Open source; Hardware compatible for SSI standard (synchronous serial interface); Cyclic reading of sensor data up to 64 bit per slave; Transmission of status data, parameter, measured temperature value, configuration description, etc.
For example, a query command that performs an AC Volts measurement on a digital multimeter, using the meter's 10 VRMS measurement range, and displaying the measured voltage value with 4-1/2 digits of resolution, would be written as "MEASure:VOLTage:AC? 10,4".
Rotary encoder for angle-measuring devices marked in 3-bit binary-reflected Gray code (BRGC). The inner ring corresponds to Contact 1 in the table. Black sectors are "on". Zero degrees is on the right-hand side, with angle increasing counter-clockwise. To avoid the above problem, Gray coding is used. This is a system of binary counting in which ...
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
When a percentage is referenced with a non-linear taper, it relates to the resistance value at the midpoint of the shaft rotation. A 10% log taper would therefore measure 10% of the total resistance at the midpoint of the rotation; i.e. 10% log taper on a 10 kOhm potentiometer would yield 1 kOhm at the midpoint.
While quite similar to normal potentiometers, digital potentiometers are constrained by current limit in the range of tens of milliamperes. Also, most digital potentiometers limit the voltage range on the two input terminals (of the resistor) to the digital supply range (e.g. 0–5 VDC), so additional circuitry may be required to replace a conventional potentiometer, (although digital ...
This arrangement is used to measure and regulate the speed of rotating objects, including disk drives. A Hall effect sensor (also known as a Hall sensor or Hall probe ) is any sensor incorporating one or more Hall elements, each of which produces a voltage proportional to one axial component of the magnetic field vector B using the Hall effect ...
A potentiometer being calibrated and then measuring an unknown voltage. R 1 is the resistance of the entire resistance wire. The arrow head represents the moving wiper. In this circuit, the ends of a uniform resistance wire R 1 are connected to a regulated DC supply V S for use as a voltage divider.
