This project is for driving TFT screen which has ILI9341 driver. The code written on cpp language with stm32f4 micro controller. The code background created on CubeMx program which provided by ST company The micro controller is STM32F407VGTX LQFP100 The program written in Cpp language with Keil-mVision IDE. To able to write Cpp code on STM32Fxx micro controllers do following

1) Create a project on CubeMX program 
2) Adjust necesarry peripherals and pinouts (UART, SPI, GPIO, TIMER etc)
3) Compile project 
4) For Cpp change main.c with main.cpp file 
5) Add extra files with the .cpp extension such as ILI9341_GFX.cpp
6) Compile project and run

1. VCC Connect to 3.3 pin
2. GND Connect to GND
3. CS Connect to PC5 as GPIO_Output
4. RESET Connect to PB0 as GPIO_Output
5. AO Connect to PC4 as GPIO_Output
6. SDA Connect to PA7 as SPI1_MOSI
7. SCK Connect to PA5 as SPI1_SCK
8. LED Connect to 3.3 pin

NOT: In the begenning of program there are 3 macro definition just un command the one which you want to test by default TEST_ANALOG_METER is on uncommand

//#define TEST_TFT_RINGMETER

//#define TEST_TFT_PIE_CHART

#define TEST_ANALOG_METER
