Detailed Description
Functions that access the ITM debug interface.
Macro Definition Documentation
◆ ITM_RXBUFFER_EMPTY
| #define ITM_RXBUFFER_EMPTY 0x5AA55AA5 |
Value identifying ITM_RxBuffer is ready for next character.
Definition at line 2152 of file core_cm7.h.
Function Documentation
◆ ITM_CheckChar()
| __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 2203 of file core_cm7.h.
◆ ITM_ReceiveChar()
| __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.
Definition at line 2184 of file core_cm7.h.
◆ ITM_SendChar()
| __STATIC_INLINE uint32_t ITM_SendChar | ( | uint32_t | 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.
Definition at line 2165 of file core_cm7.h.
Variable Documentation
◆ ITM_RxBuffer
| volatile int32_t ITM_RxBuffer |
External variable to receive characters.
