I have one application the need to be a kind of touch sensing but needs to work perfectly with water running on touch area.
mTouch from Microchip seems to work in my application, however, that pages states:
Microchip’s mTouch™ Sensing Solution provides a free and easy method for designers to add touch sensing to applications utilizing PIC® microcontrollers without the cost of fee-based licensing and royalty agreements. Being a source-code solution further helps engineers quickly integrate touch sensing functionality with their existing application code in a single, standard microcontroller, thus reducing the total system cost associated with current solutions.
Does I really need to use Microchip MCU to use that sensing technical idea? Does anyone implemented it with AVR?
I already investigated Atmel Qprox touch sensing technology dedicated IC but them may give problems detecting water.
I work in a small company in Portugal, coding C for AVR. I love AVR because of available Free Software tools like the GCC-AVR and AVR-Libc and support for GNU/Linux. I don't like Microchip because of inverse situation.
We would prefer to use AVR because we have hardware programmers and debuggers for them, also build tools, and not for Microchip MCU.
