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...

Hi everyone, I am a final year student who is making a dissertation on Field-Oriented Control (FOC) with a BLDC motor. I am having the issue that with the virus outbreak I have had to modify a lot how to carry out my dissertation. As a result, I do not know what to write about anymore. I would...

Hi everyone, I have recently bought an STM32 Nucleo-64 G474RE. I want to use this MCU for Field-Oriented Control (FOC or Vector Control) with a BLDC motor. I have seen there are many libraries available and there is the ST Motor Control Workbench tool available. But I am confused as to which...

I'm working on a custom microcontroller design based largely off of NXP's K64 FRDM boards as part of a larger project, and recently (despite the date on the schematic) finished what may be considered "version 1." As a brief background, this board will have a sibling layout embedded into a larger...

It’s not a secret that the code quality standards for embedded systems software are much higher than those for games, photo editors and others. The requirements have increased after cases when hardware having got out of control caused a lot of tragic situations and, at best, great deal of money...

Hello everyone! I hope I'm writing to a correct forum. I want to find out what is required to create my own mini computer by myself. I worked with microcontrollers and created some devices based on microcontrollers, but now I would like to go ahead and create my Raspberry-like device. My...
