PIC Microcontroller Tutorials

These are Tiny Chips that integrate the Microprocessor and Peripheral chips in a compact size with low power consumption. PIC Microcontrollers from Microchip are the evolved computing digital devices that go into many gadgets and intelligent equipment. These are easy to program and reprogram and even protect your code or IP.

The PIC has the math power. The memory, the I/O ports are integrated in the chip like 8051. Some may remember that Microprocessors like 8085 and Z80 had all these functions in chips outside and used to consume more power. Then came CMOS and better IC technology. The 8051(now avr, atmega)and PIC Micro are entire boards in one chip.

delabs Notes -
 
This is an Educational Masterpiece, with more Relevance to Asian Students. I took my first steps with 8085, Z80 and later 8749. Then the 80C51. If you start writing code for 8080, you will want features which will come in 8749 and when you study 8749 and think of enhancements 80C51 will pop out as if they read your mind.

Once you work with these, then you can use all the new uC and uP easily. It is better you write code with as less EPROM or Flash as possible. This will help you make quality code. The smaller the code the more real time your firmware and lesser bugs.

8051 Macro Assembler ASEM-51

In 1979 Intel has introduced the 8051 as the first member of the MCS-51 family of microcontrollers. Today hundreds of cheap 8051 derivatives are available from dozens of manufacturers. This makes the MCS-51 architecture so interesting for professionals and hobbyists.

8051 Macro Assembler ASEM-51

Intel had also defined an 8051 assembly language with bells and whistles for all the subtle peculiarities of the MCS-51 core, and offered a well-designed 8051 assembler, the legendary ASM51. Unfortunately, Intel obsoleted all its MCS-51 development tools in December 1993. The original (and IMHO best) 8051 assembler was gone and no longer available! ....... - W.W. Heinz,



ASEM-51 is a two-pass macro assembler for the Intel MCS-51 family of microcontrollers. It is running on the PC under MS-DOS, Windows and Linux. The ASEM-51 assembly language is a rich subset of the Intel standard that guarantees maximum compatibility with existing 8051 assembler sources.

With ASEM-51 to Mars

"In the letter, they told me that they had used my ASEM-51 V1.2 to develop the motor-control software for a little Mars car prototype..."They had validated several 8051 assemblers, and found ASEM-51 to be the most reliable and best documented one.

Some Facts -

Modbus Protocol is a messaging structure developed by Modicon (Schneider Electric) in 1979. It is used to establish master-slave/client-server communication between intelligent devices. It is a de facto standard, truly open and the most widely used network protocol in the industrial manufacturing environment.

The semiconductor industry has implemented a Network Communication Standard and an Object Messaging Protocol using Modbus TCP/IP. This allows SEMI Sensor Bus compatible sensors to communicate with each other using Modbus TCP/IP.

Spinwave Systems’ Wireless Thermostat Controller is a drop-in replacement for almost any existing conventional non-communicating thermostat, re-using the existing equipment wiring. Thermostat functions and values are accessible remotely through an embedded web page of the Modbus Mesh Gateway or via Modbus communication.

Thus, the data gathered will be displayed on your phones."

Bluetooth Multimeter - Seeed Studio

Totally open source, including hardware, software & Android API. Learn how to create a Platform to connect smartphones with the real life.



The Bluetooth Multimeter is based on Atmega328 - Arduino Pro. It measures the voltage and resistance and current input from the headphone jack, and then sent these data via the Bluetooth frame.



This Bluetooth Multimeter is a portable multimeter, a device that gathers the voltage, resistance and current. and then sent these data to other device via Bluetooth, so, we could display the data through other devices, such as Android, PC and so on.

USB PIC a easy PC Interface

PIC18F4550 has a USB Interface easy to use, code or configure. This page will help in trying out this PC friendly PIC Microcontroller.

The CREATE USB Interface

The Create USB Interface is an open source microcontroller board that can be programmed in C, BASIC, or Arduino languages. This latest version is called the CUI32Stem, which is designed to work ‘hand-in-hand’ with the GROVE prototyping system including a wide range of sensors and actuators.



PIC18F4550

The PIC is the heart of the board. It's a programmable microcontroller with 32Kbytes of flash program memory and 2kbytes of general purpose SRAM. It has 13 A/D inputs and 18 general purpose I/O ports. On the CUI board, one of the general purpose I/O pins is dedicated to the "program" button to enter bootloading mode. You can use the remaining ports for anything you wish.
