    NOT command

    This may be a silly question.. Is there a way to express NOT > value or NOT < value? I'm aware of <> or != the value. However, I couldn't find a variation for - NOT greater than or NOT less than the value. My application (M2) requires a NOT, due to ADC read fluctuations that can't be overcome...

    Electronically controlled water tank inlet flush unit

    Hi again guys, This is a project that I made a few years back. I actually have 2 of them operating on two tanks. The main disadvantage with a standard Water Tank 'First Flush', is that they don't get rid of enough debris from the water collection point and the organic matter that builds in...

    Portable battery driven water pump

    Hi guys. This is a project I made to use for watering the Garden and Tree's through the drought we had recently. It made it much easier than running tens or hundreds of meters of hose from the main water line. While I do have a few small tanks around the property. I thought it might give an idea...

    X2 vs M2 Pause times

    I have run a certain program with a 14M2 for long while. And today I load it to a 28X2. The specific part of the code that I noticed the change was a Flashing sequence, that included PAUSE's. Its the same code with the same clock speed, M16. But the flashing sequence on the X2, is at half the...

    Midas vs Winstar 16x2 OLED

    I'm considering getting another 16x2 OLED display. So I download the specs of the Midas units. They appear to have some nice functions compared to Winstar. Like... smooth horizontal scrolling and line shift selection. Have any of you guys used one of these? To confirm that they will do these...

    RTC with 2/3 day lenght time

    This is the first half a project that I started working on a month ago. Although it still works as a free standing unit at this point. The other part will be external with sensors. Plus I wanted to say a thanks to all you guys that have help me along the way, with many posts and snippets that I...

    Bptr Symbol and S_W variable questions

    I'm wondering if there is a way to give a Bit Pointer locations a Symbol? The example below doesn't check out. But I was wondering if there is a way to do it, that I have missed. Symbol TEST = bptr = 50 Main: If @TEST = 1 then : Goto stuff Endif And also wondering if a Special Word variable...

    Displaying Letters via lookup command

    Hi guys, I there a way to display Letters, when using lookup / pulsout. Rather than using a Serout command? I know of using - serout OLED, baud,(254,131,"",#hour,":",#minute,":",#second,"AM") But what I am wondering. Is there a way to place a Letter in the lookup...

    20X2 vs M2 memory and slots

    The 20X2 only has one program slot. With 4096b in that slot. While the M2's also have a total of 4096b, in 2 slots. With 2048 bytes in each. I have had a few times when 2048bytes of memory on M2's, isn't enough. And using the second slot is somewhat inconvenient, because of the extra...

    Reset variables when changing SLOT

    Is it a reasonable practice to Reset variables on a SLOT before the new slot is entered? I am using a 14M2 and want to use slot 0 and slot 1 as independent programs. Because of the way the change between the two takes place (on power up not power down), it isn't easy to do a reset before it...

    AXE131Y 8x2 OLED 18M2 custom firmware

    To start with. The 18M2 on the OLED driver board does the job. But only in a simple way. I have found the basic commands rather lacking. In the way, that if you want the display to scroll, it scrolls both lines. Rather than just being able to scroll the top or just the bottom line. While...

    Download errors

    Hi people, I have been having trouble of late with a program that I have upgraded. And have refined it quite a bit; plus also changed the hardware as well. I have been left chasing my tail for the last week with this. One of the new features I added, was a motor driver with a current shunt...

    Re-enabling an interrupt outside the setint subroutine

    The title says it. The manual says it has to be done in the interrupt sub. But is there a way around doing it somewhere else in the program? My reason being. Is that I don't what the interrupt to be continuously triggered, until an input state of its pin changes within the program. Then I...

    Using and output to power an 08M2

    Over the last year, I have increasingly found the need to run parallel picaxe's. In this current project. I am using a Hall sensor, like a rotary encoder. The problem I am having here, is the same as I often have. Not enough processor time to run everything else and count pulses from the hall...

    M3 or X3 series

    I know this has more than likely been asked somewhere else before. Is Rev Ed working on another Picaxe release. i.e. An M3 or X3 series? I do understand that this is all dependent on the hardware available to do the work. It would just be great if Picaxe had 12bit or > resolution...

    Designing all in one PCB (wish list)

    Hi guys, I have designed a few PCB's over the years for Picaxe's. And there have worked out fine, but have been based around single chips. I have been considering designing a new board for a while, that would have two Picaxe's. For the purpose of having totally independent processing. So that...

    ERF module sleep mode

    Hi all, After looking through this forum for an answer. Most of what I have found to this question is dead links. Now that Ciseco aren't around anymore. I still use many ERF modules. But have found the power consumption awful. Even while using the CTS pin. Which I initially thought...

    Select/Case not working correctly

    Hi all, I often use SELECT/CASE over IF/ENDIF. But in a few situations when the select/case has more complex items to handle. I have found that it seems to get bogged down more then a conventional If/Endif format. To the point that it will refuse to work at all. Even though it checks out fine...

    Comm issue with 14M2 chip

    Hi all, I have one specific 14M2 that requires a hard reset, almost every time I commence an upload to it. If I just hit program, it come up with a comm port error, 8 of 10 times. I thought it may have been the cable interface or the drivers. But I have checked all that over and its all good...

    Writing to eeprom on loss of power

    What i am trying to accomplish is, writing data to the eeprom at the point of a power loss. I could just have it write to the eeprom every few seconds, so the program knows where it was on power-up. But this is just wearing out the eeprom. I thought of using a flag-interrupt to measure a voltage...
