4 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. Page 4

11 4. Programming the microcontroller Figure 4-1: PIC18F87K22 microcontroller The microcontroller can be programmed in two ways: Using USB UART mikrobootloader Using external mikroprog for PIC, dspic, PIC32 programmer Page 11

12 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. Upon download, unzip it to desired location and start the mikrobootloader application: Figure 5-1: mikrobootloader window 01 When you start mikrobootloader software a window should appear, as shown in the image above. Page 12

13 Identifying device COM port step 1 Choosing COM port Figure 5-2: Identifying COM port Figure 5-3: Choosing COM port 01 Open Device Manager window and expand Ports (COM & LPT) section to check which COM port is assigned to SmartGLCD board (in this case it is COM18) Page 13 Click the Change Settings button. From the drop down list, select appropriate Port (in this case it is COM18) and Baud rate (115200). Click OK.

14 step 2 - Establishing Connection step 3 - Browsing for.hex file Figure 5-4: Connecting with mikrobootloader Figure 5-5: Browse for HEX 01 Press the Reset button on SmartGLCD board and click Connect within 5s, otherwise the existing microcontroller program will run. If connected, the button s caption will be changed to Disconnect. 01 Click the Browse for HEX button and from a pop-up window (Figure 5-6) choose a.hex file to be uploaded in MCU memory. Page 14

15 step 4 Selecting.hex file step 5 Uploading.hex file Figure 5-6: Locating and selecting.hex file Figure 5-7: Begin uploading Select.HEX file from the Open dialog window. Click the Open button. 01 In order to upload.hex file click the Begin uploading button. Page 15

16 step 6 Progress bar step 7 - Finishing upload Figure 5-8: Progress bar Figure 5-9: Restarting MCU 01 Progress bar enables you to monitor.hex file 01 uploading. 02 Click OK button after the uploading process has been finished. Press Reset button on SmartGLCD board and wait for 5 seconds. Your program will run automatically. Page 16

17 Tips and Tricks: Speed-up UART data transfer note If.HEX file transfer from your PC to MCU is too slow, it s possible to speed up data transfer by setting latency time of COM port to 1 ms. This is done in Device Manager: Right click on the USB Serial Port (COM18) item and then select Properties. Select Port Settings tab. Click the Advanced... button. Set Latency Timer to 1 and click OK. Page 17

18 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 can be found under Firmware folder (page 12). Page 18

20 7. mikroprog Suite for PIC Software The mikroprog programmer requires special programming software called mikroprog Suite for PIC. It can be used for programming all Microchip microcontroller families, including PIC10, PIC12, PIC16, PIC18, dspic30/33, PIC24 and PIC32. The software has intuitive interface and SingleClick programming technology. Just download the latest version of mikroprog Suite and your programmer is ready to program new devices. mikroprog Suite is updated regularly, at least four times a year, so your programmer will be more and more powerful with each new release.

26 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. Figure 10-1: The same graphics with different backlight colors Page 26

27 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 11-1: Constrast potentiometer Page 27

30 13. Buzzer 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. Page 30
