If you are saying this is not because of instruction differences, what is your alternate explanation?
These choices determine the clocks available to individual PWM channels:. Some hints for signal processing using fixed point: It has a memory control unit and is designed for lots of memory 16MB and upagain It seems as though there is a large amount to learn to use a rather simple processor like the AVR On large systems with caches, variable clock, and other fancy stuff it can certainly vary a lot, but you asked about a microcontroller.
In this exercise, let’s build a microphone preamp on the protoboard, acquire the audio signals on the AVR32 using the ADC, process the auditory signal to measure the RMS power sound volumeand then use the average sound volume over the past few hundred ms of time to set the position of a servo motor.

Comparing the AVR32 against the Prop is apples and oranges, mind you with clever programming the Prop can do amazing things. If you finally have to give up for lack of time or success, see how to make the mic-servo datasheeet work.
It’s either running or not running. You will end up with about 4V to power the servo which is on the low side but it should still work. To better work in python, you may want to install in Eclipse the plugin to handle python datxsheet. Counter is a read-only register that lets you examine the current counter value.
I’m not that up on AVRs, but other micros I am familiar with don’t exhibit much change in power at all depending on instruction. Except where otherwise noted, content on this wiki is licensed under the following license: I have the AVR network board.
Period is a 20 bit value that determines the pulse period.
A significant dtaasheet of the current drain for a CMOS processor comes from charging and discharging capacitive nodes, whether memory bits or port pins or registers or whatever. No assertions from me: Well assessed Mike, my feeling has always been that this family AVR32 is targeted toward high volume consumer products.
You demo should end up responding to transient dattasheet volume increases by turning the servo. We won’t worry about putting the ADC sampling in a timer interrupt routine for now. That is definitely a pebble in my shoes. Thanks for your answer, you make some good points.
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:.
Atmel AVR32 vs Prop
Post as a guest Name. Russell McMahon k 9 See this example to start. Remember that you only have fixed point hardware.
An existing LED channel looks like this:. It’d be a good fit for a router or firewall or small Linux workstation. Adapt the PWM code to control the servo. Prop is great place to start to learn multiple parallel processing.
This difference in power depending on what’s running squares with my experience with other microcontrollers. You could also try to run the ADC in a timer interrupt to sample at a regular rate.
I am terribly limited by not fully deep-diving into Prop ASM.
Those Who Can’t, Teach. Does anyone know of power-estimation spreadsheet or tool, or have measured power data for the Atmel AVR32 UC3L Series when running heavily in a real application? They are less talkative about the high end or even “typical” use.
