5. Programming with bootloader Microcontroller is preprogrammed with USB UART Bootloader, which can be used to upload new device firmware. To trans mikroBootloader software note fer firmware .HEX file from a PC to MCU you need to use mikro Bootloader USB UART application, which can be downloaded from: Before starting mikroBootloader software, connect SmartGLCD to a PC using a USB cable provided with the package. http://www.mikroe.
Identifying device COM port step 1 – Choosing COM port 01 02 03 Figure 5-3: Choosing COM port Figure 5-2: Identifying COM port 01 Click the Change Settings button. 02 From the drop down list, select appropriate Port (in this case it is COM18) and Baud rate (115200). 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). 03 Click OK.
step 2 - Establishing Connection step 3 - Browsing for .HEX file 01 01 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.
step 4 – Selecting .hex file step 5 – Uploading .hex file 01 01 02 Figure 5-6: Locating and selecting .hex file Figure 5-7: Begin uploading 01 Select .HEX file from the Open dialog window. 01 In order to upload .HEX file click the Begin uploading button. 02 Click the Open button.
step 6 – Progress bar step 7 - Finishing upload 01 01 Figure 5-8: Progress bar Figure 5-9: Restarting MCU 01 Progress bar enables you to monitor .HEX file uploading. 01 Click OK button after the uploading process has been finished. 02 Press Reset button on SmartGLCD board and wait for 5 seconds. Your program will run automatically.
Tips and Tricks: Speed-up UART data transfer 02 04 03 01 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: 01 Right click on the USB Serial Port (COM18) item and then select Properties. 02 Select Port Settings tab. 03 Click the Advanced... button. 04 Set Latency Timer to 1 and click OK.
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.

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.
11. Contrast potentiometer On the backside of the board there is a small potentiometer which can be used to change Figure 11-1: Constrast potentiometer contrast of the GLCD. The brighter the backlight, the less contrast you will need to properly display the graphical content.
12. USB UART Figure 12-1: Connecting USB cable to SmartGLCD board Fast on-board FTDI® chip allows you to communicate with a PC or other UART devices using USB UART connection. Before connecting the board to a PC, make sure that you have the appropriate FTDI drivers installed on your operating system.

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.
