CONFIG_SHELL_BACKEND_SERIAL_TX_RING_BUFFER_SIZE¶
Set TX ring buffer size
Type: int
Help¶
If UART is utilizing DMA transfers then increasing ring buffer size
increases transfers length and reduces number of interrupts.
Direct dependencies¶
SHELL_BACKEND_SERIAL_INTERRUPT_DRIVEN && SHELL_BACKEND_SERIAL && SHELL_BACKENDS && SHELL
(Includes any dependencies from ifs and menus.)
Default¶
8
