operating system

[bexizuo]

Hi All,

is it required to run operating system on A13 ?
did somebody run A13 without OS ?
i mean for example flashing LED written in C directly like 8bit processors ...

i would sample GPIO in some periodical intervals at very high speeds and after it i would process data and i think that OS is having too much background jobs that will delay my program,

Kind regards,

Be aware that GPIO "very high speeds" may be a lot slower than you'd expect for a 1GHz cpu!!

How fast do you need?
