A hex (code) upon us
In the recent Design Idea "Find hex-code values for microcontroller’s ADC voltages," we flubbed a key formula. The typo made the Design Idea seem less impressive than it actually is and prompted some colorful reader comments. We have no … Details... more...
Microcontroller as voltmeter, testing lithium - battery chargers, canceling common - mode voltage, and more
The circuit in "Microcontroller functions as voltmeter," by author Noureddine Benabadji is an extension of his previous Design Idea on how to use an analog input in a microcontroller lacking a built-in ADC (see "Microcontroller, JFET form … Details... more...
Design Ideas spark a variety of functional control circuits
If you need only a few nonvolatile gates, consider using a component common in analog- and mixed-signal systems, the digital potentiometer, instead of a PAL, GAL, or CPLD, as described in "Nonvolatile digital potentiometer gates logic signal.&qu … Details... more...
