UL Isolated Self-Powered Sensing - DN204 Design Notes
(Linear Technology) (app note added 1/06) |
|
Ultra Low-cost Programmer for AT90S family - With this programmer
you can program AT90S1200, 2313, 2323, 2343, 4414, 4434, 8515,
8535….(electronic circuit added 4/05) |

Universal Nicad/NiMH Charger - Sometimes its more convenient to
recharge batteries 'in place' rather than removing them and putting them in
an external charger.....[Luhan Monat - Mesa Arizona] |
|
Universal OS PIC Programmer - This programmer requires only a
basic terminal program capable of uploading an ascii PIC HEX file. It does
not matter what operating system or computer (MAC, Win98, XP, Vista, DOS,
Linux, etc.) is used to talk to it…. [Luhan Monat - Mesa Arizona] |

Universal RC5/RC6 Transceiver - The IR receiver: When the
TSOP1736 (IR receiver) receives an infrared (IR) signal from a RC5 or RC6
remote control (like Philips) burns LED1 (green).….(electronic schematic

Unused µC ADC pins find second life - 02/03/00 EDN-Design Ideas....Some PIC
µCs, such as the 12C67X and 16C7X, have more than one analog input channel. If you
don't need all the available channels, you can use the unused channels as
general-purpose I/O. For example, you can use unused ADC pins for power-on status
reading and as an output in normal operation. In Figure....[Design Idea by Kannan

Unused 8051 pin gets assignment - 01/04/96 EDN-Design Ideas....In an
8051-based system without external program memory, the program-store enable (PSEN) pin
is useless. However, you can indirectly control this pin using software. To do so, you
execute the move-constant- (MOVC-) instruction-implementing table look-up.n an

Use 8051's power down-mode to the fullest - 07/06/00 EDN-Design Ideas....The
8051 series µCs offer idle and power-down modes, both of which you invoke by setting
appropriate control bits from the code. For instance, a 5V, 12-MHz Atmel AT89C2051
consumes approximately 9 mA in active mode, 1.8 mA in idle mode, and only 12 µA in
power-down mode. Although power-down savings outperform those of the idle mode by two
orders of magnitude, the....[Design Idea by Jerzy Chrzaszcz, Warsaw University of

Use a microcontroller to design a boost converter - 4-Mar-04 Issue of EDN
Boost converters, like other switchers, have traditionally received their control
signals from a dedicated circuit. However, a recent trend is to integrate simple
switching-power-supply building blocks into generic devices, such as microcontrollers.
An excellent example of this concept is a microcontroller that combines digital and
analog circuitry and makes it easier to build simple power supp....[Design Idea by
