In our project I use STM32H573VIT6 LDO uC. We have a problem with the PB14 pin. We use 3 pins for LED control (PB10, PB13 and PB14, see photo). The problem with the PB14 is that the LED lights up dimly without code initialization. If PB14 is initiali...
HI,I am working on a board using STM32H573V and have a working solution with UCPD detecting an inserted memory stick and running the MSC class. In an other part of the software I am using PC9 as an GPIO push-pull, low speed output and as soon as I se...
I designed a board that uses a STM32H750 with a USB3300-EZK that has stopped communicating over USB. It's been having intermittent issues for the last day or so (sometimes I'd need to power cycle the board before it would show up, but then it would w...
Hi,we are trying to get a 800x800 display to work with the STM32U5G9VJT6Q, using either RGB888 or RGB565 in Video Mode (Burst).According to what we read it is definitely possible. Did we miss something?Could someone please confirm that is definitely ...
Hi everyone, I am facing an issue with CAN communication on STM32F446ZCT6, where the CAN controller frequently enters the Bus-Off state. Hardware Details MCU: STM32F446ZCT6 CAN Transceiver: (TJA1042T) I am working with CAN communication on STM32F4...
Hello.How can we enable brown out for this processor and the brown out voltage?Thank you.
Im trying to run SYSCLK from LSI on a STM32C011. But it appears as if the MCU is not running. I cant see anything in the datasheet that says the clock cant be used and it can be routed fine in the clock configurator. Am I missing something in the dat...
Hey all, I have been debugging a nasty issue that I have been having over the last couple of days. I am using the STM32n657I0 MCU. The issue that I observed were random crashes in my code. Luckily the problem was well reproducible. What I observed wa...
I'd like to use the DTCM ram in my code; how can I do ? Thank you
Hi,The external nor flash AT25XE321D is 32Mbits, support quad IO/XIP spi operation, max. 133MHz Freq. Std. JEDEC/SFDP. It is connected to STM32H7R7Z8J6 with with XSPI1 port-1 interface.I am using MX v6.116.1 to setup project for my board. By IDE v2.0...
