Hi there. I'm using PE version 5.3.0 under Windows 7 x64. I'm trying to download some code to an 18X. The code contains the line pause 4000 At the start. When trying to compile, simulate or syntax check, it highlights the above line and comes up with the following error: 'pause 2000 Error...

Does anyone know how to get StampPlot Lite or Pro to plot values from a file instead of from the serial port? Not technically a Picaxe question, I know, but I plan to use it in conjunction with a Picaxe. I have some maths to do which will be a bit complicated to work out how to do on the...

Hi there I am using the HP03S sensor in a circuit for a weather station. I have read all of the calibration values successfully. My values are within the ranges specified by WestAust55's pdf on this matter. I am using his code to read the raw temperature and pressure readings now. I am having...

Hi I'm trying to read the i2c values from the HH10D and I am having some trouble. If I read from location 10, then I get: 1 114 29 205 I am unsure what to do next. According to the Silicon Chip article (using my values): Sens = 1 * 256 + 114 = 370 Offset = 29 * 256 + 205 = 7629 These values...

Hi there I have a few questions about Picaxes in general. 1. Some of the parts have letters (08M, 28A, 18X). Do these letters stand for anything? 2. I've seen an input pin referred to as "high impedance". Is this high impedance to Vcc or ground? 3. Related to question 2, I have some LEDs...

Is this circuit likely to work? My reasoning for the resistor is to limit the panel's maximum of 400mA to about 100mA to charge the 1000mAH batteries., and the zener is to limit the voltage to around 4.3 volts, because I suspect that anything less than around 4 volts wouldn't charge the...

I wish to purchase this sensor: http://www.futurlec.com/HP03D.shtml It requires a 32k crystal. Is there a Picaxe command I can use (I am using 20X2) that will allow me to connect a picaxe pin to the crystal pin to replace the crystal? In other words, can I generate a 32k signal instead of...

So, I have a project where my Picaxe needs to run from 3 NiMH batteries, so 3.6 volts. I need to use the DS1307 with this project, but the clock unfortunately only runs between 4.5 and 5.5 volts. Anything lower and the backup battery automatically kicks in and you can't read or write to the...

G'day there Here's a circuit I made a while ago. I had read on the internet that certain mobile phones could be used as a remote control for your computer. My old phone wasn't one of these, so I thought: why don't I build something to do this? My camera wouldn't take a good enough photo of the...

G'day all I am trying to decide whether to use a 3.3 volt or 5 volt Axe for a project. I had a few questions about the differences: Does the 3.3 volt require less current compared to the 5 volt if they are performing the same tasks? Can the 3.3 volt Axes still supply ~20 mA on a pin?

For my school project next year (the teacher has advised us to think about our designs and such now), I want to build a weather station type thing. One requirement is that our projects must be powered by renewable energy. I thought it would be easiest to use a solar panel. So, I decided that I...

Hello everyone I have the DS18B20 sensor and I made a little temperature logging doohickey; that uses an RTC and the temp sensor to log the temperature every minute. I had an option to display the temperature in Fahrenheit. My code goes like this: readtemp 2, Celsius pause 750 Fahrenheit =...

Ok, so I wanted to make an ohm meter with the readadc command. I have some code, but it returns values that aren't expected. Here is my code: It's entirely possible that my calculations are completely wrong; I probably need another person to look at my code. Thanks in advance. PS my circuit...

Hi I have the Picaxe 18X and want to use an RTC plus an EEPROM chip. I couldn't find any mention to multiple i2c devices in the manuals. Then I found some code which simply used the i2cslave command again whenever it wanted to talk to a different device. Is this how I would do it? To put it...

I bought the DS1307 mini board from Futurlec. I have been using the DS1307.bas from the samples folder in the Porgramming Editor. I modified it so instead of outputting to an LCD, it outputs to the Terminal (sertxd). I am receiving weird numbers, like this: The date part is good, except the...

Hello I have the Picaxe 18-X chip and I am using it to read data from a computer keyboard and print it to an LCD. I need a way to store each letter in memory, so I can make it so you type "run" or something and it runs another part of the program. I assume I would use the EEPROM command but I...

How come the 18M can do SERRXD but the 18X can't? I thought the 18X was the newer chip. Or is it a different reason?

Has anyone ever built something like this: http://www.botkin.org/dale/rs232_interface.htm If so, does it work with Picaxes?

Is is possible to have a chip that could read information from an IDE CD-ROM drive and communicate to a Picaxe through i2C?
