With the J-Link RTT Viewer this channel can be used for multiple "virtual" terminals,Īllowing to print to multiple windows (e.g. The default implementation uses one channel per direction, which are meant for printable terminal input and output. Which can be used for different purposes and provide the most possible freedom to the user. RTT supports multiple channels in both directions, up to the host and down to the target, SEGGER RTT can be used with any J-Link model and any supported target processor which allows background memory access, Without affecting the target's real time behavior. With RTT it is possible to output information from the target microcontroller as well as sending input to the application at a very high speed It combines the advantages of SWO and semihosting at very high performance. < 0: Error.Ī Embedded Studio project for the emPower board that exposes I/O of a UART port can be downloaded here: File:RTL-UART-IO.zipĪ minimal implementation of the I/O functions could look like the below: Int _SEGGER_RTL_X_file_read(_SEGGER_RTL_FILE * stream, char * s, unsigned len) // Read data from file stream. Int _SEGGER_RTL_X_file_stat(_SEGGER_RTL_FILE *stream) // Get file status. When no standard I/O mechanism is implemented, the user can supply an implementation of the low-level routines to do output and optionally input. Note: This section applies to Embedded Studio V6.12 and later. Use user-supplied I/O mechanisms, such as output on a UART.

No code for formatting is required on the target, saving 1 - 3 kiloBytes of ROM. The debugger reads the format string and the parameters from the target and feeds it to its formatter to be printed. With host formatting printf output is processed by the debugger instead of on the target. On halt, the debugger reads and executes the operation command and parameters.Īvailable on all targets (Cortex-M, Cortex-A, Cortex-R, RISC-V) The J-Link reads the SWO pin while the target is running.Īvailable on all Cortex-M based systems with a SWO pin. The target application writes the output string to the ITM stimulus ports.

To use the full RTT API, the RTT Target Package needs to be added to the Embedded Studio project: RTT in Embedded Studio SWO

SEGGER Embedded Studio provides RTT printf() functionality automatically. Or its content should be encapsulated with #if !defined(_SEGGER_RTL_VERSION).

When using the SEGGER Runtime Library, this file should be removed from the project, Older projects might include SEGGER_RTT_Syscalls_SES.c or a similar file to override printf(). Suitable for applications with real-time requirements. The J-Link reads the buffer while the target is running. The target application writes the output string to a buffer in RAM. Use SEGGER Real-Time Transfer (RTT), which enables super fast output without halting the system. There are different mechanisms for different application requirements.
