Everyone in their daily life has been using knowingly or unknowingly embedded in machines like cars, TV, refrigerator, washing machine, etc. Many of you know the capabilities of microcontrollers and have worked with it. You should have programmed it using different programmers by manufacturers. Have you ever thought how does a programmer work? What is the basic principle behind it? Why do we have different programmers for different chips? In this series of tutorials we will try to get answers of such questions.
We will do all the operations which are done by a programmer like read, write, erase etc. We will work with the 89S51 microcontroller belonging to the. The same methodology can be used to program other members like 89S52 & 89S53 microcontrollers.
In this series of tutorials, we will perform every function a programmer performs one by one. Lloyd Banks Rookie Of The Year Mixtape Cover there. We will not use any software but rather use two controllers.
One is the target controller on which every operation will be performed and the second controller will be the master controller which will have the necessary codes to perform the different functions of a programmer. The objective of this exercise is to understand the concepts behind the working of a programmer and learn to design a programmer from scratch. If you are good at software designing you can design the software also for the programmer using any language. Bs En 12390 8 Pdf Converter.
After about 2 months looking, i can’t find any ISP circuit for AT89S51/52 based on Serial COM Port. Then I found this great circuit for PonyProg. Unfortunately PonyProg doesn’t support S5X micros so i google further to find any solution to this until google showed me a great site from a great man named Adam Dybowsky who wrote a programmer software (in Delphi pascal) and share his code on.
But one unfortunate again he does not support Serial COM in his program. After few checks i think i can mix this two solution to work together and here it is I’ve modified the schematic from original SI Prog, I add a line Buffer (74HC541) to stabilize levels from zener diodes. And i add pin header for LPT port also, so you can use this circuit just like other Parallel Port STK 200 compatible programmers.
