Hi Clive, ''dependencies within the library'' seems to be the problem. If I add the line, __IO uint32_t BSRR; /*!< GPIO port bit set/reset register, Address offset: 0x18 */; to the library structure, it breaks the normal GPIOX->BSRRL and GPIOX->BSRRH operations.

Web\$\begingroup\$ uxth is there because GPIO->BSRRL is (incorrectly) defined as a 16 bit register in your headers.
