Posted on October 13, 2012 at 20:22when I build my project,an error ''User\main.c(12): error: &sharp136: struct ''<unnamed>'' has no field ''BSRR'' '' was appeared .

yes,I check the '' STM32F2xx_StdPeriph_Lib_V1.1.0 '' of STM32F2XX , it doesn't exits the BSRR but BSRRL and BSRRH.as follows:
//in the stm32f2xx.h
typedef struct
{
__IO uint32_t MODER; /*!< GPIO port mode register, Address offset: 0x00 */
__IO uint32_t OTYPER; /*!< GPIO port output type register, Address offset: 0x04 */
__IO uint32_t OSPEEDR; /*!< GPIO port output speed register, Address offset: 0x08 */
__IO uint32_t PUPDR; /*!< GPIO port pull-up/pull-down register, Address offset: 0x0C */
__IO uint32_t IDR; /*!< GPIO port input data register, Address offset: 0x10 */
__IO uint32_t ODR; /*!< GPIO port output data register, Address offset: 0x14 */
__IO uint16_t BSRRL; /*!< GPIO port bit set/reset low register, Address offset: 0x18 */
__IO uint16_t BSRRH; /*!< GPIO port bit set/reset high register, Address offset: 0x1A */
__IO uint32_t LCKR; /*!< GPIO port configuration lock register, Address offset: 0x1C */
__IO uint32_t AFR[2]; /*!< GPIO alternate function registers, Address offset: 0x24-0x28 */
} GPIO_TypeDef;
But all the Manual Reference incluces the latest mention the GPIOx_BSRR and tell the user how to use it .
No any document indicate the BSRRH and BSRRL .
And now,for the mismatch between the latest Manual Reference(RM0033) and its STM32F2xx_StdPeriph_Lib , I don't know how to solve it?
who tells me?
thanks.
