This tutorial shows how to connect and use the LCD LM6059BCW. This LCD has a display resolution of 128x64 pixels with high contrast and a white backlight. The outline dimensions are 50.9 x 40.9 x 8.7 mm and the viewing area is 37 x 28mm. To see more specifications, you can find the datasheet here.

Instructions

This example was made based on the serial mode configuration of the LCD. Before making the connections between the Wiring I/O board and the LCD you have to check the jumper configuration, for the serial mode, JP1 (jumper 1) must be in open circuit and JP2 (jumper 2) must be in closed circuit. Now, you have to look for two silver points in the back side of the LCD module named JP1 and JP2 and check if the configuration is in serial mode. If it isn't, use a Soldering Iron to open circuit the JP1 and to close the circuit JP2.

Now you are ready to load the program into the Wiring board, use the code below to test the LCD.

*Suggestion: I recommend to use the Wiring board S because of the LCD voltage supply (3.3 V).

As soon as you load the program into the Wiring board, the Wiring logo appears, if you want to make appear another picture, you should follow this steps:

1. Create a file in an image editor with a 128x64 pixels size.

2. Copy the picture you want to use and paste it on that file.

3. Save the file with 'monochromatic bitmap' format.

4. Look on internet for a program that converts from bitmap to LCD (i suggest 'LCD Assistant') and install it.

5. Load the picture you created on step 3 in that program.

6. Save the output with a .txt extension.

7. Open the .txt file and copy from the first number (after the { ) until the last number (before the }; ) and paste it where the code below indicates you.
