  1. Eric Schlaepfer Electronic Design Many devices require programming through a serial bus, such as I 2 C. The programming can be done during final test, after the circuit board has been assembled. In many cases, the pins used for programming can then ...

  2. Soumitra Bhattacharjee EDN In PIC microcontrollers, the MSSP (master synchronous serial port) module uses multiplexed pins for the I 2 C and SPI peripherals. There is typically no issue using either of the two peripherals. But what if both ...

  1. Peter Khairolomour Electronic Design The circuit that's shown in Figure 1 implements a programmable 0- to 20-mA precision current source. The REF192 low-headroom 2.5-V voltage reference (U1) can source up to 30 mA. An AD5280 digital ...

  2. David Conrad Electronic Design In this Idea for Design, placing this circuit setup between the battery V DD bus and the PIC microcontroller allows you to execute in-circuit programming while protecting the application circuit. Many PIC processors ...

  3. Dhananjay Gadre EDN Batteries are the typical power sources for portable-system applications, and it is not unusual these days to find microcontroller-based portable systems. A variety of microcontrollers operates at low power-supply voltages, such ...

  4. Stephen Woodward EDN The enduring simplicity of PWM DACs will always earn them a place in the designer’s cookbook, but slow response time and the problem of PWM ripple tend to limit their appeal and utility. The usual way of attenuating PWM ...

  5. Tom Gay EDN Most current microcontrollers offer I/O ports that can change their functions during program execution. As outputs, the circuits can sink and source reasonably large amounts of current. This Design Idea shows three alternative methods ...

  6. Rex Niven EDN It’s almost a corollary to Moore’s Law: Next year, microcomputers will have more features, and the software team will have bigger ideas. Unfortunately, though, the number of output pins will stay the same. Finding even one ...

  7. Dan Meeks EDN Most current microprocessors, DSPs, and field-programmable gate arrays integrate hardware and software resources that support either or both of two common interface standards SPI (serial-peripheral interface) and I 2 C ...

  8. Jim Brannan EDN Combining PWM with a small R-2R ladder improves both. It reduces PWM ripple significantly and increases the DAC’s resolution. In this Design Idea, an eight-resistor array and three output pins construct a modified R-2R ladder ...
