HAL UART Reception type definition.

Note:: HAL UART Reception type value aims to identify which type of Reception is ongoing. It is expected to admit following values : HAL_UART_RECEPTION_STANDARD = 0x00U, HAL_UART_RECEPTION_TOIDLE = 0x01U,

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 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 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.

Enumerator:

HAL_UART_STATE_RESET	Peripheral is not yet Initialized Value is allowed for gState and RxState
HAL_UART_STATE_READY	Peripheral Initialized and ready for use Value is allowed for gState and RxState
HAL_UART_STATE_BUSY	an internal process is ongoing Value is allowed for gState only
HAL_UART_STATE_BUSY_TX	Data Transmission process is ongoing Value is allowed for gState only
HAL_UART_STATE_BUSY_RX	Data Reception process is ongoing Value is allowed for RxState only
HAL_UART_STATE_BUSY_TX_RX	Data Transmission and Reception process is ongoing Not to be used for neither gState nor RxState. Value is result of combination (Or) between gState and RxState values
HAL_UART_STATE_TIMEOUT	Timeout state Value is allowed for gState only
HAL_UART_STATE_ERROR	Error Value is allowed for gState only
