Hello!Prehistory:USB DFU works flawlessly on another my design which is based on the STM32H743ZGT6.When it is powered on with BOOT0=1, I measure 3.3V on the USB_DP processor pin with a USB cable disconnected from the board.Problem:There is a USB DFU ...
Hello everyone.I am currently considering using the STM32H735 AD converter.As shown in the figure, I have inserted a Schottky barrier diode and a 1kΩ resistor just before the ADC terminal pin for overvoltage protection.I was curious about the input i...
Good day everyone. I am working on the STM32H7 MCU and using the HAL library for controlling an SPI in DMA mode that has to exchange data with an external device in real-time. I'm working at the maximum possible CPU frequency and using the -O2 optimi...
I'm trying to send a Audio data from MEMS microphone to Device through USB. I had defined a configured a descriptors accordingly. But I'm facing Error message that is *!*ERROR: No open pipes!.[Port1] : USB Composite DeviceIs Port User Connectable: ye...
Hello I am validating the ADC DMA Timer using stm32u5I am doing when ADC and DMA are working fine but timer is not working getting into the error handler what I am doing is I want start ADC and DMA when timer trigger but the timer is following error...
I'm working on a custom PCB with an STM32H750VB and the ST-link is unable to find the target in both CubeProgrammer and St-link Utility via SWD, below are screenshots of some of the error messages I received and our microcontroller schematic. I've pr...
I need IBIS model for part STM32F303RET6.Thanks in advance.
I just updated my STM32IDE to support the STM32H5 series parts and I noticed in my project that LWIP is no longer a middleware option. Is it not supported on this family?
Hello everyone,I have a question about 5V tolerant I/O in analog mode. When I look Figure 20. Basic structure of a 5-Volt tolerant I/O port bit in RM0377, i don't see the analog arrow as in figure 19. Is it an error on figure or 5V tolerant I/O doesn...
Hello,I am in the process of selecting a microcontroller for my application and would like some guidance on which microcontroller would be best suited for my project. My project has the following known specifications/interfaces:- x3 UART ports up to ...
