    Sending negative numbers (signed integer) using serial

    Hi I have been experimenting with a Robertsonics WAV Trigger for mixing audio tracks using the serial output from a Picaxe 08M2 to control it. robertsonics WAV Trigger I have been successful in controlling most functions on the such as Start / Stop / Pause / Resume / Loop tracks, however I am...

    Touch problem on 08M2

    Hello I am having some problems with Touch16 command on an 08M2 chip. I am using all the pins on the chip including pin c.5 as a digital input from an external switch. (I use the Disconnect command after the program starts to ensure pin c.5 works correctly). If the external switch is open and...

    SD21 Servo Position Feedback Errors

    Hippy - I think that you have correctly identified the problem. I am obtaining the position of the servo by reading the low byte followed immediately by the high byte. I have done a bit more work with the data in a spreadsheet and come up with the attached table which shows a typical error...

    SD21 Servo Position Feedback Errors

    Hi I am currently working on a project using an SD21 servo control board with a Picaxe 18M2. I am controlling a number of servos using the position and speed registers in a continuous cycle and using the SD21 servo feedback registers to trigger events when a servo reaches 80% of its stroke. I...

    Model Rowing Boat

    Thanks for all the comments - I am afraid that I don't work in TV (as you can probably tell from my focusing on the video) and I think it would take a long time to get to New Zealand because in anything other than a gently breeze it is one stroke forwards and then get blown backwards again! I...

    Model Rowing Boat

    Hi I thought I would just share a few pictures and video clips of my most recent Picaxe project. I have scratch built a model rowing boat complete with a rowing man using a modified Action Man toy. The body of the Action Man contains 4 servos to operate each arm, his back movement and his head...

    Random is not quite so Random?

    Hi, I have a project where I want to make a random decision to turn left or right using an 18M2 picaxe. My idea is to to use 'Random' to generate a random word variable and then compare the two associated byte variables. If the lower byte > higher byte then turn left else if the lower byte <...

    PWMOUT with AXE 023 Motor Driver

    Hello, I am looking at a project which uses an AXE023 motor driver board with 08M2 chip to drive a small motor in both directions. I would like to control the speed of the motor so I was going to use a PWMOUT and PWMDUTY, however I notice that the 08M2 only has one PWM pin available on pin c.2...

    Axe 027 Not Recognised

    I have been using my Axe027 USB download cable for several years without difficulties. Just recently I have started experiencing intermittent problems when plugging the USB cable in to my computer. Sometimes it is recognised by Windows and runs perfectly, on other occasions I plug it in but...

    AXE023 Voltage Decay Problem

    I am currently working on a project to control a small water pump using AXE023 Motor Driver Board. I have replaced the supplied Picaxe 08 with a new 08M2, and I am powering the board with a 3 volt supply (2 x 1.5V AA cells). I want to use input 3 (pin c.3 on the 08M2) to sense if an external 12...

    Automated Model Dredger

    Thought I would just share the project which I have been working on for the last 18 months with you. I originally built the model of the Mannin dredger about 8 years ago, with everything being operated via radio control. Unfortuantely sailing the model (controlling throttle & rudder) and...

    Servo with High / Low Pins

    I am using a Picaxe 18x to control a servo on output pin 0 using the Servo & Servpos commands. After I have sent a Servopos update I then want to change the status of several LED's on output pins 1 - 4. My code at the moment is using Servopos on pin 0 followed by multiple High / Low commands on...

    SD21 Servo Mid Position

    I am having a problem with the SD21 servo control board. When I power it up all the connected servos appear to default to their mid position. This is fine except two servos which I want to default to an end position. On power up these two servos move to their mid position first and then return...

    Interrupt and Return problem

    I have a program which is set up to operate in 2 x modes (I have called them auto & manual). In auto mode I have an interrupt set to jump to manual mode when pin 6 is high. The problem that I have is I don't want to resume in auto mode after the interrupt has completed - I just want to return to...
