Christmas tree with smd leds controlled by PROCESSOR

Santer Claws

Bcoz I like computers ive been asked to build a tree with lights.

Anybody got an idea where i can start. What processor? What speed? How much memory?

    Any uC with enough pins so you don't have to multiplex the signals.

    Any speed is fast enough - we humans are quite slow :)

    Hardly any memory needed unless you want very complex light patterns.

    Do you have a commercial Keil licence? In that case, use such a processor.

    If not, go for a hole-mounted processor such a C51 processor with 40-pin DIP socket. That is easy to solder on a prototype board.

    Without a commercial license, the limit to the program size will not be the amount of memory in the chip, but the max application size supported by the free editions of the Keil tools.
