Hi,I'm using an STM32H750XBH6 with an ISSI IS42S32400J-6BL, but the read/write operations keep failing.I’ve tried setting the CLK to 166 MHz / 120 MHz / 100 MHz / 50 MHz, but it still fails.When measuring with an oscilloscope, I found that the FMC_Dx...
Hello everyone.How do I update the firmware via VCP on STM32F407VET6? Is it possible to do so? If so, what needs to be changed and added? Do I have to recreate the bootloader?I don't know where to start here.Thank you :)
I have a question about PVD.I have this main.c file. My interrupt function void TM_PVD_Handler(uint8_t status) won't execute when the power goes off. Why? In this case, I'm sending a message to the UART to see if my computer recieves the message befo...
Heyho,management asked me about a project involving 1 or 2 audio input channels at 32-bit / 200 kHz and - here's my knowledge almost zero - some "heavy & intense" DSP / FFT algorithms for real-time signal evaluation.We're already using the H723 .. H...
Please i need help.The datasheet, says the VDDA voltage level must be always greater or equal to the VDD voltage leveland must be provided first.My qustion is: will my circuit work, if I tie the VDDA and VDD together, to be powered by the same LDO D...
Hello ST Community,I'm working on implementing USB Audio Class 2.0 with both speaker and microphone functionality on STM32WBA65 using USBX middleware.Request for Example: Are there any complete working examples of USBX Audio Class 2.0 with microphone...

Hi everyone,I’m trying to generate a square wave using TIM5 Output Compare (OC) on an STM32H7 board. I configured TIM5_CH1 to output on PA0, both in CubeMX and manually in HAL_TIM_MspPostInit(). Here is a snippet of my GPIO init: GPIO_InitStruct.Pin ...
Hi everybody,I've two cards with a STM32F446 on them.My first one works very well, the µc starts a each time.On the second card, the µc starts sometimes (I have a LED on my card that blinks at start).I've checked Vcap (2.2µF), the 3V3 rising (1ms), b...
Hi everyoneWe have designed a custom board around the STM32L081CZ and produced 3 prototypes. On the first board I started testing and debugging using STM32CubeIDE on Windows. This worked fine but only with ST-Link, not with J-Link.After testing (and ...
