The PCF8578 is a low power CMOS1 LCD row and column driver, designed to drive dotmatrix graphic displays at multiplex rates of 1:8, 1:16, 1:24 or 1:32. The device has40 outputs, of which 24 are programmable and configurable for the following ratios ofrows/columns: 32¤8, 24¤16, 16¤24 or 8¤32. The ...

SelectionDemo also has code (not included in the preceding snippet) that changes the table s selection orientation. By changing a couple of boolean values, you can make the table allow either column selections or individual cell selections, instead of row selections.

Using Gaussian elimination to solve linear equations.
// In this version, we allow matrix of any size. This is done by treating
// the name of a 2-dimensional array as pointer to the beginning of the
// array. This makes use of the fact that arrays in C are stored in
// row-major order.
Parking Lot Simulation:
Parking lot attendants often park cars bumper-to-bumper, several cars deep. This maximizes the number of cars they can fit into a parking lot at the expense of complicating the process of retrieving someone s car when they want to leave. Consider the case of a person wanting ...
