Revision as of 16:23, 11 January 2016

To complete projects in the book "Embedded Computing and Mechatronics with the PIC32 Microcontroller" (Lynch/Marchuk/Elwin, Newnes 2015), we recommend the following "kits."

Minimum Electronics Kit

We recommend this kit for simple interfacing with the NU32, as described throughout the book.

  • a wire stripper
  • a multimeter
  • 22 AWG solid hook-up wire, typically including black (ground), red, and at least one other color
  • a selection of breadboard-ready 1/4 W through-hole resistors, but at least (these resistances)
  • a selection of breadboard-ready through-hole capacitors (e.g., ceramic), but at least (these capacitances)
  • OSRAM SFH 310 NPN phototransistor
  • Kingbright WP7113SRC/DU red LED
  • etc., if anything else

I think we can collect together several of the items above into a digikey cart and share the cart, so people can get the cart with a single click. Here is a sample digikey cart, though interestingly it gives an error when you open it.

Useful Optional Components

The following equipment is used in code samples in the book.

  • a portable oscilloscope and function generator, such as the nScope
  • a 16x2 LCD screen (HD44780-compatible controller chip)
  • potentiometer, pushbuttons, etc.
  • etc., if anything else

The Brushed DC Motor Control Kit

These items are needed to complete the projects associated with a brushed DC motor.

  • a brushed DC motor with no gearhead that draws less than 1 A at stall when powered by 6 V, with an incremental encoder (as many counts per revolution as possible, preferably at least hundreds). No gearhead makes it easier to characterize the motor without having to worry about high friction in the gearhead. You can search surplus sites for such motors or try these recommendations.
  • a 6 V battery pack to power the motor (6 V is not critical; other voltages are possible, provided the motor does not draw much more than about 1 A at stall)
  • 20 ohm 5 W power resistor
  • the motor control board, consisting of a TI DRV8835 H-bridge chip, the MAX9918 current-sense amplifier, and a PICxxx? encoder counter chip that speaks SPI
  • a motor mount to mount the motor securely to the table
  • an inertia bar to attach to the motor to vary its load
  • etc., if anything else

Other Components Referenced or Used in the Book

These components can be sourced from various suppliers if you want to use them as described in the book:
