Hello,We observe issues with a set of stm32F407ZETx.The application stalls / hangs somewhere while calling MX_USB_DEVICE_Init(). We are using the USB in CDC class. The board is powered via a USB cable, and the issue is not observed when using a good-...
I have a problem in sending udp multicast frame via wifi (with the MXCHIP embedded on the card). The problem occurs when there are chained buffers in play. These buffers come from the lwip lib when Pbuf is allocated with the PBUF_REF option in the pb...
Hi, I have STM32F413VHT6 board and trying to use FATFS and SDIO card slot, but f_mount returns FR_NOT_READY. i worked in 1 bit mode is working perfectly but SDIO in 4 bit mode f_mount return FR_NOT_READY.i am using below code for both 1 bit and 4 bi...
HI: Due to special needs, the system clock frequency needs to be changed during work, switching between 72M and 48M. Using STM32F103, the USB CDC Virtual COM Port cannot function properly after switching the clock.Using STM32F407 to dynamically chang...
I paid someone and she came up with a solution using STM32F103 and claims that it works for wav files using PWM and low pass filter with a digital attenuator. It didn't, and 1 year on I am still looking for the right MCU and the right solutionUM1642...
Hello,I'm using SDMMC to save ADC DMA data to an SD card on Nucleo H723ZG. I made some tests and got distorted results. Then I realized a problem, sampling speed is too slow when I use fatfs writing commands. What might be the problem?I use a 64K buf...
HI, I m trying to send a 16 bit word using SPI HAL to a SPI external interface driver. SPI is configured as:-Transmission master-16bit data TX-MSB first.This driver requires first address of the register and then the content to be received. I created...
