CONFIG_SHELL_BACKEND_SERIAL_RX_RING_BUFFER_SIZE¶
Set RX ring buffer size
Type: int
Help¶
RX ring buffer size impacts accepted latency of handling incoming
bytes by shell. If shell input is coming from the keyboard then it is
usually enough if ring buffer is few bytes (more than one due to
escape sequences). However, if bulk data is transferred it may be
required to increase it.
Direct dependencies¶
SHELL_BACKEND_SERIAL && SHELL_BACKENDS && SHELL
(Includes any dependencies from ifs and menus.)
Default¶
64
