Detailed Description

An I2C text LCD library for Displaytronic ACM1602NI-FLW-FBW-M01.

The device does not work with default I2C library due to its slow I2C responce. This library adds some extra waits so that the device can answer to the I2C commands. The interface is basically the same as TextLCD by Simon Ford.

This LCD device is manufactured by Xiamen Zettler Electronics Co. Ltd. and distributed by Akizuki Denshi Tsusho Co. Ltd. http://akizukidenshi.com/catalog/g/gP-05693/ http://akizukidenshi.com/download/ds/xiamen/ACM1602NI-FLW-FBW-M01_DISPLAYTRONIC_%20SPEC%20VER1.2.pdf

Example:

 #include "mbed.h"
 #include "ACM1602NI.h"

 // I2C pins: p9 = sda, p10 = scl
 ACM1602NI lcd(p9, p10);

 // You can specify an I2C object instead.
 // I2C i2c(p9, p10);
 // ACM1602NI lcd(i2c);

 int main() {
     lcd.printf("Hello, World!\n");
     lcd.printf("ACM1602NI\n");
 }
