Extend PIC Microcontroller‘s RAM by without using EMI

Introduction Virtually all PIC microcontrollers have some banking mechanism to extend addressing to additional memory space. But this external data memory is not directly addressable (except in some high versions of PIC18 devices, which include PIC18F8520, PIC18F6620, etc.). In this post we describe easy to implement external memory interface for PIC microcontrollers. Theoretically most of the PIC microcont ...

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 ...

Microcontroller Clapper Switch

Introduction I always thought the clapper so cool. For those who are lazy like me, turn on or off the bedroom light without getting out of bed, simple clap your hands is amazing. Thinking about it I projected one for me. Several projects of clappers can be found on the Internet, and most of them do not use microcontroller. I chose to use a micro planning future updates, such as turn on or off the light with ...

8051 Microcontroller Overview & Hardware – Tutorial #1

The intel 8051 series 8bit microcontroller, originally introduced in 1980, remains popular and has had perhaps the longest product life of all such devices. It has become the industry standard for real-time and Boolean control applications. While some (who should know better) have said that the 8051 is dead, it continues to be a viable choice for both design upgrades and new applications as faster, more adv ...

Interfacing RTC with Microcontroller

Have you ever wondered how your PC and phones keep track of time even when the device is turned OFF? Well there is a Real Time Clock (RTC) that is kept powered even is the device is turned OFF. Once the device is turned ON and connected to the internet the device connects to a NTP server (Network Time Protocol) and updates the time and date. This post is intended to give a little insight over these RTCs and ...
