two timers using single 555
A couple of points for the 555: The NE555 variants can source 200mA, far more than the AVRs. Also, they work up to 15V, which is handy if you want to drive MOSFETs directly. If...

BASCOM demo limit
Google says 4K. Perhaps the next time you might want to try that?

I don't have the datasheet with me right now, but I suspect the reason you've been advised to ground A0 is due to the fact that addressing is 8-bit byte aligned. However, the...

C to hardware [for Altera NIOS II]
There is System C, but it still feels like writing verilog. AutoESL also has AutoPilot, which is one of a class of high-level synthesis tools. Perhaps ask for a demo?

Finding the right oscilloscope
I've got an Instek GDS-1102A. The A suffixed models have a 2M/channel capture depth when triggered in Single mode, which is nice to decode long I2C or SPI trains. However, the on-...

Measure sinusoidal frequency with ATmega32
If you'd show us what you've done, we'd be able to guide you in the specific areas that you are experiencing trouble in. We're not going to do your project for you.

Driving a 12V fan with an AVR
Remember to take into account the fact that, during the switchoff period, the pwm signal is usually inhibited.

How to design something that can last long (years)?
So will the OP be telling us what exactly he's planning to design that requires a power source for that long?

AVR function for confidence interval count
Sure, you're probably welcome to (under the terms of the GPL) extract the relevant bits of PSPP for your application. Whether you have sufficient on-chip resources to do this is...
