Hello, The salesman offered me a discount on the AVR 1909 which he has "in store" literally lol... it's the display model. He offered me this deal... the model has been on in the store for a while I presume he claimed he never really used it or put it on... because he mostly used another receiver. Somebody else says that receivers usually fail in the first year... because component fa...

Ok, So far I listened to the Denon AVR 1909 with GigaWorks S700/S750 speakers... (Ext In. Analog, Out analog) It's night at the moment so only softly. Only 5 speakers have been connected or are in use. The 6th is connected by not using it for now. Still need cable for the 7th. (Also no subwoofer present) When the volume is medium to loud the AVR 1909 probably gives good sound...

Hi all, I'd like to make a very simple frequency counter (should be single chip ideally), let's say to max 25 MHz more or less, 6 digits resolution. A PIC microcontroller, using an internal counter with asynchronous external clock is one possible solution. However, I would greatly prefer to use an AVR microcontroller here as I already have lots of code and experience with them. On the se...

We need a small chip with absolutely lowest power, so for the attiny4: Top of the spec stated 200uA at 1MHz, but nothing about 125KHz. Bottom of the spec has some chart of around 30uA at 125KHz. Can this be trusted? If so, why don't they say so at the top? I would think that's an important marketing data. Can it run at 32KHz like some other AVR chips? Anyone with real experiences?...

Hi! I am designing a touch sensor on an AVR micocontroller. I have been working on the Qtouch library for days now but with no luck, there is nothing to be seen on the pins with the scope after flashing a sample program into the mcu. It has been a big PITA to even get the program to compile because the samples are made for AVR studio and Qtouch studio which are windows-only and I use ...

Knowing that the cheapest AVR device costs about $3-$5 I started to investigate how they could build a complete board with MPU for $5 including shipping. It turns out the Chinese have CLONED the Atmel AVR process

HV AVR comes single phase or three phase. If the power supply is single phase then the choice is obvious but if it is three phase then you have to tell to your stabilizer that you are connecting it to single phase or three phase power supply. The advantage of this option is that a three phase stabilizer serves the purpose of two stabilizers simultaneously. To know more about us please visi...

"Conventional wisdom" says that one should always stick to languages like C and ASM when writing code for "resource constrained" processors like the AVR and el cheapo ARMs. My somewhat-educated opinion is that it's not true. At least, not anymore. Instead of just bloating the code, the constructs available in the recent variants of C++ compilers (C++11 and later) allow you to unleash ...

I notice, each morning, that several of the UPS's engage at nearly identical times. No visible dropouts (i.e., lights don't flicker). UPS's claim either "distorted input" (which typically leads to a ~1 second event) or "AVR" (which persists for 10-15 seconds at a time). [The latter doesn't require the unit to switch to battery power] The interesting thing is that it is "like clockwork". ...
