Hi All, I'm looking for a controller with wifi connectivity. The controller needs to interact with camera and touch screen input. It needs to have battery backup and few I/O to operate any 5V supply device. NOTE: I'm completely new to this field. Looking forward for a good starting point. Thanks everyone in advance. Regards, Raghav
It sounds to me as if you're looking for a smartphone with an USB switching device? There's a camera, a touschscreen and an USB Port already there. All you'd need is a custom App and a USB Extender with a few digital I/Os. Correct me if this isn't the easiest way to obtain a device.
Oh, btw, USB switching devices can be either selfmade with e.g. the V-USB software for AVR: https://www.obdev.at/products/vusb/index-en.html or it could be a commercial device like the IO Warrior: https://www.codemercs.com/en/io-warrior
Hi Matzetronics, Thank you for the reply. I hope that could be nice. But as I mentioned I'm really new to this area (I work on CNC controllers). This project is for a hobby and I may need to develop it later. I may need to use a Bar-code scanner as well. I'm not sure of how feasible it would be with a smart phone with respect to improvements. Also I need to think of programming aspect. Kindly provide your thoughts on the same. Regards, Raghav

Either way, most of the hardware you mentioned is already built into these devices and they come with Bluetooth connectivity as well which could be useful for external devices like an external scanner or ohter input. Its just a thought and might be easier than a controller like e.g. the STM32F429 which has TFT driving, USB and e.g. SD Card ports. If you think about writing your own software from scratch, have a look at the Discovery Boards from STM, like the above mentioned F429 or the latest F7 series. http://www.st.com/en/evaluation-tools/stm32-mcu-discovery-kits.html?querycriteria=productId=LN1848
Thank you so much for the suggestion. I will have a look over the boards this weekend. So they mention Aurdino uno connections. It means that it has a aurdino board to support i/o connections? If bar code reader is wired, then can we connect in stm f7 boards? And how about the camera connections? Sorry for too many silly questions. Once again thanks a lot.
