Hi, How do i generate a delay of 50nS using C.is there any NOP instruction in ARM7.i dont want to use timer or interrupt.please help
Regards, Divya
i dont want to use timer or interrupt.please help
You don't want to use timer or interrupt. You must mean: It isn't possible to use timer or interrupt.
By the way 1: What do you want to delay 50 ns?
By the way 2: nS represents nano-Siemens (Siemens is a measurement of conductance, i.e. A/V or 1/ohm) or normally written 20 Mohm.
nS is nano seconds,i want a delay of 50nS as i want to genarate a frequency of 10 MHz at output pin of LPC2129. Please let me knoe where can i find the instruction set of ARM7 containing the machine cycle details of each instruction.
why you not just do searhc page ???
havve you try google it???
i tryed and get more 1000000 matcccches!!!
try www.simplemachines.it/.../arm_inst.pdf
10mhz is big speed yes
has CPU got pcm output???
nS is nano seconds,
No, that is what you want it to be. But it isn't. The internationally standardized symbol for the SI unit 'second' is still a lower-case 's'.
And you're thorougly misled about your choice of techniques. You say you "don't want" to use timers for this job, when timers are exactly what you should use for it. More to the point, you should be using some kind of hardware PWM generator fed off a timer. 20 MHz is way too high a frequency to be done by software-only methods, even on an ARM.
Sorry that I put my post before yours. Sometimes, my posts are not accepted immediately - the site complains about my mail address. When I come back later, I have to try to post again :(
