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...
Hello,I have problem statement, in which I have to re-Initialize lptimer for different timer value, as per current scenario, I haveClock: 32Khz (LSI)Divisor = 128Period: Any time as per dynamic input. So I want information about how I can safely rese...
I am using the OCTSPI1 of STM32L4Q5CGTX to set HYPERRAM to memory-mapped mode.Memory can be read and written correctly.When I use STM32CubeIDE to check the HYPERBUS signals with an oscilloscope while the CPU is stopped with a break during program exe...
Hi, I was trying to implement timer interrupt on an ST32F407 Discovery board. The ST-Link on my board has been broken so I used an external ST-Link dongle and I have it connected by following this post:https://electronics.stackexchange.com/questions/...
I want to measure ADC on multiple pins. I don't need DMA, just measure PA0 then measure PA2. Measuring PA0 works, but when I switch the channel to 2 it still measures from PA0:In my main loop I do this: // Configure channel ADC_ChannelConfTypeDef s...
