Hey folks, I seem to have problem getting 1 second right. Board has no RTC so I've basically NULLed all the todc_XXX functions except todc_calibrate_decr.
Now question is, what value should I be assigning it to tb_ticks_per_jiffy ? I was able to dig up some info from the archive, and it read, =-=-=-FROM ARCHIVE =-=-=- You must find this value by yourself but a good starting point is your frequency in Hz (I think) Example of the code unsigned int freq = 28000000; tb_tick_per_jiffy = freq/HZ; tb_to_us = mulhwu_scale_factor(freq,1000000); =-=-=-END OF ARCHIVE =-=-=- I'm fine with working it out myself but where do I start ? My board has 33MHz OSC, so I've trie freq = 33 * 1000000 (where HZ is defined 100) but it turned out to be little short. I could have just tried few more trial and error, but I prefer knowing what I'm doing so.. :) Before I was trying it with 100 * 1000000 which had delays like 10:1. Now its only about 1.5:1. So, I guess I'm on the right track.... so can anyone please help me out here? Also, could anyone spill their brain on mulhwu_scale_factor() ? I've followed the code and ended up reading what seems to be a assembler. (Should have paid attention during the lectures :P) Any hint on this ? Thanks heaps.. Cheers, -- Daniel
