#18 Programming the AT89S52 Using Arduino Uno.

This video describes how to program an AT89S52 microcontroller using an Arduino Uno. This is useful if you are considering building your own AT89S52 projects. I have referred to a few similar videos when I was researching for this video. I like to take this opportunity to mention one video which I found very useful and informative. The link for this video is as follows:
NematicsLab KZbin: • How to program 8051 us... .
NematicsLab Instructables webpage: www.instructables.com/How-to-...
Resources:
Files you need to complete the programmer:
I have uploaded the command line as a text file and the AVR8051.conf file here:-
drive.google.com/file/d/1XqGD...
The hex file that I used in this video is also included in the above link.
The AVR8051.conf can also be downloaded from the NematicsLab Instructables webpage.

Thank you for your friendly statement. Please keep up the good content.

[@_tamilinithu_]

Thank you 👍

[@vooiyap]

I am glad you like it and I hope you find the videao useful. By the way, I have build a shield for the programmer and I will put it up in the next video.

[@adrianpopescu8464]

Thank you for this series. Very helpful for to put a beginner on track. Can you please explain the needed of the 10u capacitor in parallel with the switch between +5V and R1?

[@vooiyap]

I am glad that is useful to you. The purpose of the capacitor and the resistor is to perform an auto-reset on powering up the microcontroller. I hope that helps.

[@ujjwalsaha609]

Plz sir tell me, how to know which program uploaded before

hello sir.. thanks for give us very important knowledge ... sir can i upload same way AT89C52 microcontroller

Hi, I have not try this with the AT89C52. Have a look at this video. It may help.: kzbin.info/www/bejne/Z37cf35sl9pliq8

Sir, please explain, bootloading processing of pic16f72 microcontroller interfacing with Arduino Uno

[@vooiyap]

Hi, thank you for the suggestion. Regrettably, I have no plans to look into the Pic microcontroller in the near future.

[@deeptimaanbanerjee6330]

Facing a weird issue... when the capacitors to the crystal oscillator are connected the 8051 does not work... whereas the capacitors when removed the microcontroller runs smoothly...

[@vooiyap]

That is weird. I cannot comment on the issue until I have seen the circuit you have built.

[@vooiyap]

Hi are the other end of the capacitors connected ground?

[@surajkumar-ty9zy]

Could you please tell me the easiest way to lock at89s52.i really want to lock my code as nobody can read it..

[@vooiyap]

Hi sorry for the late response. I do not know of any easy way to lock AT89S525. The following website might provide some clues: www.engineersgarage.com/at89s51-52-isp-programmer-lock-bits-setting/

Hi I’m facing error when trying to key in the code for method 1. It says “syntax error at C:/AVR8051.conf:27”, what could be the problem?

I don't think so. Please check the forums.

Is it okay if I change the 33pf caps with 22pf caps?

[@vooiyap]

It should be okay. The capacitors are used to ensure oscillation.

[@candrasniper3404]

@@vooiyap okay, anyway it's pretty similar with the atmega328 min circuit.

[@shawon97256]

But the Crystal connection is with pin 18 and 19.

Hi, could you kindly state your question.

[@santhoshkantharaj8822]

I have sent a comment about 4 days back, but no reply is received. cmd type is working fine, but gui method I could not make it. The momory is exceeding 2kb of flash. Will it still run since keil says max. flash size for demo version is 2kb ? pl. camment on this. con't we send you my mail id and mob.# in this comment?

Hi I am apologize for not responding earlier. I have been quite busy and I have not check my channel. It will be good if you can send me more details to this email: [e-mail].

how to do same on ubuntu?

[@vooiyap]

You need to download and install Linux version AVRDUDE. However, I can't find a Linux version AVRDUDE_GUI_8051. You need to check this.

[@gurumultitask9979]

where is the pin number of VREF and Vin??

[@vooiyap]

Hi, thank you for your question. Vin is located on the Arduino Uno board - just above the ANALOG IN pins. However, I am not sure which VREF pin you are refering to. By the way, VREF and Vin are not used in the project.

Why not set fuse bit and lokbit ?

[@vooiyap]

Please refer to the following for information on lockbits: www.engineersgarage.com/at89s51-52-isp-programmer-lock-bits-setting/

[@April2023-fb6pf]

@@vooiyap thats mean that arduino ide automaticly set fusebit lok bit for new ic ?

[@vooiyap]

A Fuse Bit configures the Operational Mode/Functional Mode of the microcontroller (MCU) at the time of the 1st power up initialization when no instruction has yet been executed. The state of a fuse bit must be altered before “Programming the Lock Bits” associated with read/write protections of Flash Memory and EEPROM Memory of the MCU. Once, the lock bits are programmed, the state of the fuse bit cannot be changed. The option that is left is to erase the chip (chip erase brings the lock bits back to their default values) and then set the fuse bits.@@April2023-fb6pf

Hello Sir, Is C programming necessary to write programs for these boards or we can use assembly language also? If not, then are there boards other than Arduino which allow assembly language programming? Please help
