STM32H735 using the RMII interface to the LAN8742 PHY chip. Right out of the eval board schematic, and it seems to work. USB also implemented in the usual way....and it works, until we turn on the LAN support in X-CUBE-AZRTOS-H7. Then the middleware ...
Hello I am using an STM32G491RcT6 processor, when I connect it with ST-link to CubeProgrammer the Write Protection section of the option bytes does not appear, if I connect an STM32G491ReT6 processor it does, Document RM0440 does not seem to me to re...
Hello there!I would like to ask for help from those who know this MCU family about the system memory bootloader. As specified in the AN2606 Rev64 document, section 41.2, after the System Reset the microcontroller checks the value of the nDBANK and nD...
Hi,I am working on STM32F302K8 and would like to use it's CAN Bus to communicate between devices both as master and slave It is my first time using STM32CubeIDE and the HAL library and implementing CAN Bus on my work. I did use some samples scattered...
Hello,Nobody at STM seems willing to answer my questions to the NUCLEO-H7S3L8 board. I've two of those boards and spend much time with them, but nothing will work. None of the examples from STM32CubeIDE can produce any results with those boards.I wro...
I have a bit of code as follows:str r3, [r0, #68]ldr r3, [r0, #68]where [r0, #68] is TIM20.BDTR on a STM32G474. I would expect that the LDR would output the same data that was just stored, however it seems that out outputs the previous data. I al...
MPU:STM32H755XI6Connection with PC:USART1RTOS:ZephyrIn order to install Zephyr into STM32H755XIH6, if you build and burn images for M4 and M7, the M4 side will start but the M7 side will not.The content is LED flashing of PG10 (A9pin). Are there any ...
Previous post: https://community.st.com/t5/stm32-mcus-embedded-software/dma-on-stm32l011f4/td-p/742092 I am working with code on the STM32L011 that uses DMA to read data from USART2. I received excellent help on this forum before and I'm hoping fo...
Good morning, I am trying to print a string on STM32F401RBT6 using vs code and Cmake, but I keep getting an issue, when I use '\n' the UART doesn't print nothing beyond the '\n', can somebody help me with this issue, please? printf("Hello\n World");
Hi, The reference manual says - "In differential input mode, the analog voltage to be converted for channel “i” is the differencebetween the external voltage VINP[i] (positive input) and VINN[i] (negative input". "In single-ended input mode...
