C Programming Jobs

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. Like C, the whole process is fast, efficient, and can scale up if you need it. So why not give it a shot? All posted projects are obligation free, so if you aren\'t happy with the proposals, you don\'t need to choose one.

I need help removing any redundant functions that are not being used, and creating a library with all the remaining functions. This will alllow the file to be less cluttered as it will call its functions from the library file. The ESP32 firmware controls a device with an ADXL accelerometer, an optional GPS unit, ethernet or wifi connectivity, LEDs and a buzzer. After starting up its peripheral devices it checks if ethernet is connected, if not it uses Wifi with Smartconfig protocol, then connects to AWS. This is done using AWS certificates stored in the SPIFFS memory. Once connected to AWS it collects the ADXL FIFO buffer of accelerations every second and sends them t...
