Hello I am using LPC1768 for a motor control application. The motor will be controlled with a series of pulses each of 2us wide. I use a asin function to calculate the time between two pulses. (The motor moves clock and anti-clock wise, hence a sin function is considered) when asin function is called, the code tends to break. ie it gets stuck at hardware handler routine. I believe the issue is with the use of asin function, although i am not sure about it. I am using inbuilt asin in math.h Can anyone kindly suggest me how to use a asin function on LPC1768. If anyone can provide me a small code for how to use it on LPC1768 would be of great help. I have tried the code on rowley crossworks and on Keil. Both seem to give the same error. But in simulator asin function is working fine. Kindly suggest. Regards Prakash
Take that sample code: http://www.codecogs.com/reference/c/math.h/asin.php > The motor will be controlled with a series of pulses each of 2us wide. > I use a asin function to calculate the time between two pulses. Do you also calculate asin() every 2us? You know, that calculation of this function takes up time?
