MICROCHIP HI TECH C COMPILER ARCHIVE

The archive contains the Hi-Tech C source code, Protel 99 schematic and pcb files, and. This code was used to drive a demo board that I made for a University of Canterbury demonstration day.ДЇrom readme.txt: The demo board consisted of a 16F84, five 240V 3A solid state relays, an RS-232 port, a Dallas 1-wire interface port (using a RJ-11/12 connector), and a number of LEDs вЂ¦ It is a simple program that uses nested if statements to do a BETTER job than the original logic did, by the addition of some error trapping and a timeout delay for safety reasons (and to save money because Liquid Nitrogen is not cheap). PIC12C509 logic gate replacement for nitrogen filler by Mike PearceДЇrom readme.txt: This project was a really quick replacement for an old logic gate that had faulted and could not be fixed. c file pertaining to TRIAC/IGBTS and EMI standards. Also TRIAC or IGBT output is available by commenting out the unwanted option.There is more info in the. Timing for 50Hz and 60Hz has been included вЂ“ selectable by commenting out the unwanted option.

This has samples of how to use the interrupt routine for TMR0 and INT. Phase control is a simple even time-slice method, with 255 levels of output. RA0 is an active LOW output to an opto isolator to drive a TRIAC or IGBT circuit. RB0/INT is used for the zero cross detection. PIC16F84 based TRIAC / IGBT phase controller for 50/60Hz brightness control by Mike PearceДЇrom readme.txt: A single channel phase controller for a PIC16x84 10Mhz. Mike tracked down the problem and had the system adapted to counter for the glitches, due to this nice piece of design work.

MICROCHIP HI TECH C COMPILER SERIAL

They set up a PC with a serial program, and came back the next day to see exactly when the flow had dropped. If the pulses dropped below a pre-determined threshold, it would log the date and time out to a serial port.

It would measure the flow, based on pulses from a flow meter. So, Mike Pearce designed a water-monitor. This means the run would have to be started again. Unfortunately, as the story goes, there was a problem with the water supply controller, and it would periodically drop pressure and the machine would shut down. It was water cooled, and each run would take 24 hours and cost the client a lot.

HereвЂ™s the scenario: at University of Canterbury, New Zealand, they operate a hugely expensive X-ray crystallography machine. PIC16F84 based pulse monitor with date/time output to an RS232 serial port by Mike Pearce They give a window into the way he does his code, and perhaps you will learn a few tricks from him рџ™‚ Enjoy! These projects partially cover the 8+ years of work he performed in the Chemistry Department and as a hobby. He is an excellent programmer for PIC micros, and manages to make them do things that I barely thought were possible. These sample Hi-Tech C projects were supplied by Mike Pearce while he was working at the University of Canterbury, New Zealand.
