...C and GCC compiler Please answer these questions in your bid: 1. What is your experience with signal processing for analog inputs? 2. What is your experience with microcontroller interfaces to other logic ICs and experience with I2C and SPI? 3. What is your experience with output to serial and USB and ensuring data is transmitted with integrity
We have arduino microcontroller picking up sensor data Ambient temperature (BME280) Ambient humidity (BME280) Pool temperature (MAX6675) And sending it to a mysql database using GET command It works and logs well but i’m a hobby-ist rather than professional so was wanting someone to audit the code and make sure that is done in the most robust
We are building a prototype device that will use 3 - 5 Omron D6F-PH sensors to collect air pressure/air flow data, process the data using a STM32 microcontroller board, or similar, and store the data to an ascii file. We need someone who can help make sure the sensors are best configured for our application and program the device to allow us to store
...both circuits: * Have a BOM cost of under $10 (I’m hoping for a BOM under $5 in quantities of 500). * Both circuits should be powered by [url removed, login to view] and communicate with a microcontroller using [url removed, login to view] IO lines (Atmel Sam3x is the micro I’m using). * Components should be available on Mouser or if there isn’t a reasonable option t...
I am working on a project using a PIC16F1829 microcontroller and I am using MPLAB X IDE V2.35. I already have my schematic and project written in C, but the SPI port and the UART are not properly initialized. I want to give the source code of my project to a freelancer to modify it and to properly initialize the PIC so theses peripherals will work
...Windows platform. We need it to be ported in .NetCF C# for (Compact Framework for Windows CE, WEC7 to be exact). The software actually uses RS232 port to program a microcontroller from a PC. We are trying to replace the PC and use our Windows CE terminal instead. It is expected that you have Windows CE simulator to test the port. As you don't
A microcontroller that can read 125kHz / RFID card and trigger respective relay up to 32 outputs. Two operational modes as below: 1) Operation mode 1: Read and assign relay output ( 1 to 32) and store in reference memory. Be able to store up to 10,000 card ids. 2) Operation mode 2: Read card and output respective relay accordingly.
[url removed, login to view] Something like this, exactly like this. but i need to test each lcd for 30 minutes. and the pass and fail parameters may be different. It needs to work reliably and efficiently under stress. above all it cannot be expensive. NO FAKE BIDS, THE PRICE YOU BID IS THE PRICE I PAY.
...Details include price and item name. That profile should also contain a field that contain the total price of all scanned items. The PCB will also be interfaced with a simple LCD that shows the total amount of products scanned. The user can remove a product from his stack, that will be done by turning a switch and rescanning the item that is to be removed
Multi-Zone Quartz Lamp controller featuring intensity control via phase angle comparison.
The motor protector counts with one LCD, 4 potentiometers and I'm using a Arduino Pro Mini for prototyping with Arduino IDE. And also a MOSFET. I already a the code written by myself but came to a wall where I don't know how to overcome. The LCD shows which is the lowest voltage (undervoltage protection) and also the highest voltage (overvoltage protection)
I am expecting two pages with IEEE style references. With latest research on Smart Solar Street Light controlled with any microcontroller, modules and sensors. All references must be not older than 4 Years, and from journal/conference paper (goes from the oldest one to the most recent one).
...AT90USB646/647 MCUs. It reads data from multiple i/o pins and transmits it over serial interface. I need that code to be rewritten for use on a lower-end microcontroller (m328 or m168). Of course, such microcontroller has less i/o pins, so you'll need to modify the code to take data from shiftIn and shiftOut registers. I'm attaching: - current schematics
