PIC16CS4 Programmer

Posted on Jan 30, 2013

Most of you will certainly already installed on your computer one of the many software tools move freely from hand to hand and is suitable for programming the PIC 16C84. One of the most popular of this kind is the RIR02 of Silicon Studios. The circuit described below, is perhaps the simplest PIC programmer that can work seamlessly with the program RIR02. This guide allows RIR02 communication with the programmer, through the parallel port (Centronics).

The components are the building are minimal and have very low costs (The most expensive of these is the connector Centronics)! The integrated 74LS06 (Inverter anoichtousyllekti sixfold) is responsible for Data exchange between the parallel port and the microcontroller to be programmed. To this end, three of data lines of the door, the OO, O1 and O3 impose reasonable conditions on the pins of the microcontroller, but only after reverse and isolate the gates IC1c, IC1 and IC1f respectively. More specifically, the line OO provides the data to be written in component, the L1 the necessary clock pulses and O3 pulse programming. On the other hand, the data returned by the PIC the PC, driven by the inverter IC 1 b BUSY line clamp Centronics. The complete set will be scheduled should be connected to terminals K2, K3 and K4 in the following way: The point of the K3 OATA the RB7 pin of the PIC (pin 13) pin CLOCK in the K3 RB6 pin of PIC (pin 12) Pin's K4 MCLR MCLR pin on the PIC (pin 4) The +5 V pin to pin of K2 YOO the PIC (pin 14) The GROUND pin of K2 in the VSS pin of the PIC (pin 5). Spike + nip the K4 accepts the programming voltage of the integrated, which should have a value of 12 V. The 2 LED illuminates as applied programming pulses. The diode D 1 protects the base of the transistor T1 by the voltage programming. The programmer requires two external voltages: one of 12 V (voltage programming PIC) and one of the 5 V (Feeding the 74LS06 and LED).
