All better today 😊 I guess it was a glitch...

Hi Trying to program Picaxe chips via the Blockly Chrome app, but I am getting a "Online complie service is not available. Try again later" message. This is having an impact on my lessons! Can anyone shed light on this? Is it really a temporary glitch, or is that the end...

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?

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

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...

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...

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.

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

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.

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...

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...

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...

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...

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...

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...
