Member Function Documentation

_timer_tick()

void RCInput_PRU::_timer_tick ( void  )

virtual

Reimplemented from Linux::RCInput.

Definition at line 47 of file RCInput_PRU.cpp.

Here is the call graph for this function:

init()

void RCInput_PRU::init ( )

virtual

Call init from the platform hal instance init, so that both the type of the RCInput implementation and init argument (e.g. ISRRegistry) are known to the programmer. (It's too difficult to describe this dependency in the C++ type system.)

Reimplemented from Linux::RCInput.

Definition at line 27 of file RCInput_PRU.cpp.
