I’ve created a SPI peripheral as a slave in transmit-only mode. It operates in circular mode DMA and generates a complete callback every 20 milliseconds. Upon receiving the complete callback, I want to modify the source address of the DMA request.Cur...
Hello everyone,I’m trying to activate the USB module present on my custom board equipped with the STM32G0B1ME microcontroller. Currently, I would like to see data transfer from a PC serial terminal to the microcontroller. Unfortunately, this is not ...
Hello,I'm looking for an STM32 evaluation board that supports UART communication at 20 Mbps. Ideally, having two separate UART ports would be nice, but one would also work.I've read that the STM32H7 family supports higher UART speeds, but it seems th...
Hello STM32 community,I am currently working on an STM32 project where I need to manage two RTC alarms: Alarm A for periodic wake-ups and Alarm B for switching modes after a specific timeout. The system enters standby mode and wakes up multiple times...
Hello Having real issues with the I2C DMA HAL code ???Is it buggy.... very likely from what i'm reading on the web or is there something I am not understanding ??I'm simply trying to read data back from a i2c flow sensor with minimal interruption to ...
I m working with STM32 MCU from last 3 years i made many boards for STM MCU but i never face the problem which I'm facing now. In past i made boards for lower pin packages ( up to LQFP 64 ) mostly they have single power input pins this time i made a...
I have quite a complicated case, where a interrupt is beeing executed, allthough it has been disabled, and its flag beeing cleared. At the same time interrupts are disabled, and i put a few nops in between just to rule out any delay related issues. T...
Hello all, We are evaluate STM32H745 for one of our new products. Dual core feature of STM32H745 is something we would like to use. As a part of initial process, I was trying to debug both M4 and M7 cores simultaneusly.Following AN5286, I was able t...
We are trying to develop a device that uses SPI communication (Transmit Only Slave).Are there any sample programs for SPI communication (Transmit Only Slave)?What should be the trigger for calling HAL_SPI_TransmitReceive? Master's CS?
Hello,I would like to use 2x AD7606 for simultaneous sampling of 8 channels, the samples shall be sent to the STM32H753 CPU that will perform some DSP calculations. This system is intended for 3-phase grid monitoring system.I preferred the SPI mode r...
