In the keypad HDL encoder, the ts bit array represents a tristate buffer.
In the digital clock project, a MOD-60 BCD counter is made from a MOD-10 counter cascaded to a MOD-6 BCD counter.
In the keypad HDL encoder, as long as all columns are high the ring counter is enabled and counting.
In the digital clock project, the ENT input and RCO output can be used for synchronous counter cascading.
In the digital clock project, when it is 11:59:59, AND gate 1 detects that the tens of hours is 1 and the edge trigger clock moves the display to 12:00:00.
In the keypad HDL encoder, after releasing a key the ring counter resumes its counting sequence.
In the frequency counter, a pulse shaper block is needed to ensure that the unknown signal, whose frequency is to be measured, will be compatible with the clock input for the counter block.
The frequency counter measures frequency by enabling a counter to count the number of pulses of the incoming waveform during a precisely specified period of time called the sampling time.
The full-step sequence always has two coils of the stepper motor energized in any state of the sequence and typically causes 30° of shaft rotation per step.
In the digital clock project, the AHDL block codes are connected using graphic design files.
