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...
Resolved! STM32H743 Incorrect ADC measurement.
I am having some issues getting meaningful values out of my ADC. At the moment I am capturing ADC samples with the polling mode with the ADC pin being set to approximately 3.2v and 0v. When I check the sample results I am seeing around 20000 for capt...
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 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...
