I made a program that is essentially a clock and I use a Pic16F84a. At fixed intervals of time the program call one of tree possible messages from a table made with the "DT" directive. Al goes well with the fist two messages but when third message is called the program is resetted and count begins again from zero. If I in the third message I use two character less all run well. All messages have a maximum of 5 characters and total program memory used is 253 words. What could be wrong? Thanks Renzo -- Internal Virus Database is out-of-date. Checked by AVG Anti-Virus.
