embedded

I want to use an off-the-shelf LPWAN radio product -- which has mesh networking capability and features an embedded microcontroller -- to sample a 12V battery's voltage. I don't want to do it often, so I'll configure the radio's interface to do synchronized sleep routines to wake it up and...

Hi everyone! I’m currently conducting an academic research project on the potential role of 8-bit microcontrollers in lightweight AI applications. As we know, Artificial Intelligence has been evolving rapidly and increasingly demands more computational resources. While 8-bit microcontrollers...

Hi everyone, I'm working with a Silicon Labs BGM121 microcontroller using Simplicity Studio, and developing in C. Server: My BGM121-based device (referred to as "marker") that streams raw sensor data over BLE. Client: Either the Silicon Labs Si Connect app on a phone or a Raspberry Pi 5...

Consider a embedded system such as Electro Hydraulic Power Steering ECU mounted in a heavy duty commercial truck. When key switch is turned off, the ECU should executes very limited functionality in sleep. It is not suppose to log faults in sleep mode?

[EDITED BY MODERATOR MOVING THE FIGURES TO THE BOTTOM WHERE THEY SEEMED TO BELONG ACCORDING TO THE TEXT] Hello everyone, I’ve developed a board that allows levitating a magnet using a feedback control system. It’s powered by a 12V jack and controlled by a Teensy 4.1 microcontroller. Everything...

Hello everyone, I'm currently working on a Hybrid vehicle project called REEV (Range Extended Electric Vehicle) for a competition organized by SAE India. The VCU in our car is connected to critical components like the battery, motor, generator, and various sensors. I need to acquire data such...

Hello, Internet community! This is my first time posting in a forum, and I need some advice for a project I'm working on. I'm designing two devices that can send and receive files using 5G technology. In more detail, I'm aiming to design a PCB that includes a processor capable of handling...

I am trying to send PWM signals using STM32F100RBTx but it do not working. I double checked all the address but it is still the same. I wasn't sure if I was flashing at the begging but I configured the PB7 pin to be GPIO output and connected to a led and the led is working so I can flash it and...

Hi, I would like to power an embedded board that has USB-C input using a power supply with 5VDC output (8A). The cable I am using does not have the USB serial port but only the two 5V and GND signals. With this configuration the board does not turn on completely: is it possible that some sort of...

Im looking for a LCD display which is programed bitwise for example a 256x256 display will have 9 bits for x position and 9 bits for y position as well as power and any serial communication pins so 20-25 pins.Thanks!Also to be available in EU

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, I am using the Arduino Servo library to actuate two BLDC motors and ADK USB Host Shield to control them using a USB dongle controller (XBOX). But I am facing issues particularly in calibrating the BLDCs and lose the host shield. The most probable problem I could think of is there are some...

Hi everyone, I am currently a rising senior majoring in computer engineering. I wasn't able to secure an internship this summer so I wanted to come up with ideas for projects. One of my project ideas is creating a police speed gun that uses LIDAR to measure the speed at which a vehicle is...

Hi everyone!, im currently a student, i know about electrical circuits, basic electronics, digital circuits, basic digital design, microcontrollers, programming and other things, im a biomedical engineer and currently im working as service engineer (giving maintenance to medical equipment) but...

Greetings everyone, I´m a newly graduated Electronics Eng. and I´ve been working with components obsolescence management for 6 months now but I want to change my career focus to microcontrollers and embedded systems I do know basics for C programming, used MPLAB IDE X and Proteus while on...

This code is to simulate RFID reader working using AT89C51 in Proteus Software. Instead of RFID reader i am using Virtual Terminal for sending or scanning RFID, here in my case I am Typing ID in Virtual Terminal, string 'a' stores input and compares with existing string and gives Output. Problem...

Hi there, I want to use mcu for some automation, mostly i use mcu for controlling some stepper and servo motor and also some transistor but there is one problem that in my environment there is a lot of industrial 3 phases motors. What is the best mcu for my occasion? (Specially i can program it...

In my one project i want to give some serial number and want to store it in the flash for the first time while flashing. I don't want to build the project again for updating the serial number. Is it possible to update the address location in .bin using any tool command line and flash the...

Hi, I am connecting a sensor to PICAXE08M2 MCU. The sensor is read in pin C.4 and when it is off is 1.8V and 5V when it is fully ON. I need to offset the 1.8V. I need to write the codes in Basic. The ADC is 8 bit and the maximum value would be 255. My codes are below. Main: Readadc C.1...

Hi, I come from the background of microcontroller design. I am learning fpga design. Usually in the ucontrollers the total number of pwm is limited as per the vendors. In FPGA how can i determine the maximum number of pwm I can drive from a fpga. For example, currently i am working with...
