LM35 HAL ADC
Greetings, STMCubeIDE STM32F407G-DISC1 I am tryiny to read a stable analog signal from LM35 output pin.However, I usually read zeros.The rest of the data also make no sense.Because the data range between each other is ve...

STM32H743VIT6 How to use SPI with DMA and without interrupt
Especially, I want to use the external ADC ADS8353IRTER.To get the data, it requires 48 CLK at 20MHz on SPI.We face lots of issues with the SPI linked with DMA (trigged by CC of timer).How to use SPI periph with 48CLK ?Up to now we need to send 3 tim...
STM32L476RG - SPI Communication
Hi, I am currently developing a battery management system (BMS) utilizing the STM32L476RG microcontroller (MCU) and the ADBMS6830 as the analog front end (AFE). Communication between the MCU and AFE is established via SPI. Since the AFE supports isoS...
reference voltage in STM32H743 for Calibration values TSCAL2 & TSCAL1 ?
What is the reference voltage did ST set in STM743 micro controller for temperature sensor for acquiring the Calibrated value TSCAL2 & TSCAL1 for 130*C and 30*C. Since during factory set How do ST Know What external voltage is going to come from desi...
NUCLEO-H755ZI-Q: Both CM4 and CM7 Resetting Due to WWDG (only configured to cm4)
Hello,observed that both the CM4 and CM7 cores are resetting (NUCLEO-H755ZI-Q), whereas it is expected that only the CM4 core should reset due to the Window Watchdog (WWDG2). For verification UART is configured in cm7 printing counter value. observe ...
Multi Channel ADC with DMA on a NUCLEO H753ZIT6
I'm just getting started with STM32 microcontrollers and I have been using the NUCLEO H753ZIT6. I was trying to learn how to use multiple channels of ADC's with DMA. I was able to get some data when I used a single channel ADC normally. But now I'm n...
writing flash memory failure
Hi everyoneI'm using a STM32F401RCT6 to control a valve actuatorThere is a counter of number of cycles for the actuator (RunTime), and when its value changes, the value of that counter must be stored in the memory for tracking and support.The actuato...
Resolved! STM32U5 Nucleo-U5A5ZJ-Q large SD card and 1 bit problem
HiI'm trying to connect an SD card to my Nucleo U5A5ZJ-Q board using SDMMC peripheral and use it with FatFS library. When I use 1GB card and 4 bit mode, everything works fine. By "works fine" I mean that:1. it passes this FatFS test: http://elm-chan....
Resolved! What is the maximum frequency for the FDCAN module in STM32G4
Looking through the RM0440 and the datasheet on the STM32G4,I can't find information on the maximum recommended frequency for modulCANFD.Or it may be the same as for microcontroller up to 170 MHz?HSE 8mhz -> PllM /2 -> PLLx85 /R /2 ... APB1 /1 -> PCL...
No error from null pointers
Hi,I have been making a lot of calls into null pointers and am quite surprised at the results. I am expecting hard failures when I make this mistake but instead it seems that things just keep going and it takes a long time to realize I failed to init...
