Dear STM Community and Experts,we are trying to implement a dual-port USB-C design using STM parts with the following requirements:Port 1: USB-C Power Delivery (PD) Sink, 100W, no dataPort 2: USB-C non-PD Source 5V 2A max., USB 3.1 Gen 1 Data, Displa...
Hi, I have Interface (type MASTER) 10-bit + CLK, FCLK=~9MHzCan I use DCMI to read 10-bit without VSYNC and HSYNC?Or some other method? The usual assembler software method "ldr r1, [port, #....]" is too slow and despite many attempts it has not been p...
Hello, I am implementing audio streaming with H753 board. My goal is like below. 1. Input : USB connected PC, which can be selected one of 48kHz and 44.1kHz sample rate on connecting state. Others are fixed as 16 bit / 2 slot ( stereo ) 2. Ou...
Hello All, I am doing this post after trying everything I can to solve my Issue. I have a STM32F411 Blackpill connected on an Apple II Bus Slot.The Apple II has a clock (Phi0) close to 1 Mhz. Phi0 is connected to Pin A2 where I have setup a Falling &...
Hi all,I'm building a discharger using my STM F446RE, such that it's RTC registers are used to store data that'll be loaded to set parameters in my code every time the discharger is plugged into the power. Just to clarify - I'm NOT using the RTC as a...
Hello, we are facing some problem entering DFU mode from application code on our custom boards equipped with STM32H7B3 with bootloader release 0x92. On contrary, everything works fine with same board equipped with STM32H7B3 bootloader release 0x91. ...
Hi, I am planning to use the external serial QSPI flash interface with STM32H753. Flash part number is MT25QL256ABA1EW7-0SIT or IS25LP064D-JKLE-TR. Operating voltage 3.3V at frequency of 80MHz DDR. Can you please let me know will there be any concern...
Hi ST community,I'm using the STM32F303ZE in a design and need to ensure that the clocks for various peripherals stay within acceptable tolerances (in ppm or %) — especially across the full temperature range (–40°C to +105°C). I plan to use an extern...
I am using the startup file in Keil. However, when I run the simulation in the debugger, my system clock (SYSCLK) is not 72 MHz, even though I have confirmed that HSE_VALUE is set to 8 MHz.Can someone help me figure out why the SYSCLK is incorrect du...
Does the STM32U5G9ZJT6Q SoC not support SDMMC2?
