Can I use the debug wire to output debugging data
Hi, I have a PCB that uses ATTINY44 and I want to read some real time (in system) ADC measurements from the ISP header. I have two ideas so far: 1) Build another AVR circuit (...

ATTINY44V BOD disable
I'm using ATTINY44V and I have a problem with the power down current consumption. If BOD is enabled by fuse setting, the current is 22uA. But if BOD is disabled, the current is 0....

Supplier for Serial Cables?
I live in the UK and I need to buy 50 to 100 serial port cables (2 meters in length, 9 pin male to 9 pin female with screw locks). A similar cable is used to connect the STK500 (...

How do you interpret this quote from the data sheet ?
In the ATTINY12 data sheet on page 58, the current consumption in power-down mode should be less than 2uA at 3 volts. However, in note 5 at the bottom of the page it reads: Quote...

Direct Piezo drive.
Is it safe to drive a Piezo tranducer using two port pins like this: First half cycle: Pin A = +5v, Pin B = 0v Second half cycle: Pin A = 0v, Pin B = +5v As Piezo transducers...
