C Programming Jobs and Contests - Page 5

Are you looking for a stellar C developer? Despite its age, C remains one of the most popular programming languages in the world, but finding the right developer can be difficult. C has been used to write a wide range of software, including operating systems, device drivers, banking software, games, and even GPU-based learning algorithms. The sheer range of projects that C has been used for means you need to find a developer that's familiar with your particular problem.

So how do you find that developer? On Freelancer.com there are thousands of C developers that are available for hire. To find the right one, all you need to do is post the details of your project. Within minutes our talented C developers will see your project and will start responding with detailed proposals about how they would complete your job.

PLC STEPPER MOTOR - open to bidding Objective: On/Off Control: A stepping motor is started by a momentary push button (Start) and stopped by a stop button. When the motor stopped, all coils must be de-energized. Speed Control: Connect four switches to the input bit 0 to 3 to simulate a thumb-wheel switch. Insert a MVM (Masked Move) instruction to read the switch status, multiply the input data by 2 and store it as timer preset. Use the timer to control the duration of between pulses. Direction Control: Use a single pole switch to control the direction (moving forward or backward). Angular Displacement Control: Connect one more switch to the input. If the switch is ON, the motor should run continuously. If the switch is OFF, the motor will turn number of revolutions depending on the data read from the input bit 0 to bit 3. Procedure: o Create the ladder diagram for above function o Assign I/O address to all I/O’s o Download the program to PLC o Connect all I/O to PLC and test the program o Ask your instructor to sign your Lab. Note: Start the circuit design with on/off control, fixed speed, one direction and continuous mode, then add speed control, direction control and angular displacement control to the circuit one at a time. 19 C Programming, Microcontroller, PLC & SCADA, Assembly, x86/x64 Assembler Apr 22, 2017 Apr 22, 20172d 12h $506

I would like to hire a Programmer I need you to develop some software for me. I would like this software to be developed for Windows using .NET either in C# or VB. The software is for a mini ROV project and will run on a PC which will control the ROV. The project is NOT commercial and is privately funded. I am 60% there but I do not have the time to complete the software myself. This is NOT a WEB development project and requires a stand-alone application. Here are the essential requirements: 1. Read control data from a Logitech USB joystick and transform this to RS232 ASCII codes to be transmitted, via USB HID to a microcontroller board. 2. Receive a video feed over USB and display it on the UI, with an overlay of compass and depth data. 3. Receive sensor data from the microcontroller (via RS232 over USB HID) and display it on custom controls on the UI. 4. Provide user controls on the UI for controlling various utilities on the ROV. These will be variable or boolean depending on the function. 5. ALL aspects of the software must to be fully commented in English. 6. All RS232 (ASCII) communication word maps will be provided to the successful bidder. 11 C Programming, Visual Basic, .NET, Software Development, Programming Apr 22, 2017 Apr 22, 20172d 7h $206
