    Chrome extension Picaxe Blockly 'no ports available'

    Hi I'm trying to use Chrome extension Picaxe Blockly, but there are no ports available when I have the AXE027 plugged in. Can you help please?

    Modifying a PWM signal - Hacking a RC car!

    Hi I'm using the formulae from the manual. Column H shows the duty cycle: Is a 50% duty cycle this: pwmout,128,156?

    Modifying a PWM signal - Hacking a RC car!

    OK - can anyone help with this? I have used the formula in the manual to calculate the length of time for the period and duty cycle using the default 4MHz speed: (I've posted it as an image because I can't seem to paste a table). Questions: Have I got the formula correct? Are columns F and H...

    08M2 Parallel processing help needed

    Thanks :giggle: I'm sorry for the confusion. My original code intended to light an LED on C1 using start1, whilst start0 monitored C3 for input before turning off C1 and turning on C2. Releasing the input C3 would reverse the process. However, it didn't seem to work. :cry: start0: do if...

    08M2 Parallel processing help needed

    So, parallel tasks can't override each other? I was hoping to use code0 to flash a light sequence, and code1 to monitor a button press, which then affects code0.

    08M2 Parallel processing help needed

    Ah! "different tasks" :eek::D I think that's helped - thanks.

    08M2 Parallel processing help needed

    Sorry for still not understanding. I don't really mind what the circuit does, I'm just trying to get a parallel program running! I can't find any examples of code anywhere that I can look at. Thanks again.

    08M2 Parallel processing help needed

    Thanks for the help! As I understand it, Start1 puts C1 high = red light on. Start0 checks for the input C3 (push switch), which makes C1 low (red off) and C2 high (green on). I can understand that Start1 will counteract Start0 - sorry if it's obvious, but how do I get this to work? Are there...

    08M2 Parallel processing help needed

    Hi - I'm trying to get some parallel processing going, but struggling. Any help appreciated! C3 is a PTM switch, C1 and C2 are LEDs. The circuit works with a single program - am I doing something wrong here? start0: do if pinC.3 = 1 then low C.1 high C.2 endif...

    Modifying a PWM signal - Hacking a RC car!

    News update: I have had some success by using a couple of solid state relays, at the back end of the car's motor driver, chopping the current further. Some period/duty combos seem to slow the motor speed! :D But trying to change that slow speed doesn't seem to do much. - What is the resonator...

    Modifying a PWM signal - Hacking a RC car!

    Hi, I am trying to reduce the speed of a RC car. It's a cheap chinese one, and I think it uses one of these http://www.ti.com/lit/ds/symlink/drv8833.pdf to drive the motors. Is there a way of somehow taking the PWM output from the above motor controller chip and reducing the duty cycle? Any...

    Remote Control Car application query

    Hi Picaxe, I wish to use Picaxe to remote control a car. I wish to create a new controller, and there are several motors on board (please see diagram) I need to use a module to transmit the signal to the car. As you can see from the diagram, Rotary switch 1 operates motors 1 - 4...

    Another Picaxe Stopwatch

    Blockly Wrestling Does the Blockly Simulation run at the speed that a Picaxe will run it? In the enclosed image of a program, I have done a loop that I hope will flick around watching the triggers (D2 & 3) to note if they full start. I can tweak the value 3000 to suit, however in the simulation...

    Another Picaxe Stopwatch

    Yes of course, I missed the zip option. This is the first part of the program. My son has studied coding and his advice is to start small with something that works on the simulator, and grow it from there. However, I seem to run into simulation issues quite quickly, and the fault finding...

    Another Picaxe Stopwatch

    Wrestling with Blockly I am trying to make the code in blockly for 2 reasons. First, it's easier for a noob. Second, ima teach some kids how to do it and I think blockly is very accessible. They also use Scratch so they are familiar with the interface. It may be cumbersome, but I would like to...
