STM32F103 IIC OLED program migration complete engineering code

This tutorial doesn't teach you the same thing OLED principle , What is? IIC Of , These concepts . Have studied SCM , We all know what is IIC, You may be a beginner , Yes IIC Conceptual understanding , But they are not proficient in application , It may also be used for the first time oled, The display effect is very good , I want to try it by hand , that , You're in the right place .

Nonsense , First, we will present the complete project documents to you , Then I will explain to you how to transplant this program .

Single chip model ：stm32f103c8t6

Pay attention to WeChat public number ： Guangyi electronics （dlrcclub）, reply ：IIC_OLED, A download link will pop up .

Before migration, let's introduce OLED How to configure the font taking software of the screen . If the configuration is incorrect , It will show a jumble .

The software we use is called PCtoLCD2002,

This software is very simple , You can get started in a minute without reading the tutorial , Let's focus on how to configure .

Refer to the configuration with red box on the picture to set , You can get the correct code .

Next, let's look at the program structure , Explain how to transplant this OLED Program .

 

In the program, we added IIC Drive and OLED The program , stay stm32 Medium hardware IIC It fails to work well , I use IO simulation IIC, Of course , This IIC I didn't write the driver , I can't remember IIC drive , Find one. IIC drive , I see. , Will call functions , I can transplant , So it will IIC 了 , You can't do everything yourself , Learn to stand on the shoulders of giants .

  open oled.c After the file, we can see that there are so many functions , Each function is different , There is a display of Chinese characters , There are numbers displayed , There is a display string , A wide range of functions , Beginners look really cool , But this is not what I also wrote , No matter which screen it is , Whether it's LCD、OLED still TFT The screen , Manufacturers will give you drivers , It's the same old saying , As long as you can transplant , Would call , Then you can finish most of the work , To be precise , I should have finished the work quickly .

After introducing the above functions, you may not be able to migrate them , Let's talk about how to transplant , In this project, we only need to use oled and iic That's enough . in other words , We're going to transplant oled.c、oled.h、iic.c、iic.h That's all right. .

Click the red, green and white Icon on the toolbar , Selected folder , And then click AddFiles, Just add the files you need to add , So what we add is .C file , An error will be reported when compiling , We also need to add .h file .

  Follow the steps in the figure , Put the corresponding file .h file

Add to it , In this way, we can see the corresponding .h The file was added to it .

In the corresponding c In the file, we add the header file , You can call the corresponding function .

  As shown in the figure above , We added oled.h and bsp_i2c.h The header file , You can call OLED_ShowCHinese Function , You can display the required text in OLED The screen .

The above explains how to transplant oled and iic Program , To quickly implement the tutorial of program presentation , Search for bilibili（ Guangyi is in action ） There are corresponding video content explanations , Welcome to like 、 Follow and forward .
