I wish to interface ESP-01 to ATMega328P / ATMega8 micros without any type of Arduino IDE or Arduino hardware. Pure raw, AVR's. I want to use AT commands with C to do this. Can anyone assist?

If the AVR CPU is powered by 5 volts DC, then you should use a level converter between the ESP and AVR RX and TX lines. Without the level conversion there may be erratic operation due to the high level mismatch.
