Hello,
I have a stm32f303k8 model microprocessor and collect gps data using skytraq gps module. However, although I change the baud rate of the microprocessor I can not change output rate of the Venus838LPx. So I want to write my code by using CUBEMx and KEIL and get GPS data when baudrate is fixed and output rate can be changed. For example, if 115200 baud rate is fixed as a baud rate, I want to collect 10 Hz 20 Hz 30 Hz 40 Hz GPS data. Can you help with this?
What, exactly, do you want help with?
What work have you done on this so far?
Where are you stuck?
Note that the stm32f303k8 chip and CUBEMx software are ST products - nothing to do with ARM or Keil.
So, for specific questions about the capabilities and/or use of the stm32f303k8 chip and CUBEMx software, you need to ask ST.

Keil have some "getting started" materials here:
