Detailed Description

Typedef Documentation

HAL IRDA State definition.

Note

HAL IRDA State value is a combination of 2 different substates: gState and RxState (see IRDA State Code Definition).

gState contains IRDA 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 IRDA 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.

HAL IRDA State structures definition.

Note

HAL IRDA State value is a combination of 2 different substates: gState and RxState.

gState contains IRDA 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 IP initilisation status 0 : Reset (IP not initialized) 1 : Init done (IP not initialized. HAL IRDA Init function already called) b4-b3 (not used) xx : Should be set to 00 b2 Intrinsic process state 0 : Ready 1 : Busy (IP 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 IP initilisation status 0 : Reset (IP not initialized) 1 : Init done (IP 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.

Enumerator
HAL_IRDA_STATE_RESET	Peripheral is not yet Initialized Value is allowed for gState and RxState
HAL_IRDA_STATE_READY	Peripheral Initialized and ready for use Value is allowed for gState and RxState
HAL_IRDA_STATE_BUSY	An internal process is ongoing Value is allowed for gState only
HAL_IRDA_STATE_BUSY_TX	Data Transmission process is ongoing Value is allowed for gState only
HAL_IRDA_STATE_BUSY_RX	Data Reception process is ongoing Value is allowed for RxState only
HAL_IRDA_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_IRDA_STATE_TIMEOUT	Timeout state Value is allowed for gState only
HAL_IRDA_STATE_ERROR	Error Value is allowed for gState only
