Resolved! First write to Flash using EEPROM Emulator fails.
I am adding EEPROM emulation using the x-cube-eeprom package. On program startup I am calling EE_Init and I have traced the code through the checks for the flash to be used being erased, which it is. However, when the first element is written, the fl...
Interrupt Mode HAL Delay
Hello I am newbie to embedded word. I am trying to learn interrupt for GPIO on NUCLEO-F091RC. I set the User Button as interrupt and LED should toggle as button is pressed. I copied the callback function ( HAL_GPIO_EXTI_Callback) in main.c . Under c...
AzureRTOS on STMH563
I am looking to use AzureRTOS on the STMH563 devices but it does not appear to exist for the STMH5 series. Is there a workaround for this? i.e. use the STM32L5 one?
The best method to transmit continuous data from the STM32 to a PC at high speed
I am currently using the STM32 to sample a waveform with an ADC, perform the FFT and transmit the data to a computer. 2 ADC's are used, and the buffer fills up every 1.26 ms. The result of 12 FFT bins is transmitted to the PC, which is around 1400 bi...
Resolved! Example for Azure RTOS USBX device video (UVC)
Hello everyoneDoes anyone have example code for Azure RTOS USBX device class video (UVC)?I was able to add Video to my USBX demo application on Nucleo H7A3There was sample code for CDC_ACM and MSC (mass storage), this worked fine. But for device clas...
How to make lwIP work on nucleo-stm32f756zg board?
I have a nucleo-stm32f756zg board. I can't make lwIP stack working, which I tested with ping. I have read the relevant documentation (e.g. rm0385, um1974). I have read the official stm32 tutorial for stm32H7 (https://community.st.com/s/article/How-to...
Resolved! bootloader, ethernet and managing dual memory banks for software updates (NOTE: The MCU belongs to STM32H7 family)
I try to build system that communicate via ethernet and also wants to update software in the same way. The question is what is the best way to handle this kind of system?for example :1) my own bootloader + flash program x 2 ,bootloader will manage it...
Resolved! Which port number for TCP ethernet communication?
I am using an stm32h23zg, FreeRTOS plus TCP stack to create a TCP client.I checked, I can bind the socket to many values (tried 1, 52 and 1000, all 3 worked) but I couldn't find any recommendation on which port to use.On computers it is usually recom...
Resolved! Problem implementing a simple bootloader on STM32H743
Hello, I am experiencing a problem implementing a simple bootloader similar to the one showed by ST on youtube. I decided to use 32K of flash for the loader, while the remaining flash is available for the application. Linker file of the bootloader:ME...
