10 3. Programming with bootloader For programming, microcontroller use bootloader program which is preinstaled in to MCU memory. To transfer.hex file from a PC to MCU you need bootloader software (mikrobootloader) which can be downloaded from: smartglcd-240x128-board/ After software is downloaded unzip it to desired location and start mikrobootloader software. Figure 3-1: mikrobootloader software note Connect SmartGLCD with a PC before starting mikrobootloader software Page 10

11 Identifying device COM port step 1 Choosing COM port Figure 3-2: Identifying COM port Figure 3-3: Selecting COM port 01 Click on Change Settings button note In Device Manager you can see which COM port is assigned to mikromedia (in this case COM5) Select USB COM port (in this case COM5) Set Baud rate to Click OK button Page 11

12 step 2 Connecting with a PC step 3 Browse for.hex file Figure 3-4: Connecting mikromedia with mikrobootloader Figure 3-5: Browsing for.hex file From drop down list Select MCU chose PIC18 Reset SmartGLCD and within 5s click on Connect button 01 Click on Browse for HEX and from pop-up window (figure 3-6) select.hex file which will be uploaded to MCU memory Page 12

13 step 4 Select.hex file step 5 Uploading.hex file Figure 3-6: Selecting.hex file 01 Select desired.hex file 02 Folder list 03 Click on Open button Figure 3-7: Begin uploading 01 Click on Begin uploading button to start.hex file transfer from a PC to microcontroler Page 13

14 step 6 Progress bar step 7 Reset MCU Figure 3-8: Bootloading progress bar Figure 3-9: Uploading is finished 01 Via progress bar you can monitor.hex file uploading process 01 Click on OK button after uploading is finished. Reset MCU and you can see product of your work Page 14

15 Tips and Tricks: Speed-up UART data transfer note If.hex file transfer from your PC to MCU is to slow you can try to speed-up data transfer by seting latency time of COM port to 1. To change latency time go to Device manager: Right click on USB Serial Port (COM5) and click on Properties In USB Serial Port (COM5) Properties select Port Settings tab Click on Advanced... button Set latency Timer to 1 (or chose another value) and click on OK button Page 15

16 4. Programing with external programmer Figure 4-1: Connecting external programmer The microcontroller can be programmed with external programmer mikroprog. The external programmer is connected to the development system via marked pads CN3, Figure 4-1. In order to connect the external programmer to the development system, it is necessary to provide a 1x5 header that should be soldered to pads CN3. If bootloader program is accidently erased you can upload it again via mikroprog programmer. Program Bootloader18F8722.hex can be found under Firmware folder (page 10). Page 16

17 mikroprog programmer can be also attached on the front side of MCU- the SmartGLCD. Just solder 1x5 header to pads CN3. This is ideal placment if you prefer using mikroprog Always use side with a knob of IDC connector for connecting MCU-PGC MCU-PGD MCU-MCLR PGC-RB6 PGD-RB7 MCLR instead of bootloader. with 1x5 header. IDC10 connector Figure 4-2: Connecting external programmer (GLCD side) Page 17

18 5. Touch Screen The development system features a Graphical LCD 240x128 display covered with a resistive touch panel. Together they form a functional unit called a touch screen. It enables data to be entered and displayed at the same time. The way of entering and displaying data depends on the program loaded into the microcontroller. Resistive touch panel is suitable for usage with a plastic pen which have rounded tip. Finger press is always available but bare in mind that you use touch panel and there s no need for too much pressing force. Page 18 Figure 5-1: Touch Screen
