  1. Dusan Ponikvar EDN When you need an analog output from a microcontroller that does not have a digital-to-analog converter (DAC), you can connect an external DAC chip. But for a cheaper solution, use a pulse-width modulated (PWM) output and add a ...
  2. Analog Devices Circuit Note CN-0038 Circuit Function and Benefits This circuit provides a programmable gain function using a multiplying DAC and an operational amplifier (op amp). The maximum gain value and the temperature coefficient are set by ...

  3. Victor Khasiev, Linear Technology Design Note 553 Introduction Data loss is a concern in telecom, industrial and automotive applications where embedded systems depend on a consistent supply of power. Sudden power interruptions can corrupt data ...
  4. Abel Raynus EDN A microcontroller requires dc operating power in the 2 to 5.5 V range, an amount that a battery or a secondary power source can easily supply. However, in certain situations, a microcontroller-based product must operate directly ...
  5. Francois AUGER Philippe Fretaud EDN Many previous Design Ideas [1, 2] have shown how to use the Charlieplexing technique [3] to drive as many LEDs as possible with a minimum number of I/O lines. This Design Idea shows how you can drive three LEDs ...
  6. Andreas Freiherr VishayOpto Creating a “Magic” Cat Doorbell with the TSSP4P38 Proximity Sensor Leonie and her family live in a building with seven other families. Like many cats, Leonie loves to explore her surroundings, and after ...

  7. Ricardo Jiménez and Juan C. Ángeles Electronic Design A basic microcontroller can be used to convert a sensor's analog output into a pulse train, thereby making the output compatible with standard digital I/O ports. When the need ...
  8. Stephen Woodward EDN An inexpensive way to implement high-resolution digital-to-analog conversion is to combine microcontroller-PWM (pulse-width-modulated) outputs with precision analog-voltage references, CMOS switches, and analog filtering ( ...
  9. Part 1 Software The software for the datalogger is download section (PIC_DATALOG_V00d). I use Mikroc Pro PIC compiler from mikroElektronika , the libraries of this compiler are great! Especially the FAT32 library, it allows to manage the micro SD ...
  10. Part 1 - Hardware: Schematic, PCB and case. Hi all! I’m continuing here with the last board I design and now I’m continuing testing. It’s a battery-powered small datalogger based on a PIC18F2620 microcontroller (Figure 1). The ...
