Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I am using STM32H747I-DISCO board, I want to use external SDRAM for bss and data region and I called the SDRAM initialization function inside the SystemInit() function and I tried with the debugger point it will go to hard fault when debugger point h...
I have spent over a week trying to get the USBX CDC ACM virtual com port to work on a STM32F7 family nucleo-144 board. I'm using an STM32F767 as a representative processor. I've tried multiple examples and approaches with no success. The device enum...
Hi, I got a Nucleo F103RB, and I am running the very same software I run on my Nucleo F7ZI, and I am getting this weird hard fault that always. I do not enable RTC, but right before the fault happens, the ICSR register tells there is a pending inter...
Hi together,after working more deeply into the link status register handling of Ethernet PHYs i did notice that the Link Status bit in the Basic Status Register (BSR) is Latched Low. That is also the reason why we need to read it twice. The ST driver...
Hello!I am working with the STM32H747i-Disco board, my aim is to create ethernet connectivity between the board and the PC, as a first step to send a ping from the PC to the STM32H747i-Disco and get a response. My cubeMX version is 6.2.1, the H7 firm...
I'm building up an app on the STM32L4R9-Discovery board that needs a lot of IO: UARTs, USARTs, I2C, SPI,RTC, FatFS on the SD Card and others. I'm pretty new to the STMCubeIDE and C/C++ world so I've build up several test apps that start for the Disco...
Hello, I have been working on eth creating a web page. I want to know if I should use php to connect to the database. (My database is on the website of the company I work for that collects sensor data.) I've tried it and it doesn't work. I tried usin...
Hi there,I am trying to interface to a s25fl128s EEPROM device. I understand that there is built in support for this SPI interface for STMCubeIDE. Can someone please point me in the right direction.In my search for a driver for the EEPROM I cam acr...
I have set all GPIOB ports as outputs and have an adjustable resistor on port PA1 which I’ve set as an analogue input to do an adc conversion to display a voltage output to three seven segment displays with each segment being connected from PB0 to PB...
I need to implement formatting of various media like SD cards or USB disks.With FATFS it was brain dead easy, it just worked without asking for the my shoe size and ultimate answer about universe and everything. With FILEX I need to provide just all ...
