Hello everyone. Question about synchronous launch of three timers.Given:- CPU F0 or F4 or G4 (of course F103 is possible - I just don't like it, personal dislike);- three timers, each with its own operating frequency, Timers work via DMA, each with i...
Hello,I am trying to implment MODBUS Slave RTU with STM32F030C8T6. I havce used RS485 for physical layer for communication.As per MODBUS protocol, a stream of 8 bit data will be sent from Master. As a first step slave must capture all the data in an...
Hi!I have a doubt as to when to choose FMC and when XSPI in regards to working with screen GUI with stm32h7s7. In few youtube tutorials, they are using FMC to load data to the screen but in the development board ".ioc" for the same the XPI1 and XPI2 ...
Hi,I would like to implement a Modbus TCP server based on the library cubeMX and LWIP with the ability of multiple client connections.With only one client, it works perfectly well. With 2 clients, they can connect simultaneously but as soon as both s...
Hello everyone,I am kind of new to STM chips, i have a problem regarding programming the chip. I don't use any board, only chip on the SMD to DIP board. But when i want to program it using st-link, STM32cube can identify the programmer but not the ch...
I am using STM32H747-DISCO board for development, and I try to access for MDIOs connectivity of the STM32H747, I found a document describe about MDIO:STM32H7-Peripheral-Management data Input Output slave interface (MDIOS)From the document it describe...
Hi, I have a strange situation I can't figure out. I'm new at DMA so I just follow directions as best I can without a full understanding. Right now, my setup is more or less working for a few months. But today I encountered a problem. I am using UCP...
In STM32F405xx STM32F407xx datasheet On page 19/203, there are typos in APB2 and APB1 frequencies.
Hello all,We are currently using the STM32G0B1RE in our design, where both HSE and LSE external oscillators are used. The PLL is configured to multiply the 8 MHz input to 64 MHz. All clock configurations are performed via STM32CubeIDE and HAL, and th...
