1.2?OLED屏幕

1.2.1?OLED簡介

? ? ?OLED（有機發光二極管）是一種顯示技術，它使用有機物質來發出光線。與傳統液晶顯示屏相比，OLED具有更高的對比度和更廣的視角。它沒有背光源，因此可以提供更深的黑色和更明亮的白色。

? ? ? ?OLED顯示屏由許多小的發光二極管組成，每個像素都可以獨立發光。這意味著OLED顯示屏可以實現真正的黑色，因為當像素關閉時，沒有任何光線發射。

? ? ?OLED具有快速的響應時間，因此在顯示動態圖像時可以提供更流暢的畫面。此外，OLED顯示屏擁有更寬廣的視角，因此無論從哪個角度觀看，圖像都能保持清晰和準確。

? ? ? OLED顯示屏還具有較高的能源效率。因為每個像素都可以獨立點亮，所以在顯示黑色時可以關閉相應的像素，從而節省能源。

? ? ? OLED技術可應用于各種設備，包括智能手機、電視、電子書閱讀器、車載顯示屏等。由于OLED顯示屏的薄度和柔性，它還可以用于可彎曲的顯示設備和可穿戴設備。

? ? ? ?然而，OLED顯示屏也有一些限制。首先，長時間顯示相同的圖像可能會導致“燒結”效應，即在屏幕上留下輪廓。其次，OLED顯示屏的壽命相對較短，使用壽命通常較液晶顯示屏更短。

? ? ? 總的來說，OLED技術在顯示領域具有許多優勢，如高對比度、廣視角和能源效率。隨著技術的不斷發展，OLED顯示屏將在各種設備中得到更廣泛的應用。

1.2.2 SSD1306介紹

? ? ? SSD1306是一款常用的單色OLED驅動芯片，由Solomon Systech Limited（國巨控股）設計和生產。它被廣泛應用于各種嵌入式系統和電子設備中，用于驅動OLED顯示屏。

? ? ? SSD1306采用低功耗、高對比度和快速刷新率的技術，使得顯示效果清晰亮麗。它具備128x64或128x32像素的分辨率，并支持四種顯示模式：正常顯示、反轉顯示、鏡像顯示和指令顯示。SSD1306還可以通過I2C或SPI接口與微控制器或其他外部設備進行通信。

? ? ? SSD1306內置了豐富的圖形繪制和文本顯示功能，可以輕松實現直線、矩形、圓形、位圖等圖形的繪制，以及字符、數字和自定義字體的顯示。它還提供了多種顯示模式和亮度調節選項，可以根據實際需求靈活控制顯示效果。

? ? ? SSD1306還具備內置的電源管理功能，支持低電壓檢測和電池電量顯示，可以實現智能電源管理。此外，它還支持多種硬件和軟件配置選項，方便用戶進行定制化開發。

? ? ? 總的來說，SSD1306是一款功能強大、易于使用的OLED驅動芯片，適用于各種嵌入式系統和電子設備中，能夠實現高質量、低功耗的顯示效果。

1.2.3 0.9寸OLED模塊介紹

筆者使用的0.9寸OLED模塊，驅動芯片為SSD1306，該模塊采用I2C驅動方式，對外有四個引腳：

1） GND: 電源地

2）VCC：電源正極，工作電壓區間為3~5.5V

3）SCL: I2C 時鐘引腳

4） SDA: I2C數據引腳

模塊的原理圖如下：

?2 FSP配置項目

2.1 配置項目參數

1）配置系統時鐘，根據硬件特性配置時鐘，筆者的板卡上的晶振為12M Hz

?2) 在Pins面板配置SCI3，使能I2C,并且配置IO端口

3）在Stacks面板創建i2c的object

?配置參數

?2.2 生成項目文件架構

點擊Generate Project content 按鈕，生成項目文件，其文件架構如下：

3 代碼實現

3.1 I2C的庫函數

3.1.1?R_SCI_I2C_Open()

函數原型：


fsp_err_t R_SCI_I2C_Open	(	i2c_master_ctrl_t *const 	p_api_ctrl,i2c_master_cfg_t const *const 	p_cfg )

函數功能： 打開I2C設備

返回值介紹：

FSP_SUCCESS Requested clock rate was set exactly.
FSP_ERR_ALREADY_OPEN Module is already open.
FSP_ERR_IP_CHANNEL_NOT_PRESENT Channel is not available on this MCU.
FSP_ERR_ASSERTION Parameter check failure due to one or more reasons below:
p_api_ctrl or p_cfg is NULL.
extended parameter is NULL.
Callback parameter is NULL.
Clock rate requested is greater than 400KHz
Invalid IRQ number assigned

3.1.2?R_SCI_I2C_Read()

函數原型：


fsp_err_t R_SCI_I2C_Read	(	i2c_master_ctrl_t *const 	p_api_ctrl,uint8_t *const 	p_dest,uint32_t const 	bytes,bool const 	restart )

函數功能：?從I2C設備執行讀取操作。當操作(成功)完成時，調用者將通過回調中的I2C_MASTER_EVENT_RX_COMPLETE收到通知。

返回值：

FSP_SUCCESS Function executed without issue.
FSP_ERR_ASSERTION The parameter p_ctrl, p_dest is NULL, bytes is 0.
FSP_ERR_INVALID_SIZE Provided number of bytes more than uint16_t size (65535) while DTC is used for data transfer.
FSP_ERR_NOT_OPEN Device was not even opened.

3.1.3??R_SCI_I2C_Write()

函數原型：


fsp_err_t R_SCI_I2C_Write	(	i2c_master_ctrl_t *const 	p_api_ctrl,uint8_t *const 	p_src,uint32_t const 	bytes,bool const 	restart )

函數功能：?對I2C設備進行寫操作，如果相關通道上已經有正在進行的I2C傳輸，則此函數將失敗。否則，將開始I2C寫操作。當用戶沒有提供回調時，該函數執行阻塞寫入。否則，寫操作是非阻塞的，并且當操作完成時將通過回調中的I2C_EVENT_TX_COMPLETE通知調用者。

返回值：

FSP_SUCCESS Function executed without issue.
FSP_ERR_ASSERTION p_ctrl, p_src is NULL.
FSP_ERR_INVALID_SIZE Provided number of bytes more than uint16_t size (65535) while DTC is used for data transfer.
FSP_ERR_NOT_OPEN Device was not even opened.

4.2 編寫測試函數

功能介紹：

1）讀取HS3003傳感器數據，包括溫度和濕度數據

2）轉換溫濕度數據為ASCLL

3）實時顯示溫濕度數據到OLED上

?1）數據轉換函數

2）顯示數據UI

3) 讀取溫濕度值，并顯示數據到UI

5 測試

編譯代碼，并下載到板卡中，UI顯示數據如下：

使用手接觸到傳感器，UI上的數據會有變化

FSP_SUCCESS	Requested clock rate was set exactly.
FSP_ERR_ALREADY_OPEN	Module is already open.
FSP_ERR_IP_CHANNEL_NOT_PRESENT	Channel is not available on this MCU.
FSP_ERR_ASSERTION	Parameter check failure due to one or more reasons below: p_api_ctrl or p_cfg is NULL. extended parameter is NULL. Callback parameter is NULL. Clock rate requested is greater than 400KHz Invalid IRQ number assigned

FSP_SUCCESS	Function executed without issue.
FSP_ERR_ASSERTION	The parameter p_ctrl, p_dest is NULL, bytes is 0.
FSP_ERR_INVALID_SIZE	Provided number of bytes more than uint16_t size (65535) while DTC is used for data transfer.
FSP_ERR_NOT_OPEN	Device was not even opened.
