RFID based Door Access or Security Control System

A radio-frequency identification (RFID) based access-control or Security control system allows only authorised people to enter a particular zone of an office or building. Authorised people are provided with unique tags, using which they can access that particular area. This project is based on RFID, STM32f103C8 ARM Cortex-M3 development board, a 16x02 LCD module for displaying the status and a relay or servo motor for opening the door. Fig.1 depicts the block diagram RFID based Door Access or Security Control System.

Working

Now let’s see how our RFID reader and ARM Cortex-M3 controller will make Door Access control system. The basic working principle is very simple. When we place relevant RFID card near the MIFARE 13.52 MHz, the controller will read the data via SPI (Serial Peripheral Interface). If any card that match with the existing stored card in the code access will provided otherwise access denied. LCD 16x02 will display the all the messages like Swipe your card, Access Granted etc. Every time when user show his card the buzzer sounds.

Software and IDE’s used in the Project

   C- Language, Keil MDK ARM V5, Atollic TrueStudio for STM32

Getting Started With STM32 BluePill Part - Installation

In this Tutorial we are going to prepare our Arduino IDE to program STM32F103 using Arduino IDE.

Step 1: If you have not installed the Arduino IDE in your Laptop/PC please download and install the Arduino IDE by clicking the following link.

 Please Click Here to Download Install Arduino IDE.

    Note: Make sure to download your Corresponding OS software.

Step2: Extract Download ZIP file into your local C drive i.e. C:\

Step3: Open the folder and double click on Arduino.exe and you would see window as shown.

Step4: After the Arduino IDE open and download the required packages for the STM32 board. This can be done by selecting 

File -> Preferences.

Step5: Clicking on Preferences will open the below shown dialog box. In the additional Boards Manager URL text box paste the below link.

http://dan.drown.org/stm32duino/package_STM32duino_index.json

and press OK.

Step6: Now go to Tool -> Boards -> Board Manager. This will open the Boards manager dialog box, search for “STM32F1” and install the package that appears.

Step7: After Installation “STM32F1” package the Board Manager should like as shown.

Step8:  After the package, installation is completed. Go to Tools and scroll down to find the Generic STM32F103C series as shown below. Then make sure the variant is 64kFlah type, CPU speed is 72MHz and change the upload method to ST-Link.

Finally, we have completed the installation process. So we will see how to Blink on Board LED which is basically Hello World! programme.

Getting Started With STM32 BluePill Part - Introduction

Welcome to the Series of STM32103C8T6 Tutorials using STM32duino. In this Tutorial we are going configure our popular Arduino IDE to program STM32F103C8T6 Board popularly known as BluePill Module.

So Let's get started............................................

The BluePill Module is very powerful and low cost development board. The Features are Listed in the below one by one.

1.     STM32F103 Core Features

o    ARM 32-bit Cortex-M3 Core

o    72 MHz maximum Frequency

o    64 or 128 KB of Flash Memory

o    20 KB SRAM 

2.     Low Power 

o    Sleep, Stop and Standby Modes

o    VBAT supply for RTC and Backup Registers

3.     Temperature Sensor On Board

4.     SysTick 24-bit Down Counter

5.     7- Channel DMA Controller

6.     Peripheral Supported : ADC, SPI, I2C, UART and Timers.

7.     CAN

8.     USB 2.0 Full Speed Interface

9.     CRC Engine

10. 2 Watchdog Timers (Independent and Window)

Let's look at the differences between Arduino Uno and STM32F103C8T6 BluePill

Board	Arduino Uno	STM32 BluePill
Core	ATMEL	ARM Cortex-M3
Architecture	8 Bit	32 Bit
CPU Frequency	16 MHz	72 MHz
Flash Memory	32 KB	64 or 128 KB
SRAM	2 KB	20 KB
GPIO Pins	14	37
Peripherals	UART, I2C , SPI	UART, CRC, I2C, SPI, CAN, RTC, USB 2.0
ADC Pins	6	10

So by observing the above table, the STM32F103 BluePill is more powerful than compared to Arduino Uno.
