Masato YAMANISHI / Mbed 2 deprecated TextLCD_SB1602E

added puticon() for SB1602B

Dependencies:   mbed

Fork of TextLCD_SB1602E by Tedd OKANO

Tedd OKANO さんの Strawberry Linux の i2c LCD SB1602E ライブラリに SB1602B のアイコン表示メソッドを追加。STM32 Nucleo L152RE/mbed でテストしてます。 /media/uploads/masato/sb1602b.jpg

こういう時は Pull Request すべきなのかな。
