Hi everyone,I'm working on an STM32G070CBTx, and I need to execute two different functions depending on the GPIO mode of pin PA12.Specifically:If PA12 is configured as input (GPIO_MODE_INPUT), I want to run function1()If PA12 is configured as output ...
I have an STM32F401 nucleo board and it used to work fine but now after a minute of connecting it with usb, the LD1 suddenly dims to very low light like pin on float. Before that it works fine, I can program it, debug it.
Hello, I am developing a electronic card that is supposed to be used in an automated test bench. I'm using an STM32G474 to control the card. I have already created one iteration of the card but I realised I made a mistake.I wanted to use the bootload...
Hello everyone,I’ve integrated USBX configured as a Mass Storage Class (MSC) device into my project, which uses the STM32H743BITx MCU. The project compiles successfully, and the system detects when a USB device is connected. However, enumeration fail...
The FDCAN module generates timestamps for sent and received messages, and you can configure it to use TIM3 as the source. Unfortunately, the documentation is rather thin, so I am left with a few questions:Do TIM3 and FDCAN need to run from the same c...
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 ...
