Hi Has any one had any experience with the L6470 Stepper Motor driver which uses an SPI interface (Sparkfun have a breakout board for it)? I have not used SPI at all, will be a whole new Picaxe adventure, the fact that the driver works autonomously after being told what to do my make up for a...

Hi Probably missing something very basic, I have downloaded and installed logicator and can create a simple flowchart and program the picaxe. My problem is that most of the commands are not available (greyed out). Do they need to be activated in some way? The "Basic" command is not available...

Hi I know that this problem has been dealt with a few time, but without any code snippets (that I could find). I am trying to read a shaft encoder on a motor which will control the taper tool movement on a lathe. The motor runs at 120 rpm with the encoder reading on a 30 tooth gear. I can...

Hi I'm having some difficulty with the Time variable which is supposed to give an accurate time per 1 second up to 65535 seconds. I am using a 20M2 chip with the following code main do debug loop while time < 5 gosub led goto main Led: time = 0 high c.7 pause...

Hi Has anyone done any research or experimentation on using a smartphone (iphone or android) as a display for a picaxe application using a bluetooth connection? Even a simple terminal type app on the smartphone which would allow display of serial data via bluetooth? I am interested in setting...

Hi Is it possible to use a 2803 to bi-directionally drive a small motor. eg. pin1 high providing negative and pin 2 low providing the positive. Pin1 low and pin2 high puts it into reverse. A bit of a play suggests that the 2803 does not provide a negative when driven high. The circuit is...

I have a 14M running a controller for opening a gate. I would like to use a ricoh camera infrared remote controller to activate the gate. The controller emits a single solid pulse of about 0.5 sec. Using readadc and activating when the value is less than 50 works well. However, I need to be able...

Hi Can anyone suggest an easy method of creating an inteval timer using the DS1307. I have problems with the BCD maths when adding a timing interval to the last alarm time. e.g. using only minutes, alarm timer 58 minutes add 17 min = 75 (dec) - 60 to get minutes = 15 min. In practice this...
