Hi All,
Just like my STM32F103 'diagnostics bootable binary' that you flash and then run from a menu, I've made one to play with the Touch Sensor on a STM32F0 Discovery Board.
Flash the binary, connect a 47nF cap to the board, and play with some sensors, it seems a very reliable technology to me. You do need a usb-3.3v serial dongle as the F0 Disco has no USB.
