ItsEddy ced7d5a34f [DeviceDriver] stm32: Remove explicity clear of RXNE flag
According to STM32 Manual, the USART RXNE flag will be clear automatically after
read to the USART_DR register[1], so the call to USART_ClearITPendingBit is
unnecessary.

bernard c45f5a2490 [Drivers] re-write serial framework. 2014-07-18 06:45:54 +08:00
Bright Pan 9691c659c8 It is a big patch for stm32f0x, see the fellow :
1. fix heap management for stm32f0xx(SRAM=8k)
    2. add USART1, USART2 driver for stm32f051R8
    3. fix finsh support for stm32f0x
    4. fix board components initial for stm32f0x and open debug msg
    5. add led driver(pc9) and test thread for stm32f0discovery board
    6. add init thread for stm32f0x do components initial
    7. add rcc initial for stm32f0x in rt_hw_board_init()
    8. add print rcc freq information function

the console output example is:
    SYSCLK_Frequency is 48000000HZ
    PCLK_Frequency is 48000000HZ
    HCLK_Frequency is 48000000HZ
    CECCLK_Frequency is 32786HZ
    ADCCLK_Frequency is 14000000HZ
    USART1CLK_Frequency is 48000000HZ
    I2C1CLK_Frequency is 8000000HZ
    SystemCoreClock is 48000000HZ
