A simple meter using Adafruit 2.8 TFT with touch v2
Dependencies: SPI_STMPE610 UniGraphic mbed vt100
A dumb simple voltage tester using ADC.
With FRDM-KL25Z, you can measure about 0V to 3.28V.
Nothing to drop your jaw nor holding your breath
but I wanted one, so I wrote one ;-)
とても単純はADCを使用した電圧テスターです。
FRDM-KL25Z を使用した場合、0V ~ 3.28V くらいが測定範囲です。
特に目新しいことも、驚くこともありませんが、
自分が欲しいので書いてみました (^ - ^)

I changed the number display from 0.00 to 0.000
so that I can measure the change of a small loadcell.

ロードセル (重量センサ)の出力値の変化を見たかったので
有効数字を小数点以下2桁から3桁に変更しました。
