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 STM32F767ZI.STM32F767ZI has 512kbyte SRAM.However, if you use more than about 133kbyte for global variables etc., the program operation will be strange.Specifically, you will not be able to connect to the USB (VCP Port).I want to secure gl...
Hi!I am trying to interface the STM32F207's Ethernet peripheral with a KSZ8463 3-port managed switch. I'm using SPI as the management interface, so the MIIM is not connected (MCO + MDIO). So far, I have been able to run the lwIP HTTP server example o...
Have just spent a day or more going around in circles trying to connect the B-L475E-IOT01A Discovery to AWS using the code examples downloaded from the AWS console. Specifically the console reports the WiFi firmware need to be updated, despite having...
Hi everyone,I am working on adapting cellular connection example of X-CUBE-AWS to RaspberryPi and STMod+ is the cellular modem. There is no document which talks about what pins to STMod+ are mandatory.If there is any document which helps in porting o...
Using Nucleo H743ZI2semihosting with printf and CLI using sprintf I am unable to get the runtime library set to Reduced C to work using float/doubles. Standard C works with floats as expected. The initial stack size was 0x400, I have tried up to 0x16...
I'm programming a firmware with USB CDC support on an STM32F405. I noticed that when I connect the board to my system without working firmware running, all USB devices start glitching out. Every second, the mouse cursor stops moving for a moment. Thi...
Hi,Looking for ANY references to or better yet, a coded example of how to set up an STM32L processor with FreeRTOS and wake up from STOP0 mode on an RTC calendar event.FreeRTOS and sleep mode isn't an issue, that works fine. However anything more tha...
I use STM32F207VGT6 with noRTOS. And also I use fatfs uSD and USB drive same time.I have problem with f_open.Firstly I define filename arrays on the top of the file as the following order:When start of the program I controlled if uSDcard is mounted o...
Hi,I'm currently developing a board where I use STM32L433RC as my main unitof processment. This board will have an SD Card to store some data and later ontransfer it via UART. To achieve this, I must use an UART to Serial Portconverter.After some res...
Hi,Iam trying to write some data (i.e. 8 bytes) via the WriteMemory command of STM32L45xxx bootloader to the STM32's SRAM area (in particular to address 0x20000000). However when I connect to the device and look into the memory the data is not take...
