Hello,I'm just started using a nucleo-h742x. I have configured the SPI and the Fatfs library using the default settings, the SPI speed was configured at speed below 1Mbit/s. The sys clock is below 100MHz.I always get disk_not_ready error when trying ...
Using the STM32F030RC, the program that originally ran at 0x800000 was moved to 0x8020000. After the move, SysTick_Handler() is no longer executed, causing HAL_Delay() to fail. Has anyone encountered this issue before?
Hi,I'm working on a STM32G030C8T6 based personal project and recently done a revision 2 to fix some annoyances and add some status LEDs. Programming and debugging is done via a STLink V3 and the SWD. I've encountered twice the same strange behaviour,...
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...
