Resolved! What does an RTC on the STM32H7 do and how do you trigger an alarm?
hello it's me againI am a beginner and I have a question about the RTC, what is it ? it is an alarm something on the stm32? thank you.

Resolved! Get no HAL_ADC_ConvCpltCallback from ADC in DMA mode
Hi,I'm implementing ADC on a STM32F469HI board (in particular LIZARD board from ACTRON).I alreay implemented SPI comunication and UART (this one with DMA).Now the focus is to get ADC Reading implemented with DMA also.i set the timer 8 to trigger the ...
TSC and quadrature encoding in MCU Finder
Hello,I'm trying to have a list of MCU with TSC (touch sensing) and Timer comparator with quadrature encoding features but it looks like these are not listed in MCU finder or CubeMX.Is there a way to have this filtering?Thanks in advance,Filippo
I2C passiv Mode possible?
Hi,I try to sniff a I2C communication between multiple devices with my STM32G473.The controller should only listen passiv. Is this possible?For sure, I can always set the NACK-Bit to prevent sending an ACK and disable the Clock-stretching.And I can u...
Serial Numbers at production
Hi,im looking for some advice for using serial numbers at production. Its for a STM32H747 and we don't have NFC or BLis it normal practice to use your own serial numbers or use the MCU built in one?if using your own, at production whats a good way to...
UART LOOP using registers
Hi ! This is me again !I am able to send and receive separately but when try to do the loop, it doesnt work. What I am basically doing is when the full reception interrupt is set, I enable the transmission and as soon as the transmission is done, I d...
stm32g474 hrtimer issue
I meet a confused and unresonable issue about hrtimer with stm32g474mbt6.condition: 1).use timerA to generate 2 channel pwm. Channel 1 is set by CMP1, reset by CMP2; Channel 2 is set by CMP3, reset by CMP4;2). enable preload function, update when res...
Is it possible to to use same ADC in STM32 to sample at two different frequency simultaneously??
I have one ADC, whose channel 1 to 4 will start conversion at x time and channel 5 to 8 will start conversion at y time. May I know how to use the same ADC in an STM32 microcontroller to sample at different frequencies for different channels??
Safe clock speeds
I'm looking for information that will tell me the safe clock speeds for a voltage range. For example from 1.8v to 2.5v what is the highest clock speed I can run safely. usually there is a figure in the datasheet, but I can't find it. I'm using a ...
