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)

After software is downloaded unzip it to desired location and

start mikroBootloader software.

Tips and Tricks: Speed-up UART data transfer

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:

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).

4. Programing with

external programmer

Figure 4-1: Connecting external programmer

w w w . e k t 2 . c o m

mikroProg programmer can be also attached on the front side of

the SmartGLCD. Just solder 1x5 header to pads CN3. This is ideal

placment if you prefer using mikroProg

instead of bootloader.

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.

There is a

built-in microSD

card slot for microSD

cards provided on the

development system. It

enables the system to additionally

expand available memory space. The

Serial Peripheral Interface (SPI) is used for

communication between the microcontroller and

microSD card.
