regarding the embeded softwares!!!!!!!!!!!!

[kotta]

Hi Friends,

Guys can any body please clear me for the following:

1.In general Any Product design is the combination of "Software+Hardware"?
If so can any body please clear me what is the role of "software-drivers-os"in
the real time senario.
2.It will be a great help if you can define using small example!!!!!!!!!
3.Also "which has got main control over other?",whether software controls hardware designs or viceversa######

regards,

of course,any embedded product is a comb of h/w and s/w
even devoce driver is nothing but software codes which will be added to the other source codes of the os deign
these device driver code will be talking to the hardware.they will have all the details,configurations of its particular device.
say for example,there is a product wherein there is a audio codec,touchpanel,usb driver etc.
take audioi codec,the chip has got lot of hardware settings to be done,i mean initialising,configuring the registers etc.these exercises are done by its device driver,which is nothing but a set of codes.similarly for touch panle,for usb will have its own device drivers.
all these device drivers will be added to the main os deisgn while creating the complete operating system.
both the hardware and software plays its own major roles in an embd sys.may be you can say the software controls the hardware.but harware is still the brain.


Cheers!

Hi Came,

Good to hear from you for my doubt!!!!!!!!

ya you are right!!!!!!

But one more thing is that "we oftenly hear that embeded processor and embeded controller?????"so what is you comment about these things!!!!You mean that all the controlling actions will be written in the form of a code like(c,c++) and inturn store that code in memory (like ROM or RAM)............

Also can you provide any related info,websites,material regarding these techie stuff.

Also can you please xplain me regarding the following:

"In general C,C++ languages has got the capability to directly interface with the hardware,which factor makes it so!!!!!!!!!"
