µC uses simple tool for angle measurements - 04/10/97 EDN-Design
Ideas....The circuit in Figure 1 uses a 2V, 2250-Hz resolver as an angle
sensor. The excitation for the resolver is irregular, using two
90�-phase-shifted, 900-Hz signals. (The stator is the primary
winding.]....[Design Idea by Lev Freidin, Patriot Sensors & Controls Corp,

µC-based one-shot has wide range - 06/19/97 EDN-Design
Ideas....The µC-based, digitally programmable, monostable multivibrator in
Figure 1 has more accurate timing than a conventional RC-based device
because a 20-MHz crystal controls the µC. The PIC16C54 is a low-cost,
high-speed,....[Design Idea by Yongping Xia, International Teldata Corp, Los

µP Displays 10 Bit Data on Three LEDs - 11/07/96 EDN-Design
Ideas....circuit in Figure 1 uses a PIC16C55 µP to read 10-bit binary data
and directly display data in decimal format on three common-cathode
LED displays. ...[Design Idea by Yongping Xia, Philips Lighting Electronics,
Torrance, CA] |

µP Socket Automatic ally Senses Upgrade - 03/03/94 EDN-Design Ideas....The
circuit in Fig 1 automatically senses when a user upgrades a Motorola 68040 µP
system with a 68060 µP, changing the µP's supply voltage from 5 to 3.3V. This
automatic voltage change is far safer than any manual scheme could be, and this
technique lets you easily adapt the circuit to other applications that must switch
between 5 and 3.3V....[Design Idea by Thomas Mosteller, Linear Technology Corp,
Lansdale, PA] |

12F675 as a Flip Flop - Code to make a 12F675 operate as a D-type or JK-type
flip flop. Since I implemented a D type flip flop using PIC Logic Elements
I thought I might go or way and implement an entire D type flip flop in a single
PIC. This uses edge triggered and port change status interrupts and was an
opportunity to have a play with interrupts on PIC(added 10/05) |

16 Bit PC Serial Port Receiver CMOS - This circuit was designed to control a
32 channel Christmas light show from the PC serial port. Originally designed
with TTL logic, it has been simplified using CMOS circuits to reduce component
count. It is a fairly simple, reliable circuit that requires only 4 common CMOS
chips (for 8 outputs),....[Bill Bowden's website] |
