AT89LP2052 and AT89LP4052 Parallel Port Programmer

Posted on 13 Oct 2008

AT89LP2052 / AT89LP4052 Parallel Port Programmer
This 2052 / 4052 programmerย�design uses the parallel programming mode via Parallel Port. Only parallel programming can re-enable the ISP Fuse. This programmer is alsoย�usefull if you need to write the user fuses to disable the XTAL Osc Bypass fuseย�-ย� e.g. toย�test the LP2052ย�in existing 2051 hardware designs.[more]

Microcontroller with LCD, Keyboard and Compact Flash

Posted on 15 May 2008

Microcontroller with LCD, Keyboard and Compact Flash
An Atmel AT89C51AC2 microcontroller development board with Optrex DMC 16207 16×2 LCD display, 4×4 keyboard, speaker and 64MB Compact Flash storage. Low level C hardware interface functions are implemented so the keyboard, beeper and display are accessed with high level printf() and scanf() routines. Short filename DOS files may be read from, and written to the root of the FAT16 formatted Compact Flash media.[more]

Interface card for Cypress’ CY7C68013 USB microcontroller

Posted on 08 May 2008

Interface card for Cypressโ€™ CY7C68013 USB microcontroller
This is a rather simple project. Cypress Semiconductors manufacture a microcontroller called CY7C68013. It is based on a 8051 processor, and has a lot of special functions and built-in peripherals, the most interesting one being its USB interface.This project is supposed to result in a CCD camera for astronomical purposes. developing software for the controller is VERY easy. The code is written on a PC, then downloaded to the CY7C68013’s internal 8 kB SRAM through the USB interface. No hassle with EEPROM burners or slow Flash memory.[more]
