    My Pot Position LED patterns not quite right ????

    Hi OLDmarty position 0 plus position 20 = 21 so (21 x 65536 / 255 ) = 5397 so try Pot_Position=Pot_Position **5397

    Adding a DS18B20 to axe132 board

    now some code to test ... will display Celsius temperature with minimum and maximum cycling evry 15secs on line 2 of an OLED display. If switch is pressed on release will swap to Fahrenheit . If switch is held it will eventually display (reset) release min/max will start again. #picaxe 18m2...

    Supplied drivers do not work with many Windows 11 machines

    pid 6001 always self updated on my windows 10 pc so it may depend on which version you have. pid bd90 is now supported I just tried a w10 pc plugged the axe027 and the drivers updated to the latest version if I didnt look in device manager I would have never known.

    Supplied drivers do not work with many Windows 11 machines

    Just newly installed w11pro on my newish home PC🙃 loaded PE 6.1.0.0 which hasn't changed. all ok! tried ch340g serial loads quickly and seamlessly. Thought I'd try the picaxe027 cable looking at Device Manager using the PE editor. It didn't appear at first but soon seamlessly self-installed...

    Picaxe programmer PCB for CH340 "Gold" USB Serial Adapter

    Hi NigelT, I myself like the idea of having a project completely isolated. from anything I connect like a pc or a laptop which can be pricey these days. The actual optoisolator used is a SFH610A-2 the transfer ratio can vary between models. It happened to be some I had, so the resistor values...

    PICAXE 014M and LCD AXE133Y

    For some 4.5v supply is too low to drive the logic controller of the LCD it Vary's slightly with temperature which may explain why it works sometimes. A 5.0v regulated supply is typically recommended.

    Determine resistor value

    Hi regpye, Its common to terminate an ADCpin with a 10K ohm resistor to ground. so R2 is always 10K usually each position will switch its own series resistor from V+ picaxe supply to the common adcpin. sw.pos ADCvalue nearestR1 1 150 56K 2 250...

    PICAXE module boards, tell me what you think.

    hi harolds1956, I just finished making a new project board easy to plug in a 8m2 14m2 20m2 20x2 at the moment only power is conected to the top two socket pins the required serin pulldown 15k is on the optoboard if i need to test a 18m2 i can just drop down a slot and carefully connect to the...

    LCD initialising problem

    hi mickm2au, I just finished making a new project board. I have a 14m2 so writing some code for a lcd will be a good test for it! It's a pity the 14m2 remaps its ports it could have been a little quicker. a sneaky rewrite of initialization so we don't need to include some pauses. from memory...

    Error Installing Drivers

    probably the best solution to change the pid as suggested by kfjl back in post#11 I've avoided reprograming my cable in the past as I have never needed to do so. If you have your axe027 working on the desktop its quite easy to change the pid using the REV Ed programing tool AXE027 Programming...

    Understanding 20X2 interrupts

    Hi micrometal, that is proberly correct The setint command causes a polled interrupt on a certain input pin conditions. This can be a combination of pins on the default input port The default condition is a logical AND of the selected input pins. try setintflags OR %00000110, %00000110
