I finally succeded on programming my board, In windows and in Linux! YOur tutorial was very helpful, though I had to do somethings a little different It was the starting point for me too. I’m in 895c2 middle of a battle with this microcontroller. I hope to win in the end.

Hi, this info is very useful. I’m not finding one like you have. I’m just getting started, any advice appreciated. Yes you should be able to use STC89C54, there are also tonnes of cheap boards available in aliexpress, banggood, dealextreame, dhgate etc.

Any thoughts of why Ver 4. How to add them? I have a bit more going now. Now when attempting download I’m receiving a Connection Failed after the following: What would be the software with the same A letter in display for this programmer?

Great info, 8c952 there any way to erase the chip and try again if I screw up. My programmer says I can not erase, read verify. So when I screw up, I gotta use another chip, and I’m all out of blank chips Hi, Thanks, It has been a long time since I did anything with mcu but as far as I understand the programmer erases and rewrites every time you download a new program into the chip.

This can be done usually many number of time. I dont understand “My programmer says I can not erase, read verify.

Among those posts I’ve seen, this is the most particular one, and I think the blogger must have spent lots of time on it, thank you so much!

I also a similar board, but not sure, it just has no response in “checking target MCU”, already off the power and on the power it was working last night Thanks for the tutorial. Hi Martin, Thanks for the update, I have been taking a hiatus after my son was born, hoping to get back into MCU soon.


Will check out your link. I am exactly in the same 89c552 as you were.

AT89C52 Microcontroller

Everything is Chinese and my friend bought it in China because he had no idea what to buy. Mucrocontroller AVR board would have been a much better alternative. By reading this post I see there is hope. I could not found the USB drivers. I am using Windows7, 64 bit system. 89v52 you please help in this regard.

Microcontroller is an electronic piece of digital system that is discovered and developed after a computer.

AT89C52 | 89C52 Microcontroller Datasheet & Pin Description

It saves a set of commands, Programming that is subject to it before use. Unlike the analogue circuitry that is designed to perform a certain fixed function, and if you want to modify it requires a change in connections and in most cases this also requires changing the components. The microcontroller is used to perform a variety of different 89c552, and is used in factories and machines that are working on a set of steps and orders or instructions.

But this does not support Micrcontroller family. Any help would be appreciated.

After finishing my basics in electronics i wanted to try my hand at programming micro controllers and this post is a direct result of my adventure in learning micro controller programming. Read on If You are a newbie to micro controllers and want to learn the easiest way to program i. You can get more info from stcmcu.

The STC chips seems to be manufactured by a variety of other companies e. I think its better to buy a development board with the latest MCU i. I got a development board STC Kit which also supports microcoontroller through serial interface. It cost me about 30 CAD and comes with everything you need to start writing programs for MCU and to test mmicrocontroller programs.

The only snag here is that everything is in Chinese!!!

I had to use Google to translate to English. I have provided the details of all that i have learnt through this process. One good cross compiler is Keil. Although the demo has limitation on the size of binary generated etc. There are other commercial and open source compiler and IDE which you can use for Atmel Studio 6 free http: Go ahead and use the microcontroler source ones if you are kicrocontroller setting up the tool-chain i.


The above development boards supports programming using serial port and comes with a USB to serial adapter cable more on this later. If you are buying a universal programmer make imcrocontroller it supports the MCU in the development board and also has a good user manual in the language you understand. How to open device manager in XP?

Install Keil on your PC.

Keil has a device database which is used to select a specific target MCU mucrocontroller your program. Based on your version of Keil uv2, uv3 or uv4copy the corresponding CDB to kiel install and update the tools. Install the program download tool stc-isp-v4.

Create a C source file and add it to the project. Google on how to use Keil.

I just copied some code from the CD that came with the board, this displays numbers in the first 7 segment LED display.

You should not see any errors in the build output window. Build target once again to generate the hex file in the project directory. Open the hex file. I f all goes microcontrroller you should see the 7 segment LED display light up.
