This is Multiple I2C LCD code. It is written using CCS C Compiler version 5.044. This si tested in Proteus and also Easypic v7 development board with 2 x 20x4 LCDs. LCDs should be hd44780 or compatible. I have used I2C LCDs and I2C LCD modules from Banggood. I will soon post mikroC PRO pic and AVR versions of the code here. With this (...)
I have got my 4x20 LCD working so I can write data to it but I cannot succesfully read the busy flag. This is a 3.3v pic so I am using open drain outputs and 5v tollerant inputs. After scoping the Enable and D7 lines I can see the D7 level is low when it should be reading but my routine (lcd_status) always returns 1. I have been trying all manne

I assume you're using an hd44780 based LCD, as I could understand from other posts of yours. Before reading you must enable the pic to read data from the LCD data pins, so change the TRIS registers values to 1 for the LCD pins (except for En, RS, and RW). Then set RW to 1 (READ) - the LCD will return some data on the LCD data pins. In case of 4-
What a union does is let the compiler know that you want to be able to access the same location in memory in more than one way. So, for a simple example, here's how I do this in my hd44780 LCD code: union { struct { unsigned bit0: 1; unsig

The hd44780 chipset offers either 8-bit or 4-bit data I/O, not 16-bit. The interface and coding method is similar to utilizing the device with an 8-bit pic. There are numerous hd44780 compatible LCD libraries available. Are you coding in C or Assembly Language? If C, what compiler are you using? BigDog
