Posted on January 02, 2012 at 23:17I was considering a for loop delay but it just feels nasty, especially considering all the lovely stuff built into the chip...
But lets be realistic, the chip's timer could generate 250ns pulses, and could do so repetitively, but doing it once, and waiting for it to complete is going to take more cycles than using brute force. Figure writing an APB register is going to take at least 4 cycles each. If you're talking to one of those 16x2 LCD panels you'll need a host of other delays, and spin on busy loops.
Yes, software delay loops are ugly, which is why I suggest counting core cycles rather than hard coding something, or using an empty for() loop. There are clearly better solutions for micro/milli second delays.
