ChibiOS Free Embedded RTOS

Hello,

I need to measure the execution time of a function ( function1() ) in milliseconds and print it. I wrote this code but it just gives me the system ticks. I need milliseconds.

systime_t start,stop, final;
start = chTimeNow();
function ();
stop = chTimeNow();
final = stop - start;
chprintf(chp, Time : %ld.%06ld\r\n",final);

Thank you for your help.

Hi,

CH_FREQUENCY should allow you to convert. The version in the repository has new macros for this. 2.6.2 should be released next week with the new macros.

Thanks for your reply,
I think CH_FREQUENCY is a defined constant. How can I use it?
Where is the repository?
