AI is a good tool in the hands of people who can do without it. Robot translators are too. Both save a lot of time and typing. In the hands of people who can't do without it, you end up with something like this:

Hi, My PCF8574-I2C-backpacked LCD also works without adding pullup resistors, so they must be on the board. Mine is very fussy about good connections.

Hi, From what I've read, you can't start off with a Chromebook. You need a Windows computer to install the cable with its Picaxe pid and then use the Axe 027 programming tool to change the pid to its default value of 6001. https://picaxe.com/docs/axe027.pdf If you install the Picaxe...

Hi, All your questions are answered on the page you link to. axe027-programming-tool is a watered-down version of FTDI-prog that won't let you do anything to destroy your axe027, so you can try it with no risk. I used FTDI-prog to change the PID and invert the RX and TX signals so I could use...

dgc188's problem wasn't with simulation.

Hi, Maybe you're looking at 4FSK and trying to make sense of it as if it were 2FSK. I didn't know what FSK is so I looked it up and came across THIS page.

Nially :) That would have been my first step. Program an emitter to send 1 to 10 in a loop and power it off a couple of 1.5V batteries. Then program a receiver to catch what the emitter sends and show it in the terminal. Then, lower the baud rates to something a 08M2 is comfortable with and...

The factory settings put the baud rate at 115200, so you might need a faster chip to send the first AT commands to slow it down enough for a picaxe. You'll need to run a picaxe on 3.3V or use a voltage adapter. Putting two modules too close together can damage them. I don't know exactly how...

A bit more usefull: AT commands

Hi, Try DuckDuckGo. PDF

What else?

The USB cable works. I did a 5 minute print of an M4 wingnut with no trouble. I'll do progressively bigger print jobs, watching for any overheating. @Buzby: Processing looks like the best bet for making a GUI.

Hi, Thanks for the reply. Yes, I use the same model. What a daft place to put the card-reader! I was thinking of an sd card extender to bring the reader out front. It seems files can be transferred between a laptop's USB3 port and the printer's USB C port. I'll give it a try if I can get my...

That's an impressive layout! Chat GPT isn't cheating, it's a way of getting things done. I don't like it because it takes the fun out of programming. It's like filling in a crossword puzzle from the solution. I put the sd card into my laptop to copy the gcode files and then put it back...

My bad. I'll mop up. :) The blogs archive is just above the sandbox, but I wouldn't bother with the wireless stuff. I'd forgotten you're only 10 meters or so from the circuit. Try a cable as Buzby suggested.

Three or four decades ago I worked as a pipe-fitter/welder/sheet-metal worker, a lot of the time in industrial food factories. That's where I saw the sensors. At the time, all I needed to know about sensors was to keep the welder's ground-clamp as near as possible to what I was welding so I...

Hi, GAP, I think the best idea so far is yours : "delusions of grandeur". Collect the information using Buzby's yoghurt-proof, squirting sausage meat-proof, door-opening sensors (I've seen them work), in a picaxe near your railway and send them by wifi, LoRa, NRF24, bluetooth, or whatever, to...

Try getting rid of this line: If val < 50 then pwmduty C.1, 239

Your program works for me: #picaxe 08m2 #no_data symbol speed_control = C.4 symbol val = w0 ; word (16-bit) user variable symbol pwmPin = C.2 init: pwmout pwmPin, 199, 399 main: readadc10 speed_control, val ; read 10-bit ADC into variable w0 pwmduty pwmPin, val ; set pwm duty goto main...

Hi, I've never used a keypad, but I noticed what looks like a "cut-and-paste" error: low col3 ;Turn OFF Column 1. low col3 ;Turn OFF Column 2. high col3 ;Ready to read Keypress on 3,6,9 or "#". Anyway, I think you should be writing to the...
