Hello,I’m using the STM32H503CBT6 microcontroller in my project. At this stage, the firmware simply toggles a single LED. I’m using STM32CubeMX (code configurator) and compiling with STM32CubeIDE. The system is configured to run at 250 MHz using a 16...
I'm working on a project which uses DMA to pull data from an external chip controlled by the FMC into a buffer in AXI SRAM, and am seeing a much lower throughput than expected. It looks like the FMC is idle for long periods of time, and I'm looking f...
Hello,I implement RS-485 on STM32G491. I receive with ReceiveToIdle_DMA and I also transmit with DMA. I need to know if currently something is being received because that means I cannot send data now because RS485 is half-duplex. As far as I know I c...
Hello All, I am developing a design based on STM32N647A0 and have limitation on the number of pins to accommodate 16 data lines. The PSRAM used in STM32N6DK board is APS256XXN-OBR-BG and is based on 16 data lines. So, can i use APS6408L-3OBM-BA, PSRA...
Hi all, Is there a Modbus tcp/ip Server (Slave) and client (Master) examples for STM32 Nucleo F429ZI board or any other similar boards? Thanks,
Recently I have encountered a strange issue I cannot really explain...I have a firmware that manages serial UART communication with a callback that has a state machine with 3 states.In the first state, UART is set to perpetually expect 1 byte of data...
Hello,Trying to achieve wakeup system at every 60 sec or more using LPTIMER1 in STOP2 mode.Observation:1. STOP2 = enable and LPTIMER = 60 sec --> Wakeup not work2. STOP2 = disable and LPTIMER = 60 sec --> Wakeup work3. STOP2 = enable and LPTIMER = 2 ...
can anybody answer please, if i costmised board based on bg431besc1 board it needed to upload boot loader file in stm32g431 controller to run in stm32ide code ?
I am using IAR + STLINK-V3PWR for my project. If I stop and resume program execution, on the STM32L433 MCU the TRACE_IOEN bit is activated and SWO intercepts pin PB3 . How to disable SWO ?
We are currently using the STM32H723VGT6 MCU (1MB Flash) in our application.We would like to clarify whether this MCU supports execute-in-place (XIP) from Quad-SPI flash or if Octal-SPI is required for XIP functionality.In the future, if our applicat...
