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...

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...
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...
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...
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...
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....
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...
Dear all,in a project which was assigned to me with the NUCLEO-H723ZG, I have multiple digital outputs, like PG12, PE9, PE11, PE14, PE13, PG14 et.c. mostly originating from the CN10 ZIO connector, where the pin names are intuitive, e.g. D7, D6, D5, e...
Hello..I am using STM32F429 Disco Board in which I am trying to interface finger print sensor NB65210 of next biometric using spi and I need to read the finger print data I have a example code in which it is reading properly but it is not reading whe...
