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...
Hi,
I am currently working with a sensor platform to measure IAQ. One of the sensors that I am using is the ZMOD4410 developed by Renesas to measure TVOC. I am having trouble with the sensor's I2C. In the datasheet it says that the implemented transmission protocol is similar to conventional...
As shown in the diagram, I am trying to connect two power sources to load. The battery source is for emergency in the case of power outage of the wall source. I want the switching to be instantaneous with no interruption of power.
What is the best solution to this problem? Is there a board...
At work, they are using this structure to protect an analog pin on a micro-controller from overvoltage.
I simulated the circuit and wired it up to test it (physically), but the output is linear in both (which I expected). One engineer at work assures me this works, and that once V5 = V6 + 0.6V...
Hello everyone.
I came across while reading the opto-isolator technique used for electric isolation in embedded systems/ Integrated Circuits design that " Opto-isolator is not recommended for electric isolation in power applications IC's mainly due to its dV/dt sensitivity". So I would like to...
i am facing problem while programming PIC16F18875 using pickit3. I am using mplab x on windows 10. I bought new chip and and from first i am getting problem.
currently i am giving power from pickit3 which is approx, 4.5V.
I checked the connection for MCLR, VDD, VSS, PGD and PGC pin.
I have...
I have Atmel controller which requires a 12V pulse and 5V pulse during flashing. I have a 12V supply and derived 5V from it using a regulator. But I want to know how can I give the 12V pulse and 5V pulse on the same pin.
We can manage to give pulse single voltage level using NPN transistor but...
Hello Everyone,
I need help in to generate feedback for fan regulator to the controller.
1. AC Fan require 1 phase Ac supply (230VAC/50Hz)
2. Controller require DC voltage in range of 0 to 3V3
3. System is able to support all type regulator, there different type's...
Hello,
I am currently trying to get SPI data transfer between the MPC5744p and a Raspberry Pi 4 to work.
I'm using the SPIdev python toolkit to send the value 26 over to the MPC, using the attached SPItest.py script.
To receive this, i've modified the code of the SPI_MPC5744P example to only...
Hello everyone, I'm a graduating Elektrical Engineering student, for my last year project I have to develop an prototype for an automated testsystem for electronic drive lines.
I started this thread to get help and tips about building this system.
First of all , I should make some dynamic...
