STM32f103 Peripherals Driver Lib

To make program on STM32 more easier, we packet every peripheral and module as a C++ class, mask operation steps instead of function-oriented interface.

e.g. How to use USART to send data

# include "USART.h"
USART com(1,115200);
void main()
{
    com<<"test string\r\n";
}

e.g. Use temperature and humidity sensor

#include "I2C.h"
#include "Si7021.h"
#include "USART.h"
#include "TaskManager.h"

USART log(1,115200);
I2C i2c1(1);
Si7021 tempHumi;

int main()
{
  tempHumi.Init(&i2c1);
  while(1)
  {
    tempHumi.Update();

    log<<"temperature:"<<tempHumi.GetTemperature()<<"\n";
    log<<"humidity:"<<tempHumi.GetHumidity()<<"\n";

    TaskManager::DelayMs(100);
  }
}

How to use

1. Install keil MDK 5 on windows
2. clone or download this project to your PC

git clone https://github.com/Neutree/STM32f103DriverLib.git

3. open example project in example folder with MDK5, compile and download to your board and run
4. There's three files you should pay attention: Main.cpp,Configuration.h,UserInterrupt.cpp, code your code and config configuration.

• Uncomment what you need in Configuration.h
• And every one driver have one folder, you should see the header file before you start code, there's some attention and doc in the header file.

Convention

File encode format

select UTF-8 without signature before you start code

keil->edit->configuration->editor->encoding
