Hello everybody! I want to know "heartbeat" function of the eCos.
As far as I know, all Embedded Systems have CPU provided or external source of ticks, which is can be thought as "heartbeat" of system. And it can have different rates depending on h/w. I have read eCos reference and previous posts in ecos-discuss, but couldn't find which function is run on each tick? >From eCos book of Anthony J. Massa and eCos Ref I found that Clock, Alarm and Timer are attached to the Counter, so I thought some function of Counter (as it is basement for others) should have heartbeat handler function. Then I had a look to the source code and found void Cyg_Counter::tick( cyg_uint32 ticks ) function in packages\kernel\current\src\common\clock.cxx it seemed to be function which is called at each tick. Am I right? Basically I have 2 questions: 1) Which function is called on each heartbeat (=hardware provided source of ticks)? 2) Where should I specify (some assembler file...) which function to call on each heartbeat? Thanking in advence, Nodir. -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
