多個從機，每個從機都有一個編號，通過編號指定從機的通信。?

IIC也支持多主多從，但是這個比較復雜不常用。

下節課介紹的OLED顯示器就是通過IIC進行通信的。

工作原理：?

主從關系：主器件用于?啟動總線傳送數據，并產生時鐘以開放傳送的器件，此時任何被尋址的器件均被認為是從器件。在總線上主和從、發和收的關系不是恒定的，而取決于此時數據傳送方向。

（主機的作用：啟動總線傳輸數據，產生時鐘用來開放傳送的器件）

數據傳輸：

如果主機要發送數據給從器件，則主機首先尋址從器件，然后主動發送數據至從器件，最后由主機終止數據傳送。
如果主機要接收從器件的數據，首先由主器件尋址從器件，然后主機接收從器件發送的數據，最后由主機終止接收過程。

時鐘同步：SCL用于數據的時鐘同步，確保主從設備之間的數據傳輸同步進行。

主要特點：

硬件簡單：I2C總線只需要?一根數據線和一根時鐘線?兩根線，總線接口已經集成在芯片內部，不需要特殊的接口電路。
多主機總線：I2C總線是一個真正的?多主機總線，如果兩個或多個主機同時初始化數據傳輸，可以通過沖突檢測和仲裁防止數據破壞。
在線檢測：I2C總線可以通過外部連線進行在線檢測，便于系統故障診斷和調試。
數據傳輸與地址設定：數據傳輸和地址設定由軟件設定，非常靈活。總線上的器件增加和刪除不影響其他器件正常工作。
負載能力：由于線路中電容會影響總線傳輸速度，I2C總線的負載能力為400pF，因此可以估算出總線允許長度和所接器件數量。

應用領域

????????I2C總線廣泛應用于各種設備和應用領域，例如傳感器、存儲器（如EEPROM）、顯示屏、溫度傳感器、實時時鐘（RTC）、擴展IO芯片等。

一般是軟件配置IIC：引腳進行分配。一般不設有硬件的IIC

總線上會掛載兩個上拉電阻的原因？（面試的時候可能會問到）

答：設備輸出的模式要配置成開漏輸出，只能輸出低電平，上拉電阻是為了輸出低電平。

IIC上的設備要配置的輸出模式？為什么？（面試的時候可能會問到）

答：要配置成開漏輸出，不能是推挽輸出。

原因：當沒有上拉電阻的時候，一個設備配置成推挽輸出且輸出高電平，另一個設備配置成開漏輸出，輸出低電平，兩個設備間會形成回路，嚴重時會造成設備燒毀。

若一個設備的輸出模式配置成開漏輸出，會發生什么？

答：由于總線上的上拉電阻作用，會強制將這一線路的電平拉成0伏，使開漏輸出不能正常的工作。是為了安全考慮，避免多個設備間的燒毀。因此，輸出模式要配置成開漏輸出。（一主一從的時候，推挽輸出和開漏輸出都可以，若配置成開漏輸出的時候，確保總線上有上拉電阻，要不無法輸出高電平。）

IIC總線時序

?起始信號

起始信號由主設備發起，用于通知總線上的所有設備即將開始數據傳輸。
當SCL為高電平時，SDA由高電平變為低電平，產生一個下降沿，表示起始信號的開始。

停止信號?

停止信號也由主設備發起，用于通知總線上的所有設備數據傳輸已經結束。
當SCL為高電平時，SDA由低電平變為高電平，產生一個上升沿，表示停止信號的開始。

?應答信號

每當一個字節的數據傳輸完成后，接收方會向發送方發送一個應答信號（ACK）或非應答信（NACK）。
應答信號在SCL的第9個時鐘周期（當SCL為高電平時）發送，傳輸一個字節是8位，需要八個時鐘周期。
當SCL高電平，若SDA線為低電平，則表示ACK（有效應答），表示接收方已成功接收該字節。
當SCL高電平，若SDA線為高電平，則表示NACK（非應答），通常表示接收方接收該字節沒有成功。

?讀寫時序

發送一個字節：SCL低電平期間，主機將數據位依次放到SDA線上（高位先行），然后釋放SCL，從機將在SCL高電平期間讀取數據位，所以SCL高電平期間SDA不允許有數據變化，依次循環上述過程8次，即可發送一個字節。
接收一個字節：SCL低電平期間，從機將數據位依次放到SDA線上（高位先行），然后釋放SCL，主機將在SCL高電平期間讀取數據位，所以SCL高電平期間SDA不允許有數據變化，依次循環上述過程8次，即可接收一個字節（主機在接收之前，需要釋放SDA）。

?一次完整的I2C時序

注意：IIC傳輸數據的過程中，?是?高位先行，與串口傳輸數據不同，串口傳輸數據是?低位先行。

模塊：OLED顯示器

?0.96寸OLED屏幕介紹

0.96 寸 4P（支持IIC協議） 7P（既支持IIC協議又支持SPI協議）OLED 屏幕模塊是一種顯示屏模塊，它包括一個 0.96 英寸的 OLED 顯示屏和四個引腳。這種OLED 屏幕模塊通常用于嵌入式系統和小型電子設備中，可以顯示文本、圖像和其他類型的信息。由于其小尺寸和低功耗，也常用于智能手表、健康追蹤器和其他便攜式設備中。

0.96寸OLED 參數

驅動芯片	SSD1306	分辨率	128 （橫向像素點）× 64（縱向像素點）
顯示尺寸	0.96 英寸	外形尺寸	27.5 × 27.8 （ mm ）
玻璃尺寸	26.7 × 19.26 × 1.4 （ mm ）	顯示區域	21.74 （ W ） × 10.864 （ mm ）
視角	全視角	工作電壓	3.3V ~ 5V
工作溫度	-20 ℃ ~ 70 ℃	存儲溫度	-30 ℃ ~ 80 ℃
使用壽命	>=16000 小時	支持接口	I2C（4p僅支持，7p支持SPI和I2C）

0.96OLED 屏幕模塊的優點有：

1. 高對比度和高亮度：OLED 屏幕模塊可以提供深黑色背景和明亮的字色，因此可以實現高對比度和高亮度的顯示效果；

2. 自發光：OLED 屏幕模塊不需要背光燈，因此可以實現更薄、更輕的設計；

3. 響應速度快：OLED 屏幕模塊的響應速度非常快，可以實現流暢的動畫和視頻效果；

4. 視角寬：OLED 屏幕模塊的視角非常寬，即使從不同角度觀察，圖像和文字也能保持清晰。

0.96OLED 屏幕模塊的缺點有：

1. 顯示壽命短：與 LCD 顯示屏相比，OLED 的顯示壽命相對較短，因為它的有機材料會隨著時間的推移而逐漸失效；

2. 顯示面積小：0.96 寸 OLED 屏幕模塊的顯示面積相對較小，因此不適合用于需要大屏幕的應用。

Software Configuration?

????????SSD1306 has internal command registers that are used to configure the operations of the driver IC. After reset, the registers should be set with appropriate values in order to function well. The registers can be accessed by MPU interface in either 6800, 8080, SPI type with D/C# pin pull low or using I2C interface. Below is an example of initialization flow of SSD1306. The values of registers depend on different condition and application.

????????SSD1306 內置有用于配置驅動 IC 操作的命令寄存器。復位后，應將寄存器設置為適當的值以確保其正常工作。這些寄存器可通過 MPU 接口以 6800、8080 或 SPI 類型（D/C# 引腳拉低）訪問，也可通過 I2C 接口訪問。以下是 SSD1306 初始化流程的一個示例。寄存器的值取決于不同的條件和應用。
