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...

Unable to set up the ISM43340-M4G-L44-10CF WIFI Module on my STM32H7B3IDK board via SPI
I am trying to send and receive data from my STM32 board to the included WIFI module. However, the WIFI module doesn't seem to be responding. Instead, the only output I get are dots. Below, shows an excerpt of my code. I am trying to get the WIFI mod...
Resolved! STM32H750 FATFS Label , File and Directory errors
hi,I was trying to open Jpeg files from SD card and show them on LCD. LCD works, SDMMC works, I open the File System, I can read if its FAT32, I can read free space etc. But When I want to open a file or create a file on system it fails.* I always ge...
Resolved! Low cost micro for RGB
Hi,what are the lowest cost STM32 that support full graphics (static and minimal animation like a progress bar or spin control) with RGB/parallel interface (not DSI nor SPI)?Is there perhaps a comparison table that addresses such display-related requ...
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...

SPI NSS configuration in STM32H753 custom board
I have the main MCU serving as the master in the spi communication whose primary job is to transmit data over SPI lines to two slaves. If I choose hardware NSS signal configuration the IOC file assigns a default pin as the NSS signal for that SPIx pe...
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...
