    Getting Data from Adafruit Ultimate GPS V3 onto 28x2 Picaxe

    Hi ChrisN141, for some ideas perhaps look at SKYLAB SKM53 GPS or NEO7 and the AXE133 | PICAXE Forum to convert using a high word try knots to mph *2**37709 knots to kmph *2**60687

    Getting Data from Adafruit Ultimate GPS V3 onto 28x2 Picaxe

    Hi ChrisN141, I guess the first step is to try if can receive data ok. This program should sertxd your gprmc sentence from the picaxe. At the end the checksum is displayed in decimal it is usually hex the conversion is required to check that it is correct. You can also check what the actual...

    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 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...

    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

    lcd question with 18m2

    Hi Klaasje, you probaly will require at least a 200uf cap to hold up your oled 1602 display it can be trickly to save variables with the supply collapsing I assumed you are using a 5v regulated supply a better method may be to seperate the supply to the 18m2 with a diode and its own decouplin...
