Logging buffer size (in bytes)
R2026bSize of pre-allocated buffer on target for signal logging during XCP external mode
Model Configuration Pane: Hardware Implementation / Hardware board settings / Target hardware resources / External mode
Description
Specify the number of bytes to preallocate for the signal logging buffer on the Arduino® hardware during XCP-based external mode simulation. The target uses this buffer to store logged signal data before transmitting it to the host. Specify a value large enough to accommodate all logged signals in the model.
The maximum number of log samples is approximately
floor(buffer_size / number_of_logged_signals). After the buffer
saves this many sample points, it wraps and further samples overwrite the older
ones.
If the buffer size exceeds the available RAM on the Arduino board, the deployment fails with the error ERROR: allocation of
logging memory failed. To resolve this error, reduce the buffer size or
decrease the number of logged signals.
Dependencies
To enable this parameter, clear the Set logging buffer size automatically parameter.
Settings
1000 (default)Enter a positive integer value representing the buffer size in bytes. The value must not exceed the available RAM on the target Arduino board.
