Audio pitch down code debugging
I am sampling an audio signal of 1 KHz and would like to generate an output which is half of that. ADC & DACs are working properly, however it seems the output freq. is still...

ATtiny44A clock out is 4MHz?
I'm enabling the CKOUT fuse and can see a 4MHz square wave generated on the clock output pin. I thought this should be 8MHz? I believe that is the freq. of the internal...

White LED driver debugging
I'm using the following circuit to drive the backlight LEDs of an TFT LCD module:     Please note that the input voltage was changed to 3.3V from 5V (should not matter...

Qtouch charge share delay value?
I'm going through the app note for the touch solutions and on page 6 it says the following: "The value of Rs should typically be within the range of 1kΩ to 10kΩ. If Rs...

Where is Attiny24a in the Qtouch (for non PTC supporting devices) list?
Microchip provides a spreadsheet which lists the Attiny24a as supporting 1 - 4 channels using the Qtouch lib. for non PTC devices. When I start the Qtouch project builder I can...

Touch sensing AVR placement on PCB?
I would like to integrate two touch sensors (implemented using Qtouch lib.) to a project. The PCB that will host these buttons is a small stripe that will be installed a few cm...

Quick & dirty audio sample mixing ?
I'm sampling an audio signal using the ADC and store the data in a buffer to create a delay effect. I would like to feedback the old data pulled from RAM together with the new...

Attiny816 TCD event configuration using START?
  I'm trying to configure a new Attiny816 project using START (should save time, right?). CLK_TCD0 is already 20e6 Mhz / 8 so 2.5e6 MHz. An event should be generated at 10...

How to break on event generation?
I have a counter that generated events on an attiny816 and I would like to see that the event actually happens in simulation. what would be the simplest way to do this?

Is AVR Studio going to be phased out in favor of MPLAB?
I've just noticed that MPLAB supports AVRs (in beta). What's the next move? Killing Studio or running both IDEs in parallel. IMHO Studio is superior.

TCD on Attiny816 configuration to fire event on compare match
I've been reading the datasheet for a while now and I can't figure out the configuration for this timer (TCD) for "clear to timer compare match" mode , which is the only one I can...

Using the Event System as a basis to (almost) CPU free lo-fi audio delay device
The ATtiny816 uses the Event System + I have an external serial RAM hooked-up via SPI. I would like to implement the following "DSP" effects on a sampled signal Delay Echo Pitch...
