Full touch mobile phone with Oscilloscope and Signal Generator for Electrical Engineers (patent num: IR 66411)

Having a phone that can provide all in one electronic lab was always a dream for me, so at very first year of studying in university I decided to make one. learning how to work with ARM processors was a good start. At first I try to design an Atmel Sam7X256 evaluation board to learn how to use it. You can see its picture below.

Little by little I learned how to drive LCD and MMC. After a while I wrote a simple OS for ARM7TDMI core with a help of my friend. following pictures shows the Oscilloscope function of a prototype model of the phone.

Final version of the phone composed of following items:
1- Light operating system which was written by me and my freind (M.Baseri). Compatible with ARM7 and ARM9 and ARM11 series.

2- Hardware support for both Oscilloscope with working frequency up to 100 KHz and Signal generator capabale of generating square,sine and triangle waves ranging from 10Hz to 2MHz

3- sending and recieving SMS, Dial and answer calls, entertaining programs such as touch paint and so on.
