I am using the STM32411CC MCU for reading a signal from a GPIO IDR, process it, and write it to a GPIO ODR. An interrupt routine is a suitable method for signal processing on demand. Question: how can the host computer create an interrupt during runt...
I've recently put together a new design and ST-Link doesn't seem to detect the STM32L486 on the board using the STM32CubeProgrammerThe part used is the 144 LQFP version, but I've double checked the pins and connections for the SWD port. I'm supplying...
Hi I’m looking for a low cost STM32 board that I can use to control a mosfet, take various digital/serial inputs and be controlled by a touch screen. If anyone could recommend a board in the $30-40 range and lots of io, similar to arduino mega if pos...
I'm working with STM Nucleo-L476. I want to mount the IC STM32L476RGT6U on my PCB. I got the footprint successfully; however, I'm unable to find the peripheral connection of the particular IC. I got the pin diagram clearly and know exactly where my s...
On the STM32G431x6/x8/xB UFQFPN48 I've been assuming that BOOT0 pin PB8 was a weak pull-up during reset, but in trying to track this I think it has no pull-ups/ pull-downs. Is this the case?
There were several issues so I am not certain which is the real issue.I am using STM32CubeIDE version 1.1.0Note I believe ST needs to consider more carefully how to install things and give direction when something seems wrong in installation. I belie...
I ask because I need to test the analogue part of a (custom) board which is powered from 12V, but also generates a 3.3V rail from that. I'd prefer to leave the ST-LINK connected if at all possible.
I am designing a custom PCB using STM32F722RET6. How to connect the VREF+ pin(13) on the SMT32F722RET6?.As per the hardware development manual, it says"The VREF+ pin can be connected to the VDDA external power supply"and then, "VDDA=VDD and VSSA=VSS...
Hi ST community,I'm working with NUCLEO L432KC and in my application I need to use I2C1 port. Using STM32CubeMX to generate the project, I could see that when I enable the I2C1 port, Automatically the CubeMX allocate the PA9 and P10 pins. For my appl...
