king33jp 0:7db6d9893ccb 1 /* mbed library for aitendo SX032QVGA08 TFT module with resistive touch panel.
king33jp 0:7db6d9893ccb 2 *
king33jp 0:7db6d9893ccb 3 * Original library is "SpeedStudioTFT" by 2014 Copyright (c) Seeed Technology Inc.
king33jp 0:7db6d9893ccb 4 * I made by it to the reference.
king33jp 0:7db6d9893ccb 5 *
king33jp 0:7db6d9893ccb 6 * (1) Because there was some mistake in the source, I was corrected.
king33jp 0:7db6d9893ccb 7 * (2) Also, I changed to the source you have to assume FRDM
king33jp 0:7db6d9893ccb 8 * (3) I changed BackLight is PWM controlled.
