Ask questions, find answers, and share insights on STM32 products and their technical features.
I am using the H743 microcontroller and am looking for some more information about the GPIO EXTI controller.Specifically, how long does a signal need to be held on a GPIO in order for the EXTI to detect a rising or falling edge?I notice in the timer ...
Hello,I’m working on a telephone‑line–powered device based on the STM32L072VBT6 and I need to push the MCU’s Run‑mode current down to ≤ 1.2 mA (ideally lower) while on‑hook. So far I’ve managed to get down to 1.6–1.7 mA by applying the following:CPU ...
Hi,I am using the STM32F407VET6 chip to simulate the SENT protocol. I have encountered some issues and would appreciate it if professionals in the forum could provide some answers.1.Since the SENT protocol signal needs to change the output waveform b...
Heyho,a few questions to those who already used the PTP offload function (not via IP / UDP, but PTP directly over ethernet, MAC packet type 0x88F7), which can auto-generate SYNC and DelayRequest messages:1) As this feature does not auto-generate Foll...
Hello,I'm working with the STM32H723 and need to interface with an external ADC that provides a DRDY (PG2 pin) signal. I'd like to initiate an SPI transfer via DMA whenever the DRDY pin goes low. The ADC is connected to SPI6, and I understand that o...
I bought the STM32H750B Discovery and wanted to program a first example "LTDC Paint" on the demo to start.I am using the STM32Cube IDE version 1.9 (default installation, no changes made).Procedure:- File -> New -> STM32 Project -> Examples -> select ...
I have the following clock tree for STM32L471I am using TIM2 as trigger for DAC, ADC1, and ADC2 at 2.4MHz. Clock frequency of TIM2 is 48MHz with a counter value of 19 and prescaler = 0.With oscilloscope, I confirmed that the DAC is generating the sig...
I am designing a system with an STM32 and an FPGA(Xilinx 7 series).STM32 is in charge of the user interface and the FPGA is in charge of driving the LCD to show images.Information needs to be exchanged between the STM32 and the FPGA. (STM32 send a co...
Hello everyone,I'm currently working on a FOTA (Firmware Over-The-Air) system for my STM32-based project, and I’d love to get your insights or validation from the community regarding the architecture I'm considering.My Goal:To ensure safe firmware up...
Hi STM Team, We are planning to use STM32G491 MCU in our application. As per datasheet, it is mentioned that STM32G491 MCU will support USB PD 3.0. We have come across the below STM document where it is mentioned that "STM32 UCPD MCUs are compliant ...
