SliderWriter
SliderWriter is a tool for Osmond PCB layout designers to make capacitive buttons and sliders. Chips using this technology are made by Freescale Semiconductor, Analog Devices, ST Microelectronics, Atmel, and Cypress Semiconductor. The button patterns can also be used for buttons using carbon impregnated rubber keypads.
