WUni232cでArduino Unoに書込する。

Last updated at 2021-12-19Posted at 2021-12-19

昨日に引き続き　やましょうです。

Arduino Unoのブートローダ側のソース

まずArduino側のブートローダーのソースは下記にありますね。
https://github.com/arduino/ArduinoCore-avr/blob/master/bootloaders/atmega/ATmegaBOOT_168.c

ソースと通信ログから見るとpcから送付する20は終端コードな模様

delphiでArudino Flashを書き換えてみる。

Arudinoのソースはサンプルのblinkの時間を1000msと500msに変更したhexを
delphiに内包しています。
とりあえずボタンでArudino Unoを書き換えるコードを下記に示します。
若干書込みは遅いのですが、こんなに簡単な一つのボタンの処理で書き込むことができます。
とりあえず書込みできるか？どうかのチェック用のコードなので、
実際に製品として使用するには、ベリファイや、戻り値による確認処理の追加が必要です。
ってことでuni232c使うと簡単に書くことができます・
