Good morning community,I am using the STM32L496QGI6 for a certain application using the uart to send and receive messages, in this case it always gives me symbols even with the baudrate correctly configured, I have checked the clock configuration and...
Can anyone give a hint on where to look for proper documentation on CAN bus development? I see some primitive examples online, though there are a lot of moments that are not explained as they shouldFor example, CAN filtering and identificator masking...
Hello ST Community,I’m currently working on a routed circuit where I’m interfacing an STM32H735IGT6 microcontroller with an external NOR flash memory (MT25QL512ABB1EW9-0SIT). While most operations seem to work as expected, I’m encountering an issue w...
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...
