Hi all,

1. What options are available to check the size of my program code?

2.Since my application is time-critical, how can i measure the time taken for a function to execute? Also, what is the period for one instruction cycle?

3.How many instruction cycles will a C statement take, for example:

TIM1->OCBR += 0x9C40;

Warm regards,

TH Ong

Hi ongth60,

As RISC said is not easy to know the execution time for ARM instructions, so if you want to measure the time taken by a function, you can use the TIMER(at the beginning and the end of the section code) to do it.
