Hi , If anyone developed scheduler for atmel 89c52 microcontroller pls provide me the source code in either C or Assembly. my mymail id Thanks G kannan
voltage range is 50 V and it is 8 bits ADC can I find somewhere the assembly code for digital voltmeter(AC/DC) (made by atmel 89c52)
iam doing my miniproject using microcontroller atmel 89c51.its an examination clock that gives instructions to students like start the exam,one hour left,tie your papers,etc.i need to interface an rtc ,dac and speaker. i am a beginner,can anyone please help me.would it be better for me to use pic?

Hello Everyone, I am new member of this forum. i need help on microchip 23K256(Serial SRAM,SPI). i need to interface it with the 89c52 atmel microcontroller. as 23K256 works on 3.6V i need to translet TTL 5V logic to 3.6V logic using transistor logic. i am using bit-bang method for communication. has anyone worked on 23K256 ? if so please (...)
Thanks again to all who reply. You will find a attached file for the schematic which I designed. The circuit is designed to read 8 PT100 sensors on PC using parallel port. I need to use a micro controller instead and controlling 8 heaters concerning to the temperature sensors. Can you help me find the suitable micro controller supporti
Dear All please provide me a simple schematics of Philips 89c52 programmer. better if it is serial programmer (DB9) ( I think this is equal to atmel 89c52 ) your reply is much appreciated.
Please if you have more information about multiplexing 7-segment display more than 2 so please guide me i am using atmel 89c52 microcontroller.
Hi This is nice tool learning programing for newbie in quick way support atmel 8051 series of microcontroller 89c51,89c52 and 89c2051 this work as under. * Direct keyboard entry mode no need of P-C * Serial port intreface mode all detail and software in side the archive hope friends and newbie like this
89C51 ? 4K Bytes of In-System Reprogrammable Flash Memory ? 128 x 8-bit Internal RAM ? Two 16-bit Timer/Counters ? Six Interrupt Sources 89c52 ? 8K Bytes of In-System Reprogrammable Flash Memory ? 256 x 8-bit Internal RAM ? Three 16-bit Timer/Counters ? Eight Interrupt Sources First of all both microcontroller has been discontinued by
go through The 8051 Mazidi thats a very good book on 8051 programming n applies to atmel 89c52 Added after 4 minutes: since you plan to use stepper motors go through the foll. site or the pdf that ive uploaded
hi,their is many type of is some of it and the manufacture atmel corp : 89series (89c51,89c52,89C55,89S51,89S52,89s53,89s8252...) all of it have internal Eprom Cygnal corp : 8051 fast speed,Flash,A/D 12 bits Intel corp : 80C51GB , 80C51S1..... Philips corp: P89V51RD2.etc... SSI: 80X52,2XHDLC , version use for MODEM anothe
I had built and worked similar project using atmel 89c52 and RFID bought from The relay on board can be connected to any electromagnet to lock the door. But this kit doesnt communicate to any PC. They provide all details including schematics, PCB's and components with project description. Hope this will help you. The said kit is also
Hello I am facing a problem interfacing the Cirrus CS5450A to atmel 89C51/ 89c52 microcontroller. I want to know how to read data from the 5460A. The SCK, SDO, SDI pins are being read through T0, T1 and WR pins (Port 3 pins 4,5,6). I went through the datasheet of 5460 and tried some code, but the bytes read are some arbitrary value
im using microcontroller atmel at89c52. i need to make an interface with sensor via serial port I have used 11.0592 MHz Crystal but I can’t get baud rates 19200 Is there any problem with this code for serial please? ; FUNCTIONS/SUBROUTINES SERIAL1: MOV A,PCON SETB ACC.7 MOV PCON,A MOV TMOD,#20H ; timer1 mode 2 MOV TH1,#0FDH (...)
I have Keil uVision software for coding and making HEX file. Actually i am beginner for uController and i programmed successfully but I want to erase previous program and feed new program in same uC, problem is that how erase previous program which has been feed in uC. I have atmel 8052(89c52) uC. I programmed a simple program for 1Hz frequency
How do I connect or interface potentiometer. Can anyone interested to answer me? Thanks.
There is no AT90s52. you probably mean the AT89c52 which is the 8052 family (basically the same as the 8051). you can find a lot of info on or atmel website (datasheets)
I have some experience of working on the atmel microcontrollers (89c51, 89c52). Whenever i am on the internet (forums, websites etc etc) or read some magzine......every1 talks abt PIC micros....i wanna know that WHATS SO SPECIAL ABOUT THE PIC microcontrollerS, what PIC microcontroller can do and (...)
kiel is basically for atmel microcontrollers like 89c51 and 89c52 etc. and it has nothing to do with pic microcontroller.
Dear, Try AT89S Series,In system Programmable Series from atmel. Try PonyProg or ISPPROG Good Luck!
how i connect the stepper motor with 89c52 (directly or with interfacing with ic) what type of stepper are you using? you cannot connect a stepper directly to the micro since output current from ports is to small. you nee a driver. such as l297 etc
