Detailed Description

simple kernel for running tool-libs based applications

also provides logging functionality

Member Function Documentation

idle()

void Kernel::idle

(

)

implement to not burn unnecessary cpu cycles

a simple sleep or 'wait for interrupt' will do

if running in a single thread, you probably want to call tick() in this method to advance the time

setTimeStep()

void Kernel::setTimeStep

(

uint16_t

dt_us

)

implement in simulation backend to be able to speed up time.

takes step size in microseconds. default is 1000

reset()

void Schedule::Recurring::Registry::reset ( )

inlineinherited

reset calling times of all registered functions

this may be necessary when 'global time' jumps backwards e.g. when 'global time' is actually 'experiment time' and the experiment is restarted
