Hi all, I am using STM32U575ZIT nucleo board. My goal is to write ODR register of GPIOD by using GPDMA transfer, using TIM2 to trigger the memory-to-peripheral transfer. In this "test" script, I use a 2-elements source array to force ODR all high a...
Hi,I would like to ask a question about DCMI. I am working on one task with STM32H743VIT6 MCU. My task is take an image from MT9M114 sensor using DCMI.MT9M114 is a camera sensor to capture images. Interfacing MT9M114 sensor through DCMI with STM32H74...
Hello,we use the STM32G474 with a single supply voltage of 3V3 at the VDD Pins.At the moment we investigate defective microcontrollers. The Microcontrollers are defective after several hours with the 3V3 VDD voltage supplied. The defective is an incr...
I have a custom board with STM32H747IGT6 MCU, which communicates with a S25HL512TFAMHI010 flash memory chip over QSPI. I have made several iterations of this board, and the QSPI communication has always been fine.However, on the most recent iteration...
Hi Guys,I need some help / input:I am trying to get the communication running between my Nucleo H7A3 and a Shield with a ISSI QuadSPI RAM in a SOP-8 Package running.Scenario:I am debugging with my Scope, I have a digital Probe on all 6 lines (CSn, Cl...
Hi,I am learning and exploring the STM32F756VGH6. My goal is to setup a simple UART and send some data to the PC using USB-UART serial converter and puTTy terminal on PC. I am using register based coding approach as it makes the code more efficient....
Hello everyone,I have carried out some experiments on five different STM32 microcontroller devices (STM32F103) measuring the values of the pull-up and pull-down resistances integrated in the GPIO. I have created a voltage divider between VDD and grou...
I am using STM32L562 microcontroller. I am unable to interface it with sdcard using sdmmc and fatfsmy sd cards are- 8gb (formatted in fat32)[old], 32gb(unused)[new]. In both sd cards I am getting the same problem- disk error occurred (FR_DISK_ERR) it...
Hello everyone,I am currently developing a GUI for the STM32F469I Discovery Board using the TouchGFX IDE. The GUI works perfectly when updated through the TouchGFX IDE.However, when I attempt to update the same project using STM32CubeIDE, I encounter...
Hi all,we are developing a board based on STM32F429 chip.In particular I'm developing a composite USB device on USB OTG port, showing a custom device + a CDC device [ep 0x85, 0x06, 0x83] using USB_Device_Library code.Windows correctly shows 3 items: ...
