Circuit and software provide accurate recalibration for baseline PIC microcontroller’s internal oscillator - (Design Ideas - EDN, 5/1/2008  A simple circuit and an assembly-language program allow you to recalibrate the internal oscillator of a PIC microcontroller. (electronic design idea added 06/07/08)

Circuit Controls ratiometric or simultaneous Power up of multiple rails - 05/13/04 EDN Design Ideas  /  (added 1/05)  Many applications use FPGAs, AS ICs, or DSP chips, which usually require multiple voltage rails, typically two: the core voltage and the I/O voltage. The core voltage is usually lower than the I/O voltage. Guidelines for determining how to power up two or more voltage rails depend on the part and the manufacturer you use....

Circuit for measuring motor speed uses low-cost components - (Design Ideas - EDN, 11/08/2007)  A microcontroller-based circuit provides both an LCD readout and an analog motor-speed output. (electronic design idea added12/07)

Circuit Provides 4 to 20 Ma Loop for Microcontrollers - 05/27/04 EDN Design Ideas  /  (added 1/05)The 4to 20-mA current loop is ubiquitous in the world of controls in manufacturing plants. Discrete logic, microprocessors, and microcontrollers easily cover the digital portions of control schemes. Interfacing a 4to 20-mA output to a rudimentary microcontroller can be problematic.

Circuit provides Watchdog for microControllers - 12/26/02 EDN Design Ideas  /  (added 1/05)The watchdog circuit in Figure 1 uses a single NAND Schmitt-trigger IC. The circuit is more cost-effective than dedicated, commercially available watchdog ICs. The circuit generates an active-high reset signal upon power-up and remains in a low state as long as the control input receives pulses. Whenever the pulsing at the control input stops, whether the circuit is in a high or a low state, th......
