書き込みアプリケーション avrdudeを実行します
sudo avrdude -p m88 -c usbasp -P usb
-p m88 デバイスはatmega88pa
-c usbasp 書き込み器はusbasp
-P usb インターフェイスはUSB経由
usbaspを接続しないで実行すると
sudo avrdude -p m88 -c usbasp -P usb
avrdude: error: could not find USB device "USBasp" with vid=0x16c0 pid=0x5dc
avrdude done. Thank you.
って、怒られます＾＾
usbaspを接続して再実行
sudo avrdude -p m88 -c usbasp -P usb
avrdude: Warning: Found USB device "USBasp" with old VID/PID! Please update firmware of USBasp!
avrdude: warning: cannot set sck period. please check for usbasp firmware update.
avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
avrdude done. Thank you.
フォームウェアのアップデートが必要ですっていわれます
これは、のちに更新します
ターゲットケーブルがおかしいですよ っていられます
ターゲットに接続します。
ーFコマンドが必要みたいです。
ということで、マイコンに接続して、最後コマンドを発行してみます
sudo avrdude -p m88 -c usbasp -P usb
avrdude: Warning: Found USB device "USBasp" with old VID/PID! Please update firmware of USBasp!
avrdude: warning: cannot set sck period. please check for usbasp firmware update.

マイコンの接続はできたみたいです。
コンパイルしてできた hexファイルを書き込んでみましょう
sudo avrdude -v -p m88 -c usbasp -P usb -F -e -U flash:w:led_test.hex
コマンドが増えてます
-F このフラグがないと書き込みできません
-e イレーズします
-U flash:w:led_test.hex led_test.hexをフラッシュメモリ領域に書き込みます
