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
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...
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.

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.
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...
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...
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.
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.

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...
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...
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

Hi j.mayer
sorry to see you're not having much joy! looking at the events log may help unfortunately, i can only show a successful one.
looks like the surface pro may have device security preventing successful install.
