Hi all,I am using a mass-produced PCB board for a project, the chip model is STM32F429BIT6. The PA1 pin is used as ADC1-IN1 for access to the sensor.However, I found a strange phenomenon that after configuring the ADC, the initial reading of the pin ...
when creating new project, only 'Empty'.""This functionality works correctly in v1.18.""The issue appears after upgrading from 1.18 to 1.19, or when directly installing 1.19."
Hi, I'm trying to initialize SDADC of my STM32F373CCT6 chip based on the Standard Peripherial Library. The program can be compiled with no errors but doesn't work after I uploaded it to the chip. I used a LED program to test it and found that the ini...
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...
