AVR generated 12v pulse, just for fun
Perhaps they have an other name, it was a bead about 7 mm i diameter (I lived in US at that time so 1/4 inch I guess)made out of ferrite. It had a hole about 3mm, and...

AVR generated 12v pulse, just for fun
Back 20 years ago I made 12V just for fun with a 8515 with a ferrit bead as a transformer, and I was surprised that I actually could make 12V 5ma with just 2 5V port pins....

Oscillator calibration. Or decallibration
bluethooth If you have  Bluetooth I would expect it have a good clk can't you use that ?   Don't make jumps, rather make a "very" slow PLL(or PID), so if it's...

Oscillator calibration. Or decallibration
We are missing what you really want to do. If it's something like a UART where you need something like better that 3% (or 4% or 2% depends) it's fine to calibrate. But it's a...

Measure time consumption of programme
I don't know what kind of tools there are but I would look i the generated code, and run it with the simulator (it's clk accurate ) and set break points different places.  ...

Pin current consistency / atmega 4809
from #1 you wrote :   I've got a breadboard up and running Are you 100% sure that the power to the AVR are consistent in your setup, and it's not just a voltage drop over...

Success story with LGT8F328p in linux
The first Atmel cpu's like the AT89C2051 was "real" Intel chips, meaning that Atmel payed royalties to Intel. For atmel it was a fast way to get into CPU marked (remember Atmel...

Just debug in disassemble mode, than you can see what the code do.

What was your first micro programming experience?
And you only had to look at them, and they was killed of static :(

What was your first micro programming experience?
There are free C compilers for cp/m. (In that case I would probably use a turbo pascal, as I remember it was given free a while back  )

324PB max gnd and vcc current...
Also remember that the 100mA is GND and VCC pins but when you have a IO load, the power only run thru one of the pins :) So you can sink 100mA and source 100mA, so do some...

The 324PB is like 328PB made on a newer proces (best know as those where the high power osc. don't work).   Those chips are for toy and hobby, avoid using them ...
