I have 19 nucleo-u5a5zj-q, my program successfully run on 18 of then but fails for 1 (I did not modify the board nor connect anything else than the STLINK USB cable). Failure here means it detects a hardfault.Is there anything that I can use to verif...
my task is to use a ov2640 camera to capture photo for further using(yolo model input),I've configure DMA DCMI for this task. Now the situation is the sccb communication with ov2640 is ok but when I start DMA to get the photo data I can't get the ph...
Hi, I'm trying to add an external memory and i choose that chip because it can communicate with QSPI and there is no need for designing due the chip is SOIC-8 which i found a compatible board for it. I'm getting issues with the driver writing i'm get...
Hello guys,Can anyone help or provide me the boot sequence diagram of STM32H755xI which has dual-core (M7 and M4)?Thanks a lot !!!
Hi all! I am trying to communicate with the Nucleo-L4P5ZG via the LPUART1 peripheral over ST-LINK, however it doesn't seem to be transmitting or receiving anything. Following is my system clock initialization code (non-relevant parts cut out): #pragm...
Hi to all,I am moving to SPM32CubeIDE on Linux and, as a newby, I encountered a lot of problems.I started a new empty C++ project and I put all my flies and classes.I also included syscall.c file (renamed in syscall.cpp) as in it there are _seek(), _...
Such as the title，why is the function address in the vector table offset by 1 byte from the actual function address?In the vector table:Actually:andThis makes me wonder.
Hello,I am trying write a LoRa library to STM32F446VET7 in my application.In the LoRa E220-400T30S documentation, it tells me to set the UART settings for configuration mode to 9600 and 8N1 and to give 1 to M0 - M1 pins.After doing that I am trying a...
Hi guys, I'm fairly a newbie to stm32 so please forgive me if I make some mistakes, I'm trying to configure a driver code for a SPI FT812 NHD display on STM32G474VETx chipset, so far I've been able find a driver code and ported it over onto STM32, ho...
Using a stm32f303RE Nucleo board which has 4 (independent ?) ADC blocks.I'm trying to read a single channel from each of the 4 ADC under DMA simultaneously triggered from the same timer update event but I'm only getting about 30-40% of the data I'm a...
