Japaninoを使ってみる

大人の科学'Japanino’を買ってみた。
使いやすくていいね！

まずは7セグメントLED(4桁)を点灯させてみました。
それだけではつまらないので、AD変換で、電圧計にしてみました。

　byte _7seg_table(byte ttemp){
  byte seg;
  switch (ttemp) {
  case 0:
    seg = B01111110;//  ０　１１１１１１０
    break;
  case 1:
    seg = B00110000;//　１　０１１００００
    break;
  case 2:
    seg = B01101101;//　２　１１０１１０１
    break;
  case 3:
    seg = B01111001;//　３　１１１１００１
    break;
  case 4:
    seg = B00110011;//　４　０１１００１１
    break;
  case 5:
    seg = B01011011;//　５　１０１１０１１
    break;
  case 6:
    seg = B01011111;//　６　００１１１１１
    break;
  case 7:
    seg = B01110000;//　７　１１１００００
    break;
  case 8:
    seg = B01111111;//　８　１１１１１１１
    break;
  case 9:
    seg = B01111011;//　９　１１１００１１
    break;
  case 10:
    seg = B01110111;//　A
    break;
  case 11:
    seg = B00011111;//　b
    break;
  case 12:
    seg = B01001110;//　C
    break;
  case 13:
    seg = B00111101;//　d
    break;
  case 14:
    seg = B01001111;//　E
    break;
  case 15:
    seg = B01000111;//　F
    break;
  default:
    seg = B00000000;//  ０
  }
  return ~seg; // LOWでONなので反転
