February 14, 2008[Ideas For Design] Inexpensive MCU Replaces Dedicated Backup-Power Controller
Portable battery-powered applications sometimes also permit operation from the power grid. If so, the application must choose the appropriate available power source—the grid or the battery. If the battery is rechargeable, the system also requires a charging circuit. Instead of employing a dedicated charge controller for the backup-power controller, designers can choose the more economical option of using an inexpensive eight-pin microcontroller, available...
May 24, 2007[Ideas For Design] Eight-Pin Microcontroller Handles Two-Digit Display With Multiple LEDs
Eight-pin microcontrollers offer numerous peripheral features. However, the maximum number of I/O pins available is often limited to six, since two pins would be required for the chip's power supply. So, it can be challenging to design systems based on these devices, especially if they involve a significant display requirement. For instance, controlling a large number of LEDs is a problem with eight-pin microcontrollers, unless you resort to a method called...
December 9, 2002[Ideas For Design] RISC Controller Backs Frequency Counter
Frequency measurement, often vital to design engineers, is the driving force behind this idea. Here, an AVR RISC controller-based circuit can measure the frequency of digital signals. It employs the PC as a user interface and sends the measurement...
February 7, 2000[Ideas For Design] Roll Your Own Electronic Lock
Electronic security locks, popularly known as “dongles,” are commonly used to deter software piracy. This idea describes a simple yet-powerful design of such a security lock using the linear feedback shift register (LFSR) principle. The lock, which is...
