Imagine my susprise when i discovered ST actually offers a DAB "software" for their 25KW evaluation board using stm32G474RE. And i go to ST's website.And the only downloadables are binary files and a lazy one page .pdf Am i missign something here? wh...

After a day of debugging, apparently HRTIM has minimum CR values, this means im not able to trigger any CR event close to the 0% of my scale, in my case this translates to a discontinuity in the lower end of my phase shift control. Is there any way a...

Im building some phase shifting control sensing for a Dual Active Bridge.Im using TIMA and TIMD (shown in pictures) in retrigerable single mode, both signals are triggered by sepparate CR from the master timer. https://community.st.com/t5/stm32-mcus-...

Trying to make a phase shift PWM for a DAB converter, i managed to do this exact functionality with normal TIM1 (Asynchronous mode), but im very very lost with HRTIM. I am able to produce complementary PWM signals for TIMA1 and TIMA2, and TIMB1 TIMB2...

Using stm32G474RE nucleo board and following this guide, i know my way around old "advanced" Timers from stm, im just getting started with HRTIMChanging PER register has effect in the PWM frecuency, but changing CMP1 doesnt do anything :(Im not able ...

This is a community, engage in a conversation, maybe people will help you along the debugging way.if you just drop your broken code for others to fix maybe youll be better hiring a freelancerhttps://www.fiverr.com/gigs/stm32If it was up to me ill try...

Derailing from the question , but, why do you need 2Mhz burst pulses?Are you doing radio or LCR measurement?

Working with magic numbers is not the way, code is for humans to read aswel as machines.Im chatgpting your question, i suggest you do the same, because i dont remember what every register does when you put a random 3 in it. void light_init(void) { ...

STSW-DABBIDIR , where is the code.

HRTIM has minimum CR values????

ADC measuring only high side of Centered Mode PWM (HRTIM)

synching HRTIM's TIMA and TIMB

HRTIM changing values of Compare register doesnt do anything
