Timing issue when TIM10 interrupts HAL IWDG macro

I am using a STM32F746VET6 to drive time critical signals on up to 14 pins. I am bit banging these signals in the ISR. I was surprised to find after a benign change I started to have jitter in these signals. I tracked it down to the ISR firing during...

ST microcontroller Carbon footprint

Hi, I would like to know if it is possible to have the carbon footprint of ST32 microcontrollers. I searched around the websites but I cannot find this type of information.Thanks

SPI Transmitting and Receiving Data Not Matching

Hello,I control an ADC with SPI interface of the STM32F44 microcontroller. The ADC datasheet is in the link, https://intantech.com/files/Intan_RHD2000_series_datasheet.pdf . I set up global variables as read, write, and calibrate masks. The I call t...

QSPI External flash loader

"I want to make a QSPI flash loader and I'm watching ST's video series (it's a bit old). I'm using an STM32F446RE. Are the function prototypes shown in the video sufficient for the flash loader to work? Do you have any advice you can give me?"

How to correctly reassign RAM on STM32H755 for M4 to use AXISRAM and M7 to use SRAM1

I'm essentially trying to swap the RAM modules between the two cores on the STM32H755 so that all data in RAM used by the M7 is in SRAM1-3 and for the M4 is in AIXISRAM, but I'm observing some issues in startup behavior on the M4.From my understandin...

I have two Board with Same Micro Controller but with Different Version. Oldest Version Working Properly Fine But in Latest Version one am not available to flash the Code.Micro Controller STM32F439NIH6 VQ3 and VQ4 .Anyone have Same Issue Kindly Comment

I am using inbuilt RTC of STM32G941re , I am facing problem in interupt,when I set one min the alarm interupt comes after 30sec only not 1 minutes

The alarm time set properly but interupt ​in half time &sometimes I not came,please share if any one have idea

STM32F0 ADC externally triggered and software triggered simultaneously?

Hi,I need to measure 5 signals using the ADC. Out of the 5 signals, one is current (voltage across series shunt) which needs to be measured ONLY during transistor ON time, hence the ADC needs to be externally triggered by the PWM (OCREF). Other chann...

High sampling rate with ADC and no DMA

Hello All,I have some questions regarding the ADC of the STM32G071RBT6. Technically we can reach a conversion time of 400 ns if we use the internal ADC clock (35 MHz) and a sampling time of 1.5 cyc. OK, that's pretty good idealy.I am running my micro...
