Basic Tips
What's the rush? Half the battle with this kind of work is gaining experience - can't fast track that! You're best bet nowadays is to get an Arduino (or clone), or perhaps some...

Basic Tips
As already suggested, it would be worth you experimenting without #define's first since you appear to not quite understand how they work (or at least you're certainly missing a...

Stepper motor control using ATMEGA8
In truth I did not bother to check the device when I saw the OP, but yes that device does contain 2 H bridges. Have you not considered using a newer device? Perhaps one that is...

Stepper motor control using ATMEGA8
One thing I feel worth pointing out, as it would appear from your OP that you only have one H bridge, you'll  need two H bridges to drive a 4 wire (bipolar) stepper...

Auto-off Switch - High Side Switching vs. Low Side Switching.
That's a nice idea, I was originally going to have a touch button to turn the system off right away since the project already has a touchscreen anyway, but that might be another...

ATMEGA328PB Boot Loader
Not sure if Atmel make one, but Optiboot appears to be compatible with the 328PB, and what with Optiboot being the bootloader used by the Arduino platform, and that it's currently...

Auto-off Switch - High Side Switching vs. Low Side Switching.
Ah I see now, so Russel was suggesting:     And you're suggesting:   with the idea being that R2 gives the output from my micro a bit of protection I presume? In...

BLDC CONTROLLER PWM HELP !
No, you need to feed the drivers that are switching the high-sided MOSFETs with a voltage that is whatever your battery voltage is + the gate threshold voltage of your MOSFET is....

BLDC CONTROLLER PWM HELP !
To add to tpappano's warning of why the MAX4427 will not work for high-sided switching... Drivers that use N-channel MOSFETs for both low sided and high-sided...
