ATmega162P Arduino Pinout
I will present how to use a microcontroller Atmega162 with Arduino IDE.
I wrote this post as a complement to post AVR / STC51 Dev Board (FKECL PCB). But the information here may be used without the development board.
So if we install an Atmega162 microcontroller on the development board above, we can use Arduino IDE.
1. In the <arduino>\hardware\arduino\avr\boards.txt file, add these lines:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
############################################################## atmega162.name= ATmega162 atmega162.upload.protocol=arduino atmega162.upload.maximum_size=14336 atmega162.upload.speed=57600 atmega162.bootloader.low_fuses=0xFF atmega162.bootloader.high_fuses=0xD8 atmega162.bootloader.extended_fuses=0xFB atmega162.bootloader.path=optiboot atmega162.bootloader.file=optiboot_atmega162.hex atmega162.bootloader.unlock_bits=0x3F atmega162.bootloader.lock_bits=0x0F atmega162.build.mcu=atmega162 atmega162.build.f_cpu=16000000L atmega162.build.core=arduino atmega162.build.variant=atmega162 ############################################################## |
2. Make a folder
[<arduino>\hardware\arduino\avr\variants\atmega162\]
in this folder save file [pins_arduino.h]
3. We will overwrite the file iom162.h in folder
[<arduino>\hardware\tools\avr\avr\include\avr\] with the file attached here: iom162.h
4.File [optiboot_atmega162.hex / optiboot_atmega162.zip] will be saved to:
[<arduino>\hardware\arduino\avr\bootloaders\optiboot\]

Arduino IDE -Selecting Programmer
Here’s a sample code to use a 16×2 display.
