I am upon chosing a microcontroller for a PCB board project. MCU collects data from capacitance to digital converter (from a capacitance sensor) via I2C and I would like to pass that data to a host PC - via USB seems to be the most convenient. In the future there may be some filtering done on the data in the MCU, but in my project i focus primarily on the hardware part.
I am fairly new to the whole embedded/hardware design. On my research I found out that MSP430 may fit in my needs but I am not sure, there are so many of them even in msp430 family.
My main concern is programming, because as I understood in many MCUs, additional hardware is required for programming/debugging. And the examples I found all use some kind of development board - I need to develop complete standalone system on PCB board without any unnecessary components. The MCU part of the board should (there are 3 parts - electrodes, cap-to-digital converter, mcu for communication) not cause excessive electromagnetic interference.
I am looking for some guidelines, because I can't seem to find information on what I need.
