AVR works after pressing Reset Button
You have 24V 20A power why?   Perhaps there are some other "big" loads that make the ground jump. (I expect that 24V and 5V share ground).   Does the chips control some...

Solved: MEGA328PU-TH and cold - Junk in serial communication
ok first I assume that OP use full swing osc, (not low power that only should be used up to 16MHz).   Perhaps Microchip again try to produce mega328P on the same line as...

Getting started ATtiny 1 & 0 series / Application Notes
And the big question for me is why don't it get changed, when it's clear for the one that did the app-note know that the data sheet is wrong (or perhaps he knew that using TX...

Watchdog Timer on the 328p makes a GREAT temperature sensor!
I think that it's because "Arduino-land"  don't like hacks!    The problem is that things like this is hard to make modular, so many things can work together...

Watchdog Timer on the 328p makes a GREAT temperature sensor!
It's old news, somewhere here there is a thread for a tiny85, that do the same.   And in the real world I don't beleive 0.005 C !!! (or give me a way to make 5.0000V...

Simple 3D graphics on an AtMega microcontroller
first a 80286 needed a 80287 to have FP. (as I remember the 80486 DX was the first with buildin FP (there was a SX without)).   Which display do you use ? (some displays...

Solved: MEGA328PU-TH and cold - Junk in serial communication
None of the two "OP's" have told about which Voltage they run at, and like the graph on #11 show that matter when you use the speed out of the bag.   When you want 9600 Baud...

[FAQ]: Call instruction simulation in Atmel Studio 7
This is the same as rcall can flip over on chips with more than 8K flash.   From the datasheets on AVR's with 8K flash it's clear that rcall can reach all the flash, but it's...

USART in MSPI mode as a fast shift register
I would not use sleep it's faster to jump to 30 nop's (or whatever is needed) then there will be no jitter on the ISR , and no extra clk to start from sleep.

USART in MSPI mode as a fast shift register
I have to ask what else do you need to do? And which dot clk speed do you need ? (and AVR speed for that?).   And the line timing, number of visible lines and total...

USART in MSPI mode as a fast shift register
I don't know what speed you need, just remember if you use a crystal for your chip a 328PB can only run 16MHz , not 20MHz.   I don't know how you make the sync pulses, but...

Atmega32 VCC and GND pins shorted
I also use 1N400n diodes, and if it don't blow a fuse somewhere before any damage you have a big problem with your power line !
