How DoesCapSenseWork? AllPSoCMCUs supportCapSensecapacitive-sensing. The figure below shows the self-capacitance of each electrode modeled as CSXand the mutual-capacitance between the electrodes modeled as CMXY. TheCapSensecircuitry internal toPSoCMCUs converts these capacitance values into equivalent ...
WATCHDOG TIMER TIME BASE SETUP OPTION = 0xCB;// Prescaler assigned to WDT T1CON = 0xC5;// Timer1 init T1GCON = 0xE3;// Timer1 Gate Enabled / WDT time base TMR1GIF = 0;// clear gate Interrupt flag TMR1GIE = 1;// enabl...
How does an accelerometer work? An accelerometer works by utilizing an electromechanical sensor that is designed to measure either static or dynamic acceleration. Static acceleration is the constant force acting on a body, like gravity or friction. These forces are predictable and uniform to a large...
How Does It Work? MEMS Sensors are composed of a suspended mass between a pair of capacitive plates. When tilt is applied to the sensor, the suspended mass creates a difference in electric potential. The difference is measured as a change in capacitance. ...
With an increasing demand for tougher security, smartphones have unanimously adopted superior capacitive and optical-capacitive hybrid scanners. These scanners work by using an optical image of your fingerprint, combined with capacitive sensing to detect the presence of a real finger. The falling cost...
Like optical scanners, capacitive fingerprint scanners generate an image of the ridges and valleys that make up a fingerprint. But instead of sensing the print using light, the capacitors use electrical current. The diagram below shows a simple capacitive sensor. The sensor is made up of one or...
How does Arduino PulseIn work Note: pulseIn and pulseInLong use the same algorithm to measure a pulse, so the description here applies to both functions Lets assume that we are going to measure the high portion of a signal. To measure a pulse, the function has to wait for any existing pu...
touchscreen technology, and how does it work? surface acoustic wave (saw) touchscreen technology uses ultrasonic waves sent across the screen's surface. when you touch the screen, some of the wave energy is absorbed, and the sensors detect the change, pinpointing the location of the touch. ...
AN4312 Application note How to design surface sensors for touch sensing applications on STM32 MCUs Introduction This document describes the layout and mechanical design guidelines used for touch sensing applications with surface sensors. Capacitive sensing interfaces provide ma...
How does touch screen technology work? Touch screen technology works by sensing the points where you make contact with the touch-sensitive surface of the device. Depending on which part of the screen you touch, different kinds of commands can be executed. For example, tapping an icon on your...
