I sorry about the project materials still under documenting. I will try to combine all the materials in such a way that becomes fully a part. Because I have so many job to do, especially the business plan, (business things is not good for me.), I may further delay the project documentation. Sorry!

DS1620 Digital Temperature sensor
Interfacing the DS1620 via the comport, measure temperature form -55 to +125. This note introduces the software for interfacing a 8052 microcontroller to the DS1620 digital temperature sensor. The DS1620 communicates via a 3-wire serial digital interface. Software code is provide that reads the DS1620 temperature register and calculates high-resolution results.

LCD_Driver 16x2 HD44780 This is the function code used to modify the standard c function "printf" by replacing the function "putchar" to suit the LCD driver HD44780. By adding this file, LCD panel with a chipHD44780 can print out a string using the standard c function "printf". \n, \r, and roll down will be included.
