  1. You disapoint me , Id rather you print "07734" on some inverted Nixie tubes. Hey Picxie, I geddit!! for the sake of a good joke, I shall of course let it pass that "normal" nixie tubes are not seven segment devices. I am currently writing the application software for these nixie clocks in assembler. But I thought it time to move up a gear, so to speak. I ultimately probably wont need a printf() command at all, as I will still speak to the nixie tubes via direct port control. But I needed a half-way house, so that I could "see" if my early code was doing what I had intended it do.
  2. Hi Dave, it's not so much the formatting of output that had me stumped, but more where the output comes out by default! Followinf on from the above replies and some more digging, I begin to see the light. I will try a vanilla flavoured LCD interface and see if I can get it to display "hello world" Thanks for your response anyway
  3. Matt and Ragi; thanks both for your continued input on this. I'm learning all the time Laurence
  4. Raghunathan, thanks for your reply. The penny begins to drop! My next question was going to be "what is the LCD wiring?", but reading through LCD.H I think I can see what's going on. I'll start with an LCD interface first, then see if i can get a serial one running later. I'm going to have to be careful though, as my software is pretty time-critical, and it can't spend a lot of time "hanging about" waiting for serial data to be output! Most of my current assembly routines use interrupts. Once I get really clever, I guess I could build an interupt driven serial output. Best to learn to cra
  5. Guys, I am sure this is real "page 1" stuff! I am a complete C newbie, having cut my teeth more moons ago than I care to remember on FORTRAN (yes, I am THAT old) and Borland Pascal. I have also written a number of PIC programs in assembler. Fast, tight code, I get exactly what I want, but by golly does it take a long to time get it right! For my next project, I've decide to make the leap to C, and BoostC in particular. It's printf() that's got me stumped. I can see how the command works, just not where it comes out! My application may have an output device, but it sure wont be standard, an
