We consider a multipurpose n-step network with cross resistors that is a profound problem that has not been resolved before. This network contains a number of different types of resistor network model. This problem is resolved by three steps: First of all, we simplify a complex graphics into...
Too many button clicksButtons and tactile switches are frequently used in many projects involving micro controllers; one of the most frequent issue is related to unwanted multiple transitions when the button is pressed once.Tactile switches as well as pu
Lattice Semiconductor has announced the expansion of its small FPGA portfolio by adding new logic-optimized Lattice Certus-NX FPGA devices. This release introduces the Certus-NX-28 and Certus-NX-09 models, available in various package options that prioritize power efficiency, size, and reliability wi...
These sections provide a deep description of the main STM32 timer features used to build the example application. They also describe the architecture of the used source code. The objective of this application note is to present in a generic and simple way some use- cases of the STM32 timer...
Care should be taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the isolator on the printed-circuit board do not reduce this distance. Creepage and clearance on a printed-circuit board become equal in certain cases. Techniques such as...
A rheostat is a variable resistor made of resistance wire and often three terminals. The rheostat was invented in the 1840s by English scientist Sir Charles Wheatstone.Answer and Explanation: The purpose of a rheostat is to vary the resistance in a wire, such as when you want to control ...
Maximum operation voltage of 25V and maximum dissipation of 50mW Reduced size of final equipment, higher component and equipment reliability Small size and light weight Suitable for high density print circuit board assembly Operating temperature range of -55°C to 125°C ...
Pull-up/down resistor: It sets the status of GPIO pin in IDLE or in condition of invisible input signal. The Pull-up resistor will connect the GPIO pin to the positive to set it as the default high-level status. While the Pull-down resistor will connect the GPIO pin to the GND to ...

PxREN only controls whether the functionality is enabled. PxOUT in this mode is the one that controls whether the resistor is pull-up or pull-down. A word of caution is in place. The pull-up and pull-down capability of the MSP430 is limited, with a resistance of about 20k to 50k ohm...
