Indeed, Julian Picaxe its actually a small beast. You can do quite a lot of things with it without spending time trying to figure out how to code it. This is also a reason that although I bought the OshonSoft compilers years ago I never got around to actually using them.
Managed to get around testing this after I received the modules. For the test I used the "I/O Independent mode 0" with the examples files stored on the modules from the factory and the speaker used was a small 8ohm 0.5w.
I was able to get reliable playback of the sound files down to about 2.8v...
I think I messed the pinouts somehow on the 40x2. I was under the impression that those pins had PWM support.
@PhilHornby you are right, the Wizards only shows 2 pins. Hpwm might be tha way to go enabling or disablign specific channels.
@inglewoodpete I breadboarded the circuit using a 28X2, I...
Hello. I'm trying to figure out why I can't pulse a LED on B.0 using pwmout/pwmduty when I can turn it on and off without any issues. I tried looking at the command descriptions for any limitations but I didn't find anything relative. I am using the smd version of the 40X2 chip (vB.3).
According to the datasheet it is a 940nm wavelength, which is in infrared zone. Plastics that are infrared transmitting should be fine.
If you need to sense touch, using it as a proximity sensor, you could also consider the TCRT5000 sensor (ir transmitter/receiver pair).
