Basic PIC16/17 Oscillator Design - Microchip Application Note
Published 10-Apr-02 (app note ) The oscillator circuit is one
of most overlooked areas of microprocessor circuit design. Components
are usually selected based on manufacturers? tables. If circuit starts
up and works, fine, no or thought need be given to it, right? Wrong.
Many conditions can negatively affect performance of your design.....

Binary Coded Decimal Bcd Clock - The clock circuit above uses seven
ICs and 19 LEDs to indicate binary coded decimal time. The LEDs can be
arranged (as shown in example above) so that each horizontal group of 3
or 4 LEDs represents a decimal digit between 0 and 9 and each individual
LED represents a single bit or (binary digit) of the value. Binary
digits....(electronic schematic) |

Circuit Conditions Variable Duty Cycle Clock - 02/17/97 EDN-Design
Ideas: The circuit accepts an input clock of any duty cycle and
generates any desired duty cycle at the output. You need to add only one
flip-flop to the earlier design to generate an arbitrary-duty-cycle
output. You can use the circuit to correct a non-50% input to a 50%
output or to create a non-50% output from any arbitrary input duty
cycle |
