Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
Hello sir,I am using STM32F779BI controller in my project.I am developing LwIP_HTTP_Server_Raw project my controller . I have written code for this I have done following Enable LWIP , DHCP ,HTTP .my code is working in network configuration perfactly ...
Hi,I'm developing a new project that will use a GSM module. On the PC, this presents as three (3) Endpoints e.g. COM5, COM6 & COM7. I need to communicate with the GSM module on at least two of the three endpoints using the AT command protocol.Will a ...
I traced the code flow and I found that the SPI flash should be formatted.I used an SD-Card and traced the code while it is mounted and knew that it searches in sector 0 for the record signature and the pointer to the partition sector. Then it reads ...
Hi everyone,I want to start using the H743ZI serial communication with an hyperterminal software but i am not able to compile my project. I am using the STM32Cube_FW_H7_V1.3.0 UART POLLING example as a reference but everytime i try to compile my proj...
Hello,I don't really have a problem, but I'm asking myself questions and I didn't succeed in synthesizing them and find answers on Google.Problem 1:Several tasks want to use the same peripheral, lets say SPI bus for example. What is the best way to p...
My work environment as below :1. Window 10 (Version 10.0.18362 Build 18362)2. Laptop processor: AMD PRO A12-8830B R73. My Discovery Board: STM32F407VG MCU 4. Driver Installed : en.stsw-link009 and Virtual Com port : VCP_V1.5.0_Setup_W8_x645. Codin...
I am wondering whether STM system bootloader enables internal UART pull ups? I guess it doesn't, but I can't find this in ST docs.My board does not have external pull ups on UART line and I want to avoid having RX pin floating.
Hi all!I intend to use USB and CAN on an STM32F072. The datasheet describes a 1KB SRAM buffer, 768B for USB and 256B for CAN.In CubeMX, when I set up the USB as a VCP, by default it sets 1000 bytes for "USB CDC Tx Buffer Size" and 1000 bytes for "USB...
Hi,we have a hex file coming from GCC which we cannot flash onto the MCU with our own flashing tool (F412 and L471 tested).While investigating, we found that after a shorter line all writing seems to fail silently (still receiving ACK).In the picture...
