I need you to develop some software for me. I would like this software to be developed for Linux using C. I am currently looking for someone to write a GUI application for Linux. The application is for a digital eye testing chart, like the one you see in optometrists when you 'read letters from the top line'. You would need to supply the complete source code including commenting written in C if possible. Please see the rough project outline below: Operating System: Raspbian stretch with Desktop V4.9 Hardware: Raspberry pi 3b Video output via hdmi Screen Resolution: 1920x1080 Completely offline - no wifi/bluetooth functionality Screen resolution is key in all concepts of this program (menus/tests) Sony ‘XMB’ style look with colour themes (set by user) 7 key tests to be created along with Snellen, Tumbling E, Numbers, Duochrome balance, Cross cylinder dots and point of fix tests, will explain in further detail if we go ahead with the order. Need a seperate quote for an additional 40 tests to be created. Mostly black and white tests but some colour Need to show on screen for tests: Name of the test Current contrast ratio (adjustable on button press) Acuity scale (size of text, adjustable on button press) Letters must be able to accurately scale at button press according to algorithm Randomize letters on button press although remove some sequences (swear words) Randomize must never repeat (within reason) Must be able to play multimedia from sd card Presets can be saved to sd card and loaded on startup Error logging Possibility for different languages in the future - hidden from user for this build. If you think you could be up for the job or have any further questions, please feel free to ask. Thanks.

Hi, I have immense experience with Raspberry pi 3 programming and raspbian os. I have developed many applications using C and linux and my experience concludes to more than 5 years. I have even developed digital signage applications using raspberry pi to play videos, feeds, images and streams on screens. Developed camera based detection applications using raspberry pi and image processing. I will develop the initial tests and will provide the quote when you provide details of the tests. Thus i am the perfect option for this application. Looking forward to hear from you soon. Regards

I can definitely build this for you, sadly not on that price range and also if I would do it I'll go cross-platform creating the app with React. About the UI design (similar to sony XMB) is perfectly doable, the resolution is not going to be a concern given that we know the resolution of the device so the whole UI will be designed specifically for that resolution. The test, of course, I know some of them but for others, I'll need support. "Letters must be able to accurately scale at button press according to algorithm" I suppose you'll provide the algorithm. All in all is completely doable and I'll be more than happy to help you out with this one if you think the change in the programming language is a good thing (consider updates and changes in the OS or future support for other devices (tablet, etc). Please don't hesitate to write to me so we can discuss this further. Best regards Oscar

hi, if i understand correctly your description, you want a digital eye examination using the raspberry pi. i can help you accomplish this project and have experience at those technologies. also i can help you making the control of the test fully automatic, and even controlled/changed using a pc if you choose to. (you didn't mention it but you may want to do it) i think you don't need to code it in C, in my opinion, python would be much more efficient for your purpose. i am a signal processing developer i have a lot of experience with the raspberry pi, and with image processing, i've done projects ranging from robotics to image analysis, stereo vision and more. please contact me for further information.

Hello Sir, The eye vision chart using Raspberry pi is my own product. I have already sold so many product based on this. I am having all the image to test the eye vision in the high resolution. The system is made on Raspberry PI Revision 2 on KODI OS. I have given the control using RC5 Remote control. No need to waste any single hour as my product, code, hardware diagram everything is ready with me. Sir, Let's have a talk once and see the demo once. I want you to see the demo once before you start the project with me or with anyone else. I will be happy to work with you. I am ready to be hired and start working for you now.

Hi, We have our expertise on raspberry pi, C, Linux Internals, Python, HTML, Java. We could take up this project and finish at best. We understood the project requirement and we have few questions on this. 1. Will you provide the icon for GUI ? and what about the Font Files? 2. Is there a particular reason for going with C programming. Since raspberry pi has any other rich language support like html, java and so on... 3. Request you to share us the detailed document for the 7 tests to get the elabrated view: Snellen, Tumbling E, Numbers, Duochrome balance, Cross cylinder dots and point of fix tests.

Hi, I can do the job, I have more than 7 years of experience in embedded system and software development in general, i have developed many Gui interfaces most of them run on the raspberry pi. for this project, we can use qt framework it's totally cross-platform based on C++ it will enable us to develop fully functional, responsive and scalable application. i have a lot of samples of my previous work i can share some of them also i have a pi board so i can test the whole app on it. Best Regards, Mo.
