In this website you will see several examples how to simulate PIC microcontroller circuit using PROTEUS VSM such as interfacing c,7-segment,switchs etc.[more]
Interfacing an Analog-to-Digital Converter (ADC) with Linux via the parallel port is fairly simple. There two major areas that need to be addressed - hardware and software. The hardware consists of the parallel port, an ADC, and an analog signal source. The software programmed in ‘C’ language.[more]
This article discusses how to overwrite bytes in the CGRAM to display custom bit-map graphics on a Hitachi HD44780-compatible character LCD display. A method is described of transforming a raster image to an array of values that are a monochrome bit-map representation of the original.[more]
The concept is : fully software controlled RS232 reception and transmission for PIC16F8x.Display of received ASCII characters sent from PC via RS232 and their corresponding decimal value on the LCD. Microcontroller sends feedback of received characters back to the terminal window. When the PIC terminal is idle, it sends a status message ‘@’ to the PC every 2.75 seconds.[more]
This article introduce the Waldic (water & air laptop direct input cooler). This device is a dual mode home made laptop cooler. It was made for the purpose of watching movies without being disturbed by the annoying fan. The following pics are mostly self explanatory.[more]
