Brief: Want to use STM32L432 MCU and FUSB302B PD controller asking voltage higher then 5V. Question: Where am I set wrong of the PD controller? Is there anything else I need to consider when asking the PD source? Hi, I'm working on a project for digital auxliary power in card size. The...

I am working on a project within my company that involves a relay board used to control three different motors when an external 24V button is pressed. The existing setup works based on this principle. Now, I have been tasked with designing a new board that maintains the current logic while...

The arm.developer.com states that "At Reset, Cortex-M3 and Cortex-M4 processors always boot from a vector table at address zero". How is it possible that f.e. STM32F446 has the vector table located at 0x0800 0000 address? I know about VTOR, but it doesnt seem that it is used there to do that...

Hello guys, Im working on a project. I did a keyboard on my nextion screen. When Im pressing a character on the keyboard, nextion writing them on a text bar. Example: User pressing ----> 'A' , 'B' , 'C', ' ', 'D' , 'E' , 'F' (Like sending name, surname) Text Bar Looking -> ABC DEF (Like...

Perhaps someone had some experience with CO2 sensors? I am looking for a decently accurate and good quality C02 sensor for my my environment sensor board based on ESP32 microcontroller. My sensor board is being powered be DC power supply by default but it also has a small battery (800mAh) so it...

I am trying to get an external timer (TIM5) to toggle an LED at a certain time period. I am designing it to interrupt every 2 micro seconds. I use an oscilloscope to check whether it works as intended, but unfortunately it does not. The clock speed is 45Mhz And I calculate the period APBtimer...

I am playing around with an optical encoder built into a linear drive motor. There is a wire that is described as "Home indicator, TTL, Active high". I have connected it to PA4 on my Nucleo-F446RE (STM32), have set it to "GPIO_input" and have set the GPIO to "Pull down". I am trying to read...

Hi community, I'm Marco from Italy, I'm an electronic developer and I like automation in general. I would like to share my problem with community, to know what do you think about this. I'm developing an electronic board for general automation purposes, on this board there is a STM32F104 that...

I am using the LoRa Development board B-L072Z-LRWAN1 and it has got STM32L072CZ microcontroller . I want to write the Firmware Update over the Air (FUOTA) Application code to this board. Please share me the reference code links for the Bootloader code or send me the FUOTA application code for...

Hey I am new to STM32, I am using CMWX1ZZABZ_LoRa_Module. Can someone tell me if I can use LPUART1 and USART1 simultaneously? Are they Independent?

I'm working on a project where I have to connect multiple sensors to a microcontroller. We thought about using Arduino mega but the sampling rate (9600Hz) is too slow for what we want to achieve and the machine data we're trying to analyze. We need a Microcontroller with a sampling rate of 50kHz...

Hello everyone, i am currently designing a PCB for a school project and have some difficulties in it's implementation. I want to use an STM32 MCU and make a PCB for it, the MCU does not contain any wireless communication capability, so I need to add a WLAN module to it. I have chosen this chip...

Hey everyone...a basic issue How can i get hdmi output from stm32? Do they have hdmi output themselves? if not what should i do?

Hello, I have a question about STM32F407. I was wondering how to software trigger (not external trigger) a "one pulse" timer, using HAL library? Thanks for the help.

Hi. I am using STM32F407VGT6 this one and RadioLink SE100 GPS. I am trying to get $GNGGA data via USART and displaying it in putty terminal. I am able to get and print data. After 3-4 minutes gps sensor led is blinking but no data is printed on terminal. /* USER CODE BEGIN Header */ /**...

I made a project to implement it on LCD through both Arduino and STM32, but after I use Arduino, there is no response when I connect to STM32 to click, what is going on?

We designed a PCB with stm32f030c8t6. We soldered the PCB and tried to upload the code. Power has gone to the stm32f030c8t6 successfully but when we arranged a pin as a gpio output it wasn't high.

I want to make a circuit for triggering the STM32 microcontroller into the Bootloader mode. For normal operation of MCU using flash memory the BOOT0 pin should be low and for entering the bootloader mode the BOOT0 pin should be pulled high. Presently I am using Bistable multivibrator using 555...

LSM6DS33'ün HAL kitaplığına ihtiyacım var. Elinde olan veya bana yardım edebilecek biri var mı? Mod Translated. I need the HAL library of the LSM6DS33. Does anyone have it or can help me out? bertp, Please use only English text. :)
