dsPIC30F6014 and accelerometer card Example

Date: 09-03-2007
The example shows how the signal from the sensor is sampled and how the information on the accelerations along the X and Y axes are used for controlling the cursor on a GLCD. The example also covers the calibration of the sensor (determination of the offset voltages along the X and Y axes and setting the pin PORTD.0.

Manchester signals decoding project

Date: 14-09-2006
Manchester code carries information about bit rate and this is very useful to make transmitter and receiver synchronized. However, two levels per each bit require double the bandwith for transmition.

Tachometer project

Date: 23-05-2006
Program measures the rotation period based on a pulse input and calculates RPM NOTE: Interrupt Procedure is NOT used as the CCP2 interrupt flag is set regardless of whether interrupt is enabled. Since the CCP2IF is checked in the Main repeat loop, there is no need for the MP3 Interrupt Procedure. Determines rotation period time based on Timer TMR1. Note: this works for an 18F452 with a 4 Mhz crystal.
