Hello, I have a really strange problem with our STMF407 custom board that connects to a full-size SD Card socket using SDIO. The MCU uses HSE at 8MHz and SDIO configuration as a 4-bit wide bus and div factor = 0. All the other values are SDIO de...
Hi, We had an LCD problem with a recently bought board STM32F769I-DISCO, revision MB1166-A09. Now it's resolved by recompilation with macro "USE_STM32F769I_DISCO_REVB03" entered in project options. My question now is how can I make it universal, with...
ST states that the STM32F730R8T6 has Quad SPI, but it is missing QUADSPI_BK1_IO2 on the pinout?!?!
For learning (and suffering) purposes I am trying to write my own USB Driver in device mode. Right now I am just trying to successfully enumerate the device. So far I am able to read SETUP packets but when writing to EP0 (IN transfer) the requests se...
Dear Community,for my application I use the STM32H723VGTx where I'm using the OSPI interface as a SPI and QSPI to control a external sensor (MCU SPI master, sensor SPI slave). Now I face some issues with this communication interface, for debugging re...
Hi, I have a custom board using STM32G431CBU6. I am using `dfu-util` to upload firmware and option bytes. I don't have any problem reading/writing flash area with DFU, and I can read the Option Bytes area with DFU, but when I try to upload a valid op...
I am trying to dump stack trace from hard fault handler using usb, but the usb not working in hardfault handler.Any one please help me to know why usb not working in hard fault handler, if there is a way to use usb in hard fault handler
Hello Community,I am programming the STM32L562E-DK discovery board and working with the Standby low-power mode. In the data sheet there are 3 standby variations explained:Standby with Full SRAM2 data retentionStandby with 4kB SRAM2 data retentionStan...
Hi,I am trying to create to PWM outputs with a variable phase shift between them. They are of fixed frequency, 50% duty and exactly the same shape but with variable phase shift. I need to dynamically change the phase shift between them as a control p...
Hello,I have some strange behavior with a circuit. My understanding is that the GPIO should be configured as an input at power up, however, I am seeing a brief flash on an LED during power up and Power down (images attached showing circuit and the 3...
