I've designed my first custom board using the STM32F412 microcontroller. I'm currently facing issues trying to flash the firmware via USB and USART boot modes, but nothing seems to be working.Here’s a summary of what I’ve tried and observed:Boot0 is ...
Hi,is the STM32F103RET5 can be damage, when boot0 short to PB7 or PB8 by oscilloscope probe for short time?After I fix the board the STM32F103RET5 work ok.is boot0 in float is 3.3v?is 32kHz input short to input 8MHz can cause damage to STM32F103RET5?...
Good morning,I would like to request support regarding the programming and debugging of the STM32U031C8U6 microcontroller. It is mounted on a custom-designed board, and I am experiencing issues connecting to the microcontroller via SWD for programmin...
Hello,My agenda is to work with ADC1 with STOP2 mode.Using LPTIMER1 to wakeup system, from STOP2 mode and once wakeup then reinit adc, calibrate and start adc interrupt. but still I can see adc interrupt not called.void handleConversion() { ReInit_...
Hello.I work on a project (the microcontroller is STM32H733VGT6) where VBAT mode is used. When the main power supply is switched off a supercapacitor supplies power to the backup domain (RTC, backup memory). This works correctly but the behavior of t...
Hello,In our project we are using STM32N6.We want to use UCPD1_CC1 and UCPD1_CC2 pins as a GPIO but CubeIDE does not generate code for these pins as GPIO.How we can use these pins as GPIO?Best regrads,Egemen Aksoy
Hi everyone,I'm developing a USB OTG Highspeed using STM32F756ZG with USB3340 USB PHY.Currently I'm using two OUT endpoint (EP1 and EP2), the host PC send each request (EP1 --> EP2 --> EP1 --> EP2 and so on). I got a problem when I try to send a requ...
Hello !I have to admit that I am stumped on this problem, I've been trying to make it work for the past few days.My issue is with an STM32F301K8T6 (LQFP32) and its ADCs : I have two reflective optical sensors (ITR8307) that are connected to ADC_CHANN...
Hi, I'm in the process to design a board and an application based on the STM32U5G9ZJT6Q. I plan to disable the SMPS power supply. So I'll put the following pins to ground:- VSSSMPS- VDDSMPS- VLXSMPSI plan to utilize several GPIOs, about 90+. At page ...
Hi! I am working on a project in which I'd like to use an stm32U0 MCU. It'll be my first time with one of these, and I'm choosing it because my design includes a battery (+charger & fuel gauge), so I'm interested in learning about low-power things. I...
