Another PIC-based digital thermometer and clock

This DIY digital clock plus thermometer is designed by Joe Farr and is based on PIC18F25K22 microcontroller. The┬ácomplete construction details of this project including circuit diagrams, PCB layouts and PIC firmware are posted in his website. He developed his firmware using Proton PIC BASIC compiler, which is available for download for free for this particular PIC microcontroller. He uses DS1302 RTC for timekeeping and DS18B20 for temperature measurement. The temperature and time are displayed on four 2″ seven segment LED displays.

Amicus18: Arduino-style platform for PIC fans

Arduino needs no introduction; it is an easy-to-use yet powerful open source embedded system development platform that has gained huge amount of popularity in past few years, specially among hobbyists. The standard hardware consists of an 8-bit Atmel AVR processor with on-board headers providing access to its I/O pins. The processor is pre-programmed with a serial bootloader that simplifies the uploading of user programs to the on-chip flash memory without the need of any external programmer. Because of its low cost, user-friendly software development environment (open-source C/C++ like programming platform), rich set of libraries, and tons of resources available online, Arduino has become a common choice for electronics hobbyists these days. Hundreds of plug-in application boards, called Arduino shields, are also commercially available to extend the functional capabilities of the Arduino board. The growing influence of Arduino inspired others to build a number of different versions of it. Amicus18 is also an Arduino-inspired embedded system development platform designed by Les Johnson and introduced by Crownhill Associates; however, it uses a Microchip PIC processor instead of the AVR microcontroller. This article reviews the features of the Amicus platform.
