Minimum System ATMega 8535,16,32
Minimum system ATmega 8535/16/32 schematic circuit that is integrated with RS232 serial communication. Minimum System is a microcontroller circuit that used to work. This circuit usually consists of:
1. Crystal = to generate pulse
2. a series reset = to do the “Restart” work microcontroller
Components that can be used as input and output such as:
1. display = LCD, dot matrix, seven segment, etc.
2. input = keypad, push button, etc.
Schematics above are the minimum system that has been integrated with RS232 serial communication. with the RS232, then the minimum system is ready to be used to communicate between the microcontroller to the computer, or microcontroller to microcontroller.
