HY-MiniSTM32V project examples

This archive includes a few example projects for the HY-MiniSTM32V board.
This board ships with some Keil Examples which are very buggy and mostly
unusable. The makefile-examples in this archive are all IDE-independet, they just use gcc/make.

libopencm3 examples are also included.
Until now most examples use SPL 3.5.0.

ssd1289+ads7843 TFT and Touchscreen examples are located in a different
repository. See here.

Included Example Projects (makefile, libopencm3):

* FreeRTOS 9.0.0, uses USART1 to do a "demo"
* SysTick + GPIO (blinky)
* USART1
* USART1 + printf (including newlib syscall _write())
* ADC1 polling
* PWM 3 channels (TIM3)
* PWM TFT backlight (TIM3)

Included Example Projects (makefile, SPL):

* Overclocking to 128MHz
* DWT CycleCounter
* USART1 with/without printf, with/without interrupts
* I2C1 with PCF8574
* CPU temperature reading via ADC
* CRC calculation (+emulation in C)
* EXTI, Buttons, LEDs
* SysTick Interrupt, delay and time measurement
* SDIO + Elm Chan's FatFS

Included Example Projects (Keil, SPL):

* Battery backed backup registers (RTC)
* Blinky
* Overclocking to 128MHz
* SSD1289 320x240px TFT Display
* USART1 + printf + floating point numbers
