Based on the latest ARM Cortex-M3 STM32 development kit STM32 series of 32-bit flash microcontrollers breakthrough ARM Cortex-M3 kernel based on, which is a specifically developed for the application of embedded kernel. Cortex-M3 core: British ARM company pushing the kernel, dedicated to replacing 8 bit /16 bit microcontroller. Using the THUMB-2 instruction set, 32 bit performance, 16 bit density, compared with Cortex-M3, the ARM7TDMI kernel to 35%, the code is reduced by 45%. STM32 series products benefit from the Cortex-M3 architecture of a number of improvements, including improve performance at the same time and improve code density thumb-2 instruction set, greatly improve the response to interrupts and all the new features has industry Yun and power levels.

Software Examples

Our example from simple to complex, because the configuration of the LCD screen to explain profound theories in simple language, we can observe the experimental results, it is convenint.

GPIO test

output: Most simple example, light LED

Light LCD backlight: PWM test

LCD backlight boost circuit driven by PWM, because it is the hardware of the PWM, so as long as the good set up after not taking CPU resources, and simplify the hardware.

Light LCD screen

Use GPIO to simulate LCD hardware timing to drive LCD. Examples:

Display English string

Show Chinese characters

Display bitmap BMP

GPIO test two: input

Input experiment

Games

 

ADC test

Using the potentiometer on the plate to change the ADC input voltage.

PWM output test: Electronic piano

Use the timer PWM function to drive the speaker, by changing the ADC potentiometer, the sound of a different frequency.

I2C test: read and write EEPROM

I2C devices on read and write 24C02.

USB interface

Simulate a U disk.

SD card test

Ported the open source file system FatFS to STM32.

Serial communication experiment

UART0 query method

UART0 interrupt mode

CAN bus communication test

CAN bus transceiver experiment.

Timer test: interrupt mode

RTC test

External interrupt test

GPIO set to an external interrupt.

Intrusion detection test

Watchdog test

After observation of the watchdog, if the reduction of the dog is not fed

Software interrupt test

Real-time operating system test: uC/OS-II

Real time operating system uC/OS-II basic experiments, open 2 tasks.
