La Suno / Mbed 2 deprecated afero_poc15_180403R

Temporary Connector Reversed Version

Dependencies:   UniGraphic mbed vt100

afero_poc15_180403R , J1 のピン配置を反転させたヴァージョンです。

Color2系を使用するためには以下のピンをジャンパで接続してください。
J1-D7 <-> J1-D0
J1-D6 <-> J1-D1

(調査中) また、こちらでテストした範囲では、
FRDM-KL25Z の V3.3 を、Modulo2 の VCC_3V3 ピンに接続してやる必要がありました。

尚、J1-D1, D0 を使用するために UART を無効にしているため
ログは表示されません。

TFTモジュールについて　
aitendoのTFTモジュールはデフォルトでは8bit bus モードになっています。

半田のジャンパを変えて、SPIの設定にしてください。

サーミスタについて
POC1.5 では サーミスタは 25℃の時に抵抗値が 50.0kΩになる502AT-11 が
4.95kΩのプルアップ(実際は10kΩx2の並列)で使用されていました。

今回の試作では抵抗値が 10.0kΩの 103AT-11 が
5.1kΩのプルアップで使用されていますので、係数を合わせるために
SMTC502AT-11 のコンストラクタを　
R0 = 10.0
R1 = 5.1
B = 3435
T0 = 298.15
で呼ぶように変更しました。

to adjust with 103AT-11 with 5.1k pull-up, the constructor of 502AT-11 is called with R0=10.0, R1=5.1, B=3435, T0=298.15
