Working with the STM32L052C8 using the HAL commands. I'm using the 'HAL_Delay()' command while developing, which is meant to be a delay in ms. I'm measuring HAL_Delay(1); to be 15ms. Checked with the data sheet and it says to have the Cortex System Timer at 4MHz which I have got by using Cubemx. Any ideas would be greatly appreciated, Thanks.
Presumably, when you say "the (sic) HAL" - you mean ST's HAL ?
If so, you should be going to ST for support with their code ...
They do supply the source - have you examined what it's doing ... ?
