I am using STM32F051K6U7 HAL_GetTick()

[ck.1]

Hi ,

I am using STM32F051K6U7 for one of our project.

For Timing the HAL_GetTick() is low accuracy .

every 240 seconds there are 1 to 2 seconds off .

I am using a f0discovery board, so I am using internal RC occilator.

Is this expected or is there an errata to consider to fix it ?.

if you look in ds , see RC osz. about 1% , is about 2 s in 200 s, to expect. right ?
