What is the SmartGLCD 240x128?

The SmartGLCD 240x128 is a compact smart display, with many on-board peripherals. It’s designed to become a control interface of your device. Main part of the board is a large 240x128 pixel graphical LCD with a 4-wire resistive touch screen. It features RGB backlight, which can greatly improve user experience, but can also be used as a signaling feature. The heart of the board is PIC18F87K22, an 8-bit microcontroller delivering 12MIPS of processing power. Other modules like USB UART, piezo buzzer, microSD slot and connection pads can be found on board as well. The board is preprogrammed with

UART bootloader. We have also provided a nice example which will give you a great out-of-thebox experience.

2. Power supply

The SmartGLCD board can be powered in two different ways: via USB connector (CN1) using MINI-B USB cable provided with the board

(Figure 2-1), or via side headers (CN2 or CN4) using external 5V power supply (Figure 2-2 and Figure 2-3).

Figure 2-1: connecting USB power supply through CN1 connector

Figure 2-2: connecting external 5V power supply through CN2 connector

Figure 2-3: connecting external 5V power supply through CN4 connector

When the board is powered up the GLCD display will be automatically turned on. The USB connection can provide up to 500mA of current which is more than enough for the operation of all on-board modules and the microcontroller as well.

Page 11

5. Programming with bootloader

Microcontroller is preprogrammed with USB UART Bootloader, which can be used to upload new device firmware. To transfer firmware .HEX file from a PC to MCU you need to use mikro-

Bootloader USB UART application, which can be downloaded from:

mikroBootloader software

note

Before starting mikroBootloader software, connect SmartGLCD to a PC using a USB cable provided with the package.

http://www.mikroe.com/smartglcd/

Upon download, unzip it to desired location and start the mikroBootloader application:

6. Programming with mikroProg

™

programmer

The microcontroller can be programmed with the external

mikroProg

™

programmer which can be connected to the board via CN3 connector. Before establishing this connection it is necessary to solder 1x5 male header to CN3 connection pads. This can be done in both ways: on the bottom, or the top side, as shown in Figures 6-1 and 6-2.

Figure 6-1:

The mikroProg can be attached on the back side of the board. Just solder 1x5 header to back side pads (CN3) before connecting it.

Figure 6-2:

The mikroProg can be also attached on the front side of the board. In this case, solder

1x5 header to front side pads (CN3).

note

If bootloader program is accidently erased you can upload it again through mikroProg programmer.

Program Bootloader18F87K22.hex

10. RGB backlight

Graphical LCDs are only capable of showing monochromatic pixel but not color content. The color of the pixel is determined by the color of the backlight which illuminates the display. SmartGLCD has

the

RGB color backlight

a very useful feature which can give your graphical user interfaces an astonishing look.

Display’s backlight module consists of three LEDs: red, green and blue, which can shine simoutaneously.

LED can be driven by PWM signals coming from three separate microcontroller pins. Duty ratio of the PWM signal determines the intensity of color (or brightness) of each LED. Combined together they can create more than 16 milion different backlight colors.

Page 26

Figure 10-1:

The same graphics with different backlight colors

11. Contrast potentiometer

On the backside of the board there is a small potentiometer which can be used to change contrast of the GLCD. The brighter the backlight, the less contrast you will need to properly display the graphical content.

Figure 13-1:

Buzzer module

The board is also equipped with piezo buzzer. It is an electric component which can be used to create sound when provided with electrical signal. This is usually a PWM signal coming from a microcontroller pin. Before entering the buzzer itself, the signal is amplified by the on-board buzzer driver circuit. Frequency of the signal determines the pitch of the sound and duty cycle of the signal can be used to increase or decrease the volume.
