The picaxe is a great hobby platform, but what is needed is a user interface for projects that go beyond OLED type screens. This would be canned code that runs on PC or Mac or android. This would seem to be pretty simple, communicating via serial port on USB. Even a terminal program would be...

It would be possible to communicate via light sequences of pulses - What I am interested in is is to have 4 receivers, and a receiver "knows" what its unique pattern is. This is similar to a remote TV control, and as well spread spectrum algorithms. Has anyone implemented this in a Picaxe? I am...

Im sure this has been discussed before, but what is a good pot (10k) too use for Picaxe ADC (18m2 or similar)? -wirewound? -brand? -carbon OK? -attach noise filters to (caps to ground.) The history of this is I used a generic carbon pot on an ADC input, and it was a good random number...

Hello I am just checking to see if I need X2 series to do this. I want to have an int routine which measures intervals between pulses of an optical encoder. This interval will then determine the timing variable of a main loop for a stepper motor. This is for adapting an old lathe (1944 Logan) to...

Greetings I am trying to use a picaxe to control a stepper that does circle shapes. At each trace point, the engraver will move on the tangent of the circle for a short distance, then recalculate. For instance The first derivative of a circle is y' = +/- x/sqrt (25-x^2) This is a circle x^2...

I am attempting to copy Peter's project. (thermocouple made easy thread) So far so good. About the use of remote IR temperature sensors, although my main experience is with thermocouples, they are very useful for checking remote temperatures of reactors and machine hot spots. My low cost hand...

An open question: I tried to make a voltage divider with an ebay pot, but it was too noisy for a stable reading. The ADC value bounced around. Yes, I know, a cheap pot, and there will no doubt be the "Ford vs. Chevy" posts about the best pots. But I'd rather it were NOT dependent on the pot, or...

ISTM that the picaxe developer may occasionally want to field a picaxe app and be able to access the chip properties from a PC-type interface. For instance, manually changing a timing property, temperature limit, etc. Is there a "canned" way to do this? Serial ports are out, since PC's don't...

For a super-aquarium project, I want to dim power leds and pumps via a pwm output. I'd like to have 6 mosfet-controlled voltages 9-12 VDC. Here is what I assume: 1. pwm only useful pin output for this, hpwm not useful. (?) 2. 20m2 seems to have the most pwm's - 4 of 'em. 3. bit-banging a...

I'm posting this question as my results with the readadc10 on the 08M2 have been variable. In my circuit, I was measuring a voltage divider between a 5k pot and a 5k thermistor. When I turned the pot, the displayed value in debug did not change or it went to a random value. Rather than...

I looked through earlier posts, and there doesn't seem to be simple code to accumulate to a 32 bit total. I am working with sensor inputs and need to add many of them. SO - The way this is done, classicly, is to mask and shift carry bits along. And this can be done with operations on the X2...

Ive been building a glass blowing lathe. This kind of lathe has a head stock and tail stock that turn in unison to rotate the glass. My scheme has been to wrap an encoder strip around the HS chuck and read it with a photocell. I am using a neat little IC with a photodiode and transimpedance...
