tristate "Timer GPIO example"

default n

depends on TIMER && DEV_GPIO
|
|
---help---
|
|
Enable the timer-gpio example. This example uses the timer interrupt
|
|
to periodically change the state of a digital output. The digital
|
|
output may be a relay, a led or anything else. This example can be
|
|
very useful to validate timer drivers by using a logic analyzer
|
|
connected to the digital output. This example differs from the timer
|
|
example because it waits on a sigwaitinfo() instead of using a signal
|
|
handler. This approach ensures a deterministic wake-up time when the
|
|
signal occurs.
