    I need a Microcontroller with a sampling rate of 50kHz or faster, to connect multiple sensors for edge computing and stability characterization

    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...

    Using an SiP chip.

    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...

    stm32f103c8t6 st-link connected but failing to upload code

    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.

    Why the initial state of Bistable multivibrator using 555 timer is coming 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...

    How to interface CMOS image sensors with 32-bit Microcontrollers?

    I've been learning to program 32-bit ARM cortex-M controllers with an STM32 Nucleo (L476rg Nucleo). I've been playing with interfacing and controlling stepper motors so far. My next step is to move on to machine/computer vision and incorporate image sensing however upon some searching (hopefully...

    My HID doesn't output the correct values - STM32

    I'm making a force feedback wheel with an STM32F103. So I had to learn about HID. I made a very simple descriptor, to begin with. I'm supposed to see the buttons count in binary in the controller visualizer but they're random. Comparing the received value in USBlyser, when it's 0xA9, buttons 1...

    why should we work with STM(scanning tunneling microscopy) at low temperatures and in high vacuum

    Hello i would most importantly love to know the answer of why we should work with STM at low temperatures. I understand that we need to work with STM microscopy at high vacuum so that we can make the work function easy , since it is a metal to vacuum interface . but i don't know if that...

    SWD USB connection

    I will be building my own board STM32 for my projects, I've noticed people always put breakout sockets for SWD. My question is why? why not make it connected to the usb port for simpler debugging/uploading code

    First time interfacing MCU with external SDRAM

    (Links are component datasheets or application notes.) I have a project using the STM32H series MCU that requires external SDRAM for data storage. Due to the size, the PCB is going to cost near $1,000 to fab and so I'd like to make sure that the design is correct before sending it to the board...
