    User-Programmable Timer

    I did this project to control a water heater. It has two schedules with two timing phases in each. A weekday schedule and weekend schedule can be programmed. The schedules are programmable by the end-user. The code can be altered to provide for individual schedules for each day of the week or...

    Im tinkering with i2c. I wrote a small program just for testing. It reads adc0 and stores its value in b0, then stores b0 at b1 on my i2cslave(24LC16B). I then try to use readi2c to read the value from the eeprom and display it on my lcd readout. main: readadc 0,b0 i2cslave %10100000, i2cslow...

    Shift decimal in variable?

    Im reading voltage from a small solar panel. VOC is 25.6V. Im using a voltage divider to get it down to 5v. With a 10K on top and 2.4K on bottom, I get 4.95xxxV(close enough for my purposes). Because of my highest voltage being 25.6 my adc values are exact multiples of the actual voltages by...

    The ADC Keypad

    Hello gents Some of you had been following the progress of the 'one input keypad'. Im here to say weve come to a great working solution. The circuit is so easy to build and adapt to different numbers of switches. The code, well the code is ridiculously easy. <A...

    Correct use of write command?

    IM trying to change 4 numbers in my eeprom on a 40x1. The app is to change a pin number. I save the numbers 1,2,3,4 initially using the EEPROM 90,(1,2,3,4) instruction then go into the main loop. When its time to change it, I use this: write b3,90 write b4,91 write b5,92 write b6,93 The...

    One input keypad?

    I got this idea from a post I had come across on this forum. I wasnt able to find the post again in the archives, neither was I able to find anything about anyone pursuing the concept. I decided to give it a whirl and this is what Ive come up with so far. I am...

    debug and functionality problem

    When I download my program to a 40x1 without a debug command, it does not work. If I out a debug command in it anywhere, it works perfectly. Can anyone explain this. Also, when working with the programming editor, after 2-3 downloads it stops connecting to the picaxe. I have to restart the...

    Hi, Im fairly new to the picaxe and the programming world in general. Ive been tinkering around with a 14M and have run in to a minor problem I cant see to get a leg over. I d appreciate any help. I wrote a very simple little program, counts # of pulses over 5 sec and display the PPM and COUNT...
