I am giving it what I think is a reasonable waveform with < 2ns monotonic edges. It all works but I would like to make sure.I posted waveforms herehttps://www.eevblog.com/forum/microcontrollers/32f4-is-there-a-spec-on-the-50mhz-clock-from-the-eth-phy...
I have 4 x STM32F373CCT6 on a custom board connected to a USB hub, all of which are clocked from a 3v3 24MHz oscillator ( rather than putting down 5 crystals and all the caps ). I have the 1k5 resistor pull up on the D+ line. when the board is power...
Hi everyone, We are developing safety device which need to go in a fail safe mode in any kind of failure to achieve SIL2 or SIL3 level of safety. And we want achieve UL certification.And we are using STM32G0B1CBTx MCU. And for writing code I am refer...
There used to be a flowchart showing all the ways of programming the STM32H7 series through various ports including SPI, UART, etc, showing the order they are checked. But I can't seem to find it anymore. Can anybody point me at it please ?
I want to use TLS on lwip using modbus tcp applications. But when I choose the mbedtls on CubeMx, I couldnt select lwip. If I use the Freertos, than I can selecect both of them. But I dont want to use FreeRTOS how can I use lwip-tls together ? In the...
My setup is STM32H745I-DISCO board with VBAT connected to a 3V2 battery (solder bridge removed).Here's my clock configuration:When I set up the date and time with my UI and then watch how it ticks in real time - nothing happens. I mean - it holds tim...
Anyone know STM32H7 (STM32H743) support usb gadget ethernet?I read somewhere STM32F7 does, but not sure about STM32H7Many thanks.
the goal of my project is to modify the ST lib to have composite HID and I would like to have some leads to know what I should modify, for example I know that I have to open an endpoint and also create an supplementary interface for the host but ther...
I am trying to build a sample application that initializes a NOR Flash SPI chip and then exposes it over USB to a Windows computer as a removable mass storage device. I am using FileX and USBX. Host is STM32F429 (Nucleo 144 board) and Nor flash is ...
