Re-Doing my Design for a circuit to control an invention using a Microchip PIC microcontroller chips.

In a previous article I described how I designed the circuitry to control functions of the asparagus harvester.  After bread boarding up a test circuit and doing some initial programming I decided a re-do was in order. I found I had a lot of unnecessary redundancy and I also decided to put the air regulation function on a separate chip from the main controller chip.  I did so because I want the air regulati ...

GPS to SD-Card Data Logger using PIC16F819 microcontroller

Description This project combines a GPS receiver module, a MicrochipPIC microcontroller and a Secure Digital memory card to make a GPS data logger. With a large capacity and reasonably long battery life it is a very useful device for logging GPS position for example for mapping with OpenStreetMap. In this picture the complete GPS data logger can be seen. On the top right hand side from front to back are: Th ...

Microchip PIC Microcontrollers

Implementing ICSP requires connections to a minimum of 5 processor pins: VDD, VPP (also MCLR\), SCLK (on RB6), SDAT (on RB7), and GND. VDD and GND are straightforward. In most applications, it is best to dedicate RB6 and RB& for SCLK and SDAT. This avoids potential complications when these signals are used during programming. Microchip shows a suggested circuit for MCLR\ involving a RC network and diode ...

USB Audio Streamer A Microchip PIC based USB sound card

INTRODUCTION The idea for creating a USB sound card based on a PIC came from discussions of other people creating one on the Microchip USB forum. The hardware of the card is based on all Microchip products. The software uses a modified version of the Microchip USB framework which is interrupt driven instead of the traditional polling. The device is a USB composite device. The first device is an implementati ...

Mork Microchip PIC32MX ICSP

Mork is adaptation of Nanu nanu Microchip PIC ICSP for the STM32 based vcc-gnd or Maple mini. Both STM32 boards are inexpensive boards which don't cost much more than the Nano 3.0 yet they are far more powerful. One complication though for the vcc-gnd, is that it comes with a serial boot loader which is not accessible via it's USB port. This means that another device is required to program the vcc-gnd which ...

Introduction to Microchip PIC Assembler Language – Part 2

With only 35 instructions to learn the Microchip PIC microcontroller assembler language is considered very efficient and easy to learn; you will not find such as Atmel AVR microcontroller CP (compare) and BRNE (branch if not equal) or BRGE (branch if greater or equal) on the PIC microcontroller assembler language dialect, instead it’s just provide us with a very simple bit test and skip one line instruction ...
