ATmega16 question about prescaling a timer
Screw a sample, crack open the datasheet and look in that timer's section to see how they got those code values.

Keypad issue
Your eq'n is correct and the type of math a compiler could use to access a [5][4] array. :wink:

I2C to PC connectivity options ?
PCs don't have I2C I/F, so you'd HAVE to put something between them. Which is just going to slow things down. Use a correct I/F for the job...USB or UART.

ATmega16 question about prescaling a timer
By "system", do you mean the toolchain ? If so, the only thing you give it is the F_CPU number, 14_point_whatever MHz. Then you just set prescaler in TCCR1B.

ADC problem with ATtiny461
I know you want to use it as a dimmer, and it is blinking, just too fast to follow. I figured persistance of vision wouldn't allow the brightness changes to be seen at such short...

ADC problem with ATtiny461
Your software PWM has a f = 490 Hz ( 2mS ) with Fcpu = 1MHz, 8 MHz would be 8X worse ! We can only see blinking out to about 40 Hz. Try a bigger timer prescale. Do you have an o....
