Help¶

RTT has no interrupt, so read have to be done using polling. This option sets time in milliseconds between two consecutive RTT read attempts when there is no input transfer for some time. When transfer is currently running ETH_POLL_ACTIVE_PERIOD_MS is used instead.

Direct dependencies¶

ETH_RTT && HAS_SEGGER_RTT

(Includes any dependencies from ifs and menus.)
