Capacitive touch has been widely used in a variety of industries and applications, replacing the knobs and buttons that once controlled electronics with a smooth and intuitive touch panel. Touch control is no longer the new darling of high-end products, and consumers can now perform touch control on everyday devices such as headsets, remote controls, coffee makers and thermostats without having to pay extra for the interface. Microchip Technology Inc. has announced a new 2D touch surface software library that enables designers to easily implement touchpads using the company's 8-bit PIC and AVR microcontrollers (MCUs) and 32-bit SAM MCUs. This software library is available for free with any compatible MCU, providing a simple, low-cost solution for embedded applications.
The 2D touch surface software library is ideal for small touchpads and touchscreens, and it can run on existing MCUs on the device, so there is no additional cost. This eliminates the need for dedicated touch controllers, giving product designers the flexibility to add finger position tracking and gesture detection capabilities to the product, such as swipe and zoom. The touch library is provided through Microchip's code configurator, which includes the MPLAB Code Configurator (MCC) for PIC MCUs and Atmel START for AVR and SAM MCUs. Both software tools simplify graphics configuration and increase development speed with streamlined C code tailored to individual projects. The 2D touch surface software library is now available at Atmel START and will be available at MCC this quarter.
Intuitive, beautiful user interface is the key to product success. With the 2D touch surface software library, you can provide consumers with an interface experience comparable to smartphones without the need to integrate expensive operating systems. This software library is ideal for adding touch functions to a variety of applications in consumer electronics, automotive and industrial applications, such as smart speakers, steering wheels or thermostats.
Fanie Dvenvenhage, vice president of touch and gesture business at Microchip, said: "Capacitive touch has become mainstream, and we are seeing an increasing number of applications requiring low-power gesture-touch interfaces. The 2D touch-surface software library reduces the implementation of small touchpads and The difficulty and cost of the touch screen."
The software library gives the touchpad inherent low-power performance because the entire surface can be scanned in one go during deep sleep. Reliability is a fundamental requirement for touch functionality that provides continuous responsiveness and functionality by eliminating the effects of water and noise to meet the needs of automotive and appliance applications. The solution should be able to work in a humid environment and withstand 10V of conducted noise, in line with International Electrotechnical Commission (IEC) 6100-4-6 test level 3.
development toolsThe DM080101 Water Resistant Touch Surface Development Kit makes it easy to evaluate 2D touch surface software libraries. The kit demonstrates the water resistance and immunity of the touchpad, with two touch buttons, all controlled by the same MCU.

A gas sensor is a converter that converts a certain gas volume fraction into a corresponding electrical signal. The detector head regulates the gas sample through the gas sensor, usually including filtering impurities and interfering gas, drying or refrigeration, and processing the instrument display part.
Gas sensor is a device that converts the information of gas composition and concentration into information that can be used by personnel, instruments, computers, etc! Gas sensors are generally classified as chemical sensors, although this classification is not necessarily scientific.
