Function Documentation

__STATIC_INLINE int32_t ITM_CheckChar

(

void

)

ITM Check Character.

Checks whether a character is pending for reading in the variable ITM_RxBuffer.

Returns

0 No character available.

1 Character available.

Definition at line 1739 of file core_cm3.h.

__STATIC_INLINE int32_t ITM_ReceiveChar

(

void

)

ITM Receive Character.

Inputs a character via the external variable ITM_RxBuffer.

Returns

Received character.

-1 No character pending.

Definition at line 1719 of file core_cm3.h.

__STATIC_INLINE uint32_t ITM_SendChar

(

ch

)

ITM Send Character.

Transmits a character via the ITM channel 0, and

• Just returns when no debugger is connected that has booked the output.
• Is blocking when a debugger is connected, but the previous character sent has not been transmitted.

  Parameters

  ch

  Character to transmit.

  Returns

  Character to transmit.

Definition at line 1698 of file core_cm3.h.
