Function Documentation

__STATIC_INLINE int32_t ITM_CheckChar

(

void

)

ITM Check Character.

The function checks whether a character is pending for reading in the variable ITM_RxBuffer.

Returns

0 No character available.

1 Character available.

Definition at line 1621 of file core_cm3.h.

__STATIC_INLINE int32_t ITM_ReceiveChar

(

void

)

ITM Receive Character.

The function inputs a character via the external variable ITM_RxBuffer.

Returns

Received character.

-1 No character pending.

ch

)

ITM Send Character.

The function 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

[in]

ch

Character to transmit.

Returns

Character to transmit.
