Hi everyone,in my project i have a define that is used to change the "version" of the project.the define is always used on one byte, for example #define VER 0x36, if I change it to 0x37 I see only 20 differences in the .bin (only where is used), but ...
Hi, I'm using STM32H755 nucleo board. I'm running FREERTOS on core M7 and bare metal on M4. I have been sending debug messages through USART3. It has been working ok, but sometimes messages from different tasks are overlapping. I want to change code ...
TLDR; STM32Ethernet has udp problems where it freezes for 20 seconds after sending data for 20 seconds and 60 seconds. After this it runs smoothly. However i'd like for it to not freeze twice as it is important the data gets sent asap.Hi, i am using ...
I am using STM32H573 and trying to enable ethernet. I have used the below article for it:https://community.st.com/t5/stm32-mcus/how-to-use-the-lwip-ethernet-middleware-on-the-stm32h5-series/ta-p/691100But ethernet is not being initialized. The HAL_ET...
Hi. I have a NUCLEO-H723ZG board. And my basic goal is to create from scratch non-rtos project with ethernet support. But after many attempts i cant get it respond to pings from PC. I tried flashing udp echo sample and it works, so hardware isnt faul...
Hi,I'm working on firmware upgrade functionality for an STM32G491 series MCU. In our system, the MCU communicates with a processor over I2C, where the processor acts as the master and the MCU as the slave. Currently, we're using I2C1 on the MCU for t...
Hi,I have an STM32F7 design with SD card connected via SDIO interface.In many posts I read that SD cards have to be initialized with a 1 bit wide bus and a clock of 400 kHz. Switching the bus width from 1 to 4 bit using the command HAL_SD_ConfigWideB...
I'm using STM32CubeMX to generate initialization code for all my hardware. I initially tried USART1 TX with GPDMA1 Channel 0 - all data was transmitted over TX except neither the GPDMA1_Channel0_IRQHandler() nor the USART1_IRQHandler() didn't trigger...
Presently we are using STM32F767ZI for our ongoing projects. Our application demands high speed data transfer rate through ethernet. We are taking the help of UDP for transfer of real time audio data between 2 STM32F767ZI Nucleo Boards. Further we ne...
