    PIC and 44780 LCD

    thanks\1 Yea, I think I had problems with initializing the ports that was the thing. I got it fixed now. Alright, I looked over the coding you have and the one on the piclist site is very similar to it. As with the code that comes with the hitech compiler. The piclist code (craig lee's) is...

    PIC and 44780 LCD

    Hi, I'm using a 16f877, hitech C and (i think) a 44780 compatible LCD. I just want to get some basic text writing on the LCD going, but I can't even seem to do that. I am using the example code that came with the hitech compiler but with my own delay function, because that one was giving...

    16f877 help with config word

    Hi, I am using fpp to program a 16f877 using the Trivial Low voltage programmer. Does anyone know why I might be getting a "failure to write config" error message? This may seem like a basic question but I haven't seen any solutions to this. I can read and write fine, but it is always the...

    74HCTLS573

    no thanks. I tHINK this thing works... the HCTLS works just like an HCT except it is "bipolar"...

    74HCTLS573

    Hi, I couldn't find any datasheets for this part. What does this do? I need a 74HCT573, is this the same? I have both teh LS and the HC version, as well as the HCTLS version. but I don't have just an HCT version. Can i use this in my programmer?

    bc557 substitution

    Hi, I am making a programmer for a PIC and it calls for a bc557. does anyone know any north american equivalent of this transistor?

    Multi-Pulse Sequencer using 555s

    Well, after trying my circuit and reading at all your replies, I've come to the conclusion that the thing I have right now is the only thing that can allow me to adjust each time individually and not have overlapping sequences (If I adjust the time too long on the 4017 circuit this happens)...

    Multi-Pulse Sequencer using 555s

    Sorry, I didn't make entirely clear exactly what I want... I need to be able to adjust the timing intervals on the fly (as it's running). Basically what I am making is a timing device used to replace button presses for various parts of a person's gait cycle. I must be able to tailor the times...

    Multi-Pulse Sequencer using 555s

    Hi all, Basically, I need to make a series of pulses in continuos operation, five of them, with variable timing in between them. These pulses will be used in an electric stimulator (for physiotherapy) to act as push button presses. I've already created a "daisy-chained" circuit of monostable...
