Hi,
I found a problem in the OSA_TimeDelay() function defined in "KSDK_1.3.0/platform/osa/src/fsl_os_abstraction_bm.c".
void OSA_TimeDelay(uint32_t delay)
{
uint32_t currTime, timeStart;
timeStart = OSA_TimeGetMsec();
do {
currTime = OSA_TimeGetMsec(); /* Get current time stamp */
} while (delay >= OSA_TimeDiff(timeStart, currTime));
}
The condition inside the while loop makes the delay always 1 ms greater (because of the equality test) than the parameter passed to the function.
timer tick | delay = 3
0 | timeStart = 0
| 3 >= 0 // true, busy wait
1 | 3 >= 1 // true, busy wait
2 | 3 >= 2 // true, busy wait
3 | 3 >= 3 // true, busy wait
4 | 3 >= 4 // false, exit
Instead it should be:
while (delay > OSA_TimeDiff(timeStart, currTime));
Best Regards,
Derek
