PIC-Programmer 2 for PIC16C84 etc.

This Programmer is powered by the RS-232 and it works with RS-232 levels at only < ±8.6V. It programs PIC12C5XX, 12C67X, 24CXX, 16C55X, 16C61, 16C62X, 16C71, 16C71X, 16C8X, 16F8X and ISO-CARD's with ASF. Other serial programmable chips by adapter. The high Vpp is obtained by using negative voltage to drive the chip. The voltage is stabilized with zener diodes. They do not need voltage drop as if a voltag ...

Ultra-easy use of 64-pin TQFP PIC18F6620 using TQFP-to-DIP PCB from VOTI

A while ago I purchased a batch of 18F6620 TQFP PIC Microcontrollers at a ridiculously low price. The barrier to use of TQFP packages is, of course mounting these SMD packages effectively alongside the ‘normal’ components enthusiasts tend to use. At the time I set about and designed a header, and test motherboard for these chips, and although my header was successful, repeatability was variable using the ra ...

Using Microcontrollers ( Microchip PIC)

Many people using Arduino or some other development board in their projects, instead of making their own board with microcontroller because they simply don’t know how to design PCB with microcontrollers. What microcontrollers need in order to operate? This time I will be focusing on two most popular 8 bit micro architectures: PIC Microchip . In reality what many people are afraid of is really simple to do. ...

Embedded System for Automatic Washing Machine using Microchip PIC18F Series Microcontroller

The design uses the PIC18F series microcontroller. All the control functionalities of the system are built around this. Upgradeability is the unique feature of this system. Control card hardware and software allows the manufacturer to add or remove the features as per customer requirement and model. Thus once the whole system is designed it is very economic in large quantity production. Single-phase motor i ...

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 ...

Breadboard module for PIC16F628A

Here’s another breadboard module that carries a PIC16F628A microcontroller. The power supply pins and the I/O ports of the PIC16F628A microcontroller are accessed through male headers. It can be easily plugged into a breadboard and is very useful for quick prototyping. It frees up a lot of space on the breadboard since the oscillator, reset, and ICSP circuits are already built on the module. It is different ...
