4bit alphanumeric LCD interface 8051
Atmel AVR and 8051 series ISP programmer
This ISP Programmer can be used either for in-system programming or as a stand-alone spi programmer for Atmel ISP programmable devices. The programming interface is compatible to STK200 ISP programmer hardware so the users of STK200 can also use the software which can program both the 8051 and AVR series devices. Figure 1 shows the circuit diagram
ADUC845 12MIPS 8052 Flash MCU + 10-Ch 24-Bit ADC + 12-Bit DAC
AH1751 is a single-digital-output Hall-effect Sensor for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an Amplifier to amplify Hall voltage, and a Comparator to provide switching hysteresis for noise rejection, and an open-collector output pre-driver. An internal band-gap Regulator is used

Classic 8051 Memory Layout
The CODE and CONST memory classes are typically stored in ROM that may be either off-chip or on-chip. The CODE memory class is used for the actual program code while the CONST memory class is used for constant variables declared in code space. In addition, up to 32 code banks may be used for code banking applications. While these are technically l

This schematic is provided in the hope that it will be useful, but without any warranty, not even a warranty of merchantability or fitness for a particular purpose. The address bus in this schematic is connected in an unusual way, which is optimized for simpler point-to-point wiring and board layout. For anyone building the board using wire-wrap o
USB AVR In-System-Programmer (ISP)
Nowadays, USBis the most popular connection connection between PC and peripherals such as AVR programmers, printers, scanners etc. For that reason I had to modify my old serial AVR In-System-Programmer (ISP) to work with USB connection. You can say, "use a USB to Serial adaptorto connect your AVR ISP with your PC". Yes, that could be a solution bu

Free 8052 Microcontroller Based Projects
Personal Safes are revolutionary locking storage cases that open with just the touch of your finger. These products are designed as "access denial" secure storage for medications, jewelry, weapons, documents, and other valuable or potentially harmful items. These utilize fingerprint recognition technology to allow access to only those whose fingerp
Atmel 8051 Flash Based Microcontroller Programmer
The Atmel Flash devices are ideal for developing, since they can be reprogrammed easy and fast. If you need more code space for your application, particularly for developing 89Cxx projects with C language. Atmel offers a broad range of microcontrollers based on the 8051 architecture, with on-chip Flash program memory.

Decimal Counter Using Two 7-segment displays and an 8051
The purpose of this lab is to implement a decimal counter which counts from 0 to 99. You will have to write a C program for the 80X51 micro-controller. You will then compile your C program using C51 compiler and burn it unto an 8051 stand alone chip. You will also have to do some wiring in this lab. The 8051 chip requires some connections to funct
