HD44780 by Hitachi was the first popular LCD controller and then came many compatible / clones of this IC. Your Tianma TM162A is based on the KS0032 which is most likely a clone. Your pinout looks the same as the example but you are defining the s/w to treat the display as a 20x4. Try with the following:
#include "mbed.h" #include "TextLCD.h" TextLCD lcd(p15, p16, p17, p18, p19, p20, TextLCD::LCD16x2); rs, e, d4-d7
Setting the type field in the TextLCD constructor allows configuration for the different display panel sizes: TextLCD::LCD16x2 16x2 LCD panel (default) TextLCD::LCD16x2B 16x2 LCD panel alternate addressing TextLCD::LCD20x2 20x2 LCD panel TextLCD::LCD20x4 20x4 LCD panel Note: There is now also support for TextLCD::LCD8x1 8x1 LCD panel TextLCD::LCD8x2 8x2 LCD panel TextLCD::LCD16x1 16x1 LCD panel TextLCD::LCD16x4 16x4 LCD panel TextLCD::LCD24x2 24x2 LCD panel TextLCD::LCD24x4 24x4 LCD panel (for KS0078 controller) TextLCD::LCD40x2 40x2 LCD panel TextLCD::LCD40x4 40x4 LCD panel (two controllers)
