I have a problem here, which I hope you guys can help me
with. I need three things:
1) a 7segment displays(3 or 4)/decoder/driver - this
driver needs to have an 8bit(for a number up to 256, hence the 3
displays) input. driver needs to convert these 8 bits
into the corresponding digits(up to 3) and output them on the
displays. The driver can be a multiplexer, or an equivalent.
2) a programmable countdown/timer(must be programmable
with 8 bits).
3) a countup/timer with 8 bit output(to drive the
multiplexer or equivalent above.)
Thank you, any information(sources, chips, etc.) would be grateful.
