    Are Rev-Ed & Picaxe missing out??

    I'm using RF24L01 modules, background receive on SPI bus

    Surely a PICAXE could be shoehorned in somewhere

    The idea was to picaxe-ify the projects, the models are there, how you drive them is down to you. One of the barriers to doing things is not having the models. You can pick up a reasonable printer for about £120 and give yourself access to as many or as few as you like, either pre designed or...

    Surely a PICAXE could be shoehorned in somewhere

    buy a 3D printer, unlimited projects right there. The sort of kits are great for kids, but i suspect you already have a parts collection of things like switches, motors and LEDs. There are plenty of sites to get models from, print them, apply picaxe and off you go examples: EEZYbotARM MK2 by...

    Are Rev-Ed & Picaxe missing out??

    the upside C-like variables though is you are not restricted to however many variables have been designed into the system. I can have, within reason and withing the confines of dysnamic memory as many as i like. Current project uses 37 byte varibales and 6 int (think word variables) varaibles...

    Are Rev-Ed & Picaxe missing out??

    they can be a little funny i find, tell you somemthing with no explanation behind it which is frustrating as all hell when your trying to learn. All the code for the librarys are in the librarys folder, they are not easy to interpret though. Think of it like this, its the same as using an I2C or...

    Are Rev-Ed & Picaxe missing out??

    That is the problem you see, everyone want the latest and greatest but refuse to move with it. Arguably it was one of the issues that AMD created for themselves in the past, keeping legacy instruction sets and the likes going. The same happened when vista was released, I had 2 year old machine...

    Are Rev-Ed & Picaxe missing out??

    That is true. But honestly I went from picaxe to Arduino C and find there to be very little difference in most commands. The main difference IMHO is the way it is presented, even just the type face that is used can make C feel daunting by comparison. Then there is the forgetting that darn...

    Are Rev-Ed & Picaxe missing out??

    The unfortunate thing is, if you know C and can optimise it even a little using basic is kind of pointless. The open source 3D printer firmware, marlin (or GRBL), is written in C, I can't get a over clocked 28x2 to run any wear near fast enough to match it's speed while it's running on an Arduino.

    Low Freq PWM and Interrupts

    I was thinking you could take the section where the astable 555 could be adjusted using a digital pot. Dispence with the rest of it and you have a PWM signal that can adjusted down as low as you like. But I must agree using a 08m is a good solution too, and will be alot flexible, you could use...

    Low Freq PWM and Interrupts

    funny you memntion the 555, not really related but still interseting and you maybe able to take something away and apply it here (came across while randomly consuming random internet videos) I2C Enabled 555 Noise Maker Controlled by Arduino Uno - YouTube Using a digital potentiometer to vary the...

    Creating a map subroutine

    thanks for testing that> I did have a look around for something similar, but evidentially not well enough. Both cases should work with PWM as well which is nice.

    Creating a map subroutine

    I have done a little more workon this, cut the variable down to 2 and just 2 lines of code in a subroutine. You mamybe able to make it into a macro as its quite small. I dont have a servo to test this with, simulation seems to show it works, but would br grateful if somemone could test it...

    Creating a map subroutine

    I have been doing a fair bit of C programming, and using the map function, somemthing that is missing from the picaxe system. So i thought it will work in interger maths and breaking ti down into its seperate parts to correct for order of operations should allow it to work on the picaxe. Well it...

    Controlling stepper motor

    OK, where to start. You can find the data sheet for the actual driver IC here: TB67S269FTG | Stepping Motor Driver ICs | Toshiba Electronic Devices & Storage Corporation | Asia-English (semicon-storage.com) Next, drop the picaxe. I assume the the "torque" setting is actually v-ref, and there...

    Any new chips? More RAM? Faster Clock?

    I haven't checked the PIC product line of late, but wonder if there is actually a big enough step up to make picaxe development worth while. There are other systems that what you want and more, the downside is they are not picaxe. Pjrc have some pretty awesome bits of kit but could be thought of...
