Hi,I have been reading a few app notes but still a bit confused about some things...A custom board I am working with has an STM32U5G9VJT6Q MCU driving a DSI touch display. The PCB has QSPI and SDMMC but it does not have SDRAM.In the application, the ...
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...
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...
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...
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...
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...
