pub type HAL_UART_StateTypeDef = c_uint;Expand description
@brief HAL UART State structures definition @note HAL UART State value is a combination of 2 different substates: gState and RxState. - gState contains UART state information related to global Handle management and also information related to Tx operations. gState value coding follow below described bitmap : b7-b6 Error information 00 : No Error 01 : (Not Used) 10 : Timeout 11 : Error b5 Peripheral initialization status 0 : Reset (Peripheral not initialized) 1 : Init done (Peripheral not initialized. HAL UART Init function already called) b4-b3 (not used) xx : Should be set to 00 b2 Intrinsic process state 0 : Ready 1 : Busy (Peripheral busy with some configuration or internal operations) b1 (not used) x : Should be set to 0 b0 Tx state 0 : Ready (no Tx operation ongoing) 1 : Busy (Tx operation ongoing) - RxState contains information related to Rx operations. RxState value coding follow below described bitmap : b7-b6 (not used) xx : Should be set to 00 b5 Peripheral initialization status 0 : Reset (Peripheral not initialized) 1 : Init done (Peripheral not initialized) b4-b2 (not used) xxx : Should be set to 000 b1 Rx state 0 : Ready (no Rx operation ongoing) 1 : Busy (Rx operation ongoing) b0 (not used) x : Should be set to 0.
