Part 1 of 3: USING AVR MICROCONTROLLERS FOR PROJECTS

The AVR 8535 microcontroller and its new version ATmega8535 are versatile, high-performance but low-cost chips. This article series covers typical applications of this processor illustrating its power and cost-effectiveness in an embedded system. -- By K. Padmanabhan, P. Swaminathan & S. Ananthi

Method II. This message display program uses look-up table. In the message display program described in Method I, ‘Call lcdwr’ instruction was written for each character. Here, instead, if we enter all the bytes for ‘Electronics ForU’ in a table, they can be picked up one by one until the end and shown on the LCD screen. For the purpose, there is an instruction called load program memory (LPM).

The table, as also the name, is stored in the program memory. Here is the program along with necessary comments.

The actual-size PCB for programming and LCD message display are given in Figs 7 and 9, while their component layouts are shown in Figs 8 and 10, respectively.
