hello all,
 

Working on a project for an LED clock (not exactly rocket science - but fun) and I have questions on the selection of micro-processor - SX48 or Propeller.  6 x 8 segment LED's arrange in a 8 x 4 grid - so each 8 are pulsed at a time.  (see - pjv and Gunthers posts here - [url=http://forums.parallax.com/forums/default.aspx?f=7&m=162118]http://forums.parallax.com/forums/default.aspx?f=7&m=162118[/url]) 

 

The code has to refresh the clock digits rapidly to maintain persistance of vision and also wait for an input from a IR remote.  Can I do this using an SX48 timer and the ISR to watch for the IR remote?  I don't want to wait for the pulse on the ISR - I guess it would cause the clock display to hickup?

 

How easy is the SX48 to hand solder onto a PCB?  I can do the propeller Q44 SMT chip with care.

 

Kinda wanting this to be a SX project but leaning towards the Propeller for it now.

 

Thoughts?

 

Cheers,

 

James
