You could also try to run the ADC in a timer interrupt to sample at a regular rate. It seems as though there is a large amount to learn to use a rather simple processor like the AVR Referring again to the AVR32 datasheet in section 4.

Honestly, I am most interested in data from real users. Well assessed Mike, my feeling has always been that this family AVR32 is targeted toward high volume consumer products.

You can then use the USB communication part of the function to send back your computed sound volume, to check whether your computations make sense. A significant portion of the current drain for a CMOS processor comes from charging and discharging capacitive nodes, whether memory bits datssheet port pins or registers or whatever.

They are less talkative about the high end or even “typical” use. That is definitely a pebble in my shoes.

To multiply by a fraction, multiply by the numerator and then divide by the denominator. On large systems with caches and a operating system that can put processes to sleep, power consumption can go up as the processor does more work. We’ve already built the microphone preamp circuit on the protoboard, using a JEFT microphone datasheetresistors, capacitors, and an LMN quad opamp.


It datashheet after all dynamic consumption which dominates – flipping bits as it were. To test the servo code, modify firmware so that the LED PWM value sent from the host now sets the servo position as well.

On the host side, the python method usbio sends the RGB bytes and takes the byte buffer values sent from the device to reconstruct the 16 bit ADC sample as shown below: These choices determine the clocks available to individual PWM channels:.

Atmel AVR32 vs Prop

So what I meant by “heavily” is “continuously running doing real work e. Are you sure it wasn’t going to sleep when it had nothing to do? Build the microphone preamplifier on the solderless breadboard to amplifier the microphone signal.

Do some measurements myself. You also need to initialize the servo PWM channel to use one of these available clock sources, to end up with a period of about Hz. Note these instructions are somewhat outdated by switch to Arduino Nano in In your position I’d Lean heavily on Atmel.

And don’t forget to add the include statement at the start of your main. This difference in power depending on what’s running squares with my experience with other microcontrollers.


Now let’s write a main loop that samples the microphone input, computes the average mean square sound level, low pass filters it, and sets the servo according to this sound volume.

To activate the DSP functions, you need to add this module to your project framework, using the menu item Framework. I don’t know why their division routines is lower powered, but something that “just adds” is potentially able to change as many bits as most things.

Counter is a read-only datasheey that lets you examine the current counter value. Demonstrate your working system to Tobi and send your project by zip or.

If you are doing embedded design, learn every micro, if you are a hobbist stick with prop. Vendors go out of their way to show how low power they can be. Let’s use the protoboard for both of these. Refine the rudimentary method suggested below.

We could use software delays to slow things down enough. The tools are excellent and not very expensive or freeso they are within the reach of the average hobbyist. The power consumption is not really a function of which instructions are being executed. Period is a 20 bit value that determines the pulse period.
