.. designed for the limited resources of ATtiny10 and ATtiny13 , but should work with some other AVRs as well. Due to the low clock frequency of the CPU, it does not require any delays for correct timing. In order to save resources, only the ...
.. used architecture that allows such miniaturization is the I 2 C bus. Comprising only a bidirectional data line, SDA, and a clock line, SCL, this bus requires no chip selects or other additional connections. Microcontrollers from NXP, ...
.. filter. The MSMXVHF also features a selectable low-pass/band-pass switched-capacitor filter with operation up to 1 MHz (clock at 12.5 MHz). The output of the mixer is ac-coupled externally to the input of the filter, while the output of ...
.. for each device must suit their operating voltages. You can use the level-shift circuit in Figure 1 to adjust an input clock signal to the proper logic-high and logic-low voltage levels, including negative voltages. This property is ...
.. networks to distinguish between them. The design described here is much simpler. The microprocessor pin is connected to the clock of a multiple-output sequential counter (Figure 1). In its simplest form, this state machine consists of two D ...
.. guarantees the precision of the ohmmeter. External digital-control circuitry can measure delta time by counting the clock periods between the start and the stop events. At the end, the control circuit can generate a reset signal for ...
.. scheme achieves the desired characteristics with minimal parts count. IC 1 , a chopper-stabilized amplifier, features a clock output. This output switches Q 1 , providing drive to the diode-capacitor charge pump. The charge pump's ...
.. signal advances both the wiper and the counter. The pin of the DPP responds to negative-edge triggering, and the clock input of the counter responds to positive-edge triggering. If the signal driving the line is a pulse (a common ...
.. was purely analog and had no “10-MHz reference input” on the back to allow it to be synchronized with the ADC clock. The result is substantial spectral leakage in the FFT, so that it looks more like a circus tent than a single ...
