Motoo Tanaka / Mbed OS TFT_test_MAX32630FTHR

My first mbed-os 5.x test project with MAX32630FTHR and Adafruit 2.4" TFT with touch.

Dependencies:   BMI160 SPI_STMPE610 USBDevice UniGraphic max32630fthr

My first test program of mbed-os 5.x, using MAX32630FTHR and Adafruit 2.4" TFT with Touch.

On 22-Sep-2017 Monitoring both Acc and Gyr added to the screen 3 Controlling the backlight via STMPE610 GPIO-2 added

The backlight control of ILI9341 is not connected to the MCU, but gpio-2 of STMPE610 is, so I used STMPE610 to control ILI9341 backlight enable.

Who changed what in which revision?
