なぜか、STM32G071が当たった、よって、Lちか(準備中)(Arduino)

目的
GPIOのテスト

いろいろ
ST様からキャンペーンかなにかでNUCLEOを貰った
STM32G031J6M6の開発用に応募した。
STM32G031がなぜか世界中からない(2022/09/17)
基本STM32G031のプログラムは、そのまま動くはず
いまは、そんなところ
みんな、STM32G031J6M6のすごさにきずくの遅すぎ
STM32G031J6M6のArduinoの半二重シリアルに約2日
かけたのは、無駄では、なかった。

GPIO_Blink_PA5_071_1

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(PA5, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(PA5, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(PA5, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
