Resolved! Question about DMA usage from STM32F0x1 reference manual
Hi friends from community. I have a question about the paragraph about DMA section from STM32F0x1 reference manual page 200, as showed below:I don't know how to understand the red highlight part of above picture,why there says <these ‘memory’ registe...
Resolved! Using CTS and RTS signals connected to the mcu's NBLx pins
The schemes of a production circuit are given to me from another designer for being analyised. PCB board is a STM32F103VC based circuit.When I was looking at the bootloader circuitry scheme I saw how RS232 bus seems to be connected to the UART1 micro...
Resolved! Read/write latency while dynamically adjusting counter phase
I want to be able to continuously adjust the phase of a timer output via input capture on another signal. I do not want the timer to be automatically triggered or reset by the external signal because I want some processing in the loop to determine ho...
STM32H7 Camera Buffer YUV TVP5150 JPEG
HelloLet's assume I have a TVP5150 device connected to a STM32H7 MCU. The TVP5150 transmits PAL frames as YUV. This means 2 bytes per pixel.This results in 720x576 * 2 = 829.440KB per frame. In reality, there is pretty sure the need for double buffer...

Hey. I'm trying to create a program that receives 4 bytes long strings from my pc and transfer them through an spi connection to a peripheral device, throught a usb connection.I've set my stm32 nucleo board up as a usb device and generated the requir...
STM32G0 and UART single-wire, half-duplex comm. fails after software reset
I am using the NUCLEO-G071RB, STM32CubeIDE (v1.14.0), and the HAL library STM32Cube_FW_G0_V1.6.2 for prototyping firmware that should communicate with an external device using UART single-wire, half-duplex communication.The expected startup response ...
Resolved! (Urgent)Inquiries about improving the response speed of device Ethernet communication
I am developing a device using the nucleo-f429zit6 evaluation board as a reference. This device has an Ethernet communication function, and the Ethernet communication function was tested by directly connecting this device to the server using a cross-...
