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...
STM32H745 parallel transmission
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...
Changing sample rate on streaming with H753 board
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...

Resolved! External QSPI with STM32H753
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...
Resolved! Peripheral Clock Drift Tolerance on STM32F303ZE (USART, USB, SPI, I2C, ADC, CAN)
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...
Resolved! System Clock stimluation error
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...
