ADC for programmable logic uses one capacitor - 12-Nov-09 Issue of
EDN Use a capacitor's charging and discharging time to sense a user
input.... [Design Idea by Jef Thoné and Robert Puers, Katholieke
Universiteit Leuven, Leuven, Belgium' Edited by Martin Rowe and Fran
Granville] |

Assembly code reads IDE drive parameters - 05/09/96 EDN-Design
Ideas....Many older disk drives and most current models that interface with
the ATA or IDE standard have readable configuration tables. These ....

Autoranging circuit simplifies hardware & software - 07/22/99 EDN-Design
Ideas....A natural approach to autoranging is to use an inverting op amp and switch in
one of N feedback resistors at a time for a gain of A=-RF/RO (Figure 1]…. [Design Idea
by Dana Romero, Phonex, Midvale, UT] |

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 by Bill Bowden] |

Bridge-temperature measurement Allows software compensation - 08/17/00 EDN-Design
Ideas....Bridge transducers are notoriously temperature-sensitive. When the
temperature changes, almost everything else varies with some parameters increasing and
some decreasing. The TCS (temperature coefficient of span) is generally negative for
piezoelectric pressure sensors,.... [Design Idea by John Wynne, Analog Devices Inc,
Limerick, Ireland] |

C function turns PC into serial bus master - 09/02/96 EDN-Design
Ideas....The UARTs built into most microcontrollers support a "9th-bit" communications
mode. If the master sets the 9th bit of a character it transmits, the slaves then
interpret that character as a slave address, not as data. The 9th-bit mode simplifies
master-slave communications by using character protocols over multidrop serial lines,
such as the RS-485. A PC's UART family (for example, the 8251 or 16550), however,....

C Program Calculates checksums - 02/15/01 EDN-Design Ideas....To ensure data
integrity, it's wise to frequently calculate file checksums. The C program in Listing
1 calculates the checksum of a file using a 16-bit CRC (cyclic redundancy check). The
program assumes an 8-bit byte size. The routine reads the file.... [Design Idea by Ken
Levine, Airshow Pacific Systems, Kirkland, WA] |

C Program simulates industrial temperature system - 11/10/94 EDN-Design
Ideas The program in the ZIPfile attached to EDN BBS /DI_SIG #1621, written in Borland
C, simulates industrial-temperature-data display and control. It displays four
independent channels simultaneously…. [Design Idea by Jyoti Vandana, World Friends
Design Group Kalpakkam, Tamilnadu, India] |
|
C routine detects single high bits - 07/04/96 EDN-Design Ideas....Sometimes,
you need to be able to verify existence of just one high bit in a word.
This ability can be useful, for example, to verify wher just one bit in a mask of
mutually exclusive flags is set or if an incongruence exists in a word representing a
set of input contacts. The most obvious way to implement this verification is to use a
loop.... [Design Idea by Maurizio Denna, Eurotherm SpA, Guanzate, Italy] |
|
C routine speeds decimal to binary Conversion - 11/24/99 EDN-Design
Ideas....A previous Design Idea ("Program provides integer-to-binary conversion," EDN,
March 2, 1998, pg 110) describes a C/C++ function that provides integer-to-binary
conversion. The function, named cintbin/classicC, implements a conversion in a
straightforward way.... [Design Idea by Giovanni Motta, Brandeis University, Waltham,
MA] |

Comparator has programmable limits - 12/31/69 EDN-Design Ideas....The
circuit in Figure 1 combines a dual buffered D/A converter and dual four-input
comparator to configure a comparator circuit with a digitally programmable window
center and width. The circuit has three outputs that separately indicate the
comparison states: within the window,....[File contains multiple circuits.
