  1. Re: Generate a non-blocking pulse with an Interrupt Service Routine

    I agree with Ioannis, generally, on the use of Pause, but using a loop of short pauses can be a bit of a work around. Rather than pausing for 1 full second, pausing for 1/10 of a second (in a For/...

    Re: Lcdout macro problem

    Working my way through your suggestions I discovered that the problem was this:

    I cut and pasted the clock code from another project and did not realize I'd used the byte variable REG_VAL[7] to...

    Re: Lcdout macro problem

    Thank you, gentlepeople, for the advice. I will correct as advised and report result. While I did find some information on "USERCOMMAND", which appears to be how LCDOUT was implemented, it seems far...

    Re: Lcdout macro problem

    Thanks for your time, Richard. Below is the full code.

    Lcdout macro problem

    So, there I was happily programming away... slowly putting together the attached menu tree and suddenly, between one compile and the next, this error shows up: Macro LCDOUTSTR?W not found in macro...
  6. Re: Getting data from user, how to store it properly? (kinda dialog interface)

    I'm wondering if it may be beneficial to restrict the project to chips with EEPROM? It seems somewhat tedious to enter all those numbers... and then lose them with a loss of power - intentional or...

    Re: HTML and PIC communication

    So it appears that the MCU [Arduino] maintains an array, sending and receiving elements serially. It looks as though the PC portion is worked out (other than the USB). I'm guessing here, but is it...

    That, my friend, is awesome!

    I have an aquarium controller project (2.0) that is paused for just such an interface - my interest was not altogether altruistic. Please elaborate on "Involt" is this...

    It's not a particularly "user friendly" tool. I typically begin with a couple must have attributes and filter on those, then sort on some of my secondary requirements. Finally, order 3 - 2 of which...

    Re: HTML and PIC communication

    Yes, I'm sorry that it is not so easy, from there.

    I think it may be necessary to visit forums for programming - depending on your operating system. The crux of your issue is the "bridge" program...

    Re: ADC input signal filter selection

    Hi Mark, welcome to the forum.

    I'm a hobbyist (the hobbiest of hobbyists) and struggle similarly. I have come to the conclusion that I can spend time trying to quantify the noise - so as to know...

    Re: Converting dec to hex, no built-in support?

    I'm not sure what you mean. You do not convert to HEX, you represent in hex. Consider: In your clock example the value is "12". You might represent that in 10 based decimal as "12" or, you might...

  17. Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

    If you can " light up any digits via any pins in software", it is unlikely to be the configuration. More likely in my mind the I2C routines to retrieve clock data. Can you get Hour and Minute values...

    Adafruit 12 key touchpad

    I'm trying to get an Adafruit 12 key capacitive touchpad (https://www.adafruit.com/product/1982) going. I don't think I'm too far off, but the multiple registers, Arduino-centric tutorial, and my own...
  19. Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

    I looked at it and, frankly, suggest that:

    Code you write (and understand) is far more maintainable, and therefore "better" than code someone else writes that cannot be modified later. The...
  20. Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

    If DIG0 is "ones" digit of minutes, and DIG1 is "tens" digit, then:

    READ [MINUTEVALUE + 1], WORD WordVar
    PORTC = WordVar.lowbyte
    PORTD = WordVar.HighByte

    In fact, you could then:

  21. Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

    If you are building a clock, the minutes digits never exceed 60 - you require 10 digits for the "ones" (0 - 9), but only 6 for the "tens" (0 - 5). So, it will be possible to map every possible minute...

    Hitachi vs Sitronix LCD

    I recently purchased several of these: https://focuslcds.com/product/8x1-stn-character-lcd-c81bxbsbsw6wf55xaa. They are a simple (or so I thought) 8 character LCD. I have, and use, 4 line Hitachi...
  24. Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

    I typically use DATA statements (simple with internal EEPROM) to map each 7 segment character in a byte value. 'A' segment is least significant digit, 'G' segment is bit 6. Bit 7 is unused. For...
