STM32 MCUs Products

Resolved! I'm using a STM32F429I discovery with HAL drivers. Is there a sample code showing how to change the duty cycle of a timer working in PWM output mode at run-time? Thanks, Piero

Resolved! Registers aren't changing when written

Dear community,I am programming an ST32F407VE for the first time (I don't use the Cube32IDE though). First, I made an on board LED blink, so I am pretty certain that my toolchain and framework work properly. In the next step, I wanted to implement a ...

Resolved! DMA Interrupt every 1/4 buffer

Hi,I'm using a STM32G030 controller and I'm working with ADC Timer-triggered and DMA for storing the data. I need a quad-buffered DMA that generates an interrupt when 1/4 of the buffer has been filled. I'm not experienced with this so I'm asking some...

Resolved! Writing to STM32F767 battery backed SRAM, why can't I turn on PWR->CSR1 BRE

I need to write to the 4kB battery backed SRAM to hold information across power cycles, but it's not working! To be more specific:The debugger memory display shows the correct data in SRAM after a write.The data is read successfully at any time other...
