STM32F4 MCU timer based "pulse train generation"

Job ID: 30743278

Budget: $30 – $250 USD

I need to program a "pulse train" based on a cortex-m4 MCU BOARD.
USING STM32CubeIde
The pulse train is generated through timer and timer interrupt.
The train pulse is variable in frequency
There must be a up ramp in frequency and down ramp frequency routine
I'm electronic engineer from Chile, have a bit of experience on progamming, BUT dont have time to get into all registers details on this MCU architecure and STM32CubeIde programming enviroment.
I can of course, try the provided code from the freelance on the board, and to have direct feedback contact with the freelancer who could do this, cheers !
