Good Display co., had invented 2.1”, 3.5”, 4.3” and 6” inches
simplified E-paper demo kits in 2013. Normally this
component is very easy for the ‘C code’ programmers to
handle it. In additional, the demo kit’s very good
compatibility with C code’s underlying system functions.
We strongly recommended you to use the Keil as IDE for
compile, it’s simple to modify and observable. The whole
procedures rely on to integrate of Debugger and Keil3
software.
From the hardware aspect, there’s a bit different between
2.1” and other types of kits. Even the Arm (MCU) we settled
on this kit is the same, but for this specific resolution of use
it able to forward images shuffle and contains more lanes of
command. Another point, the 2.4” pin connector is not joint
the share use with other FPC.

Structure：
For the representing use, you just have to install an e-paper on
kit and connected to a PC thru an USB power cable then all will
be done.
For every Demo kit, there got be a LED power light exists on
board.

E-ink paper Demo Kit Manual |5
While at working status: Green light is appearing, Otherwise, light
distinguished. You could optional choose an USB or AC power
supplier to consumes power by switch the jumper wire.
Mentioned that, the USB connector on kit board couldn t use for
data stream. Therefor it can t be download by this way. To
download your programs from PC to the kit you may use a
standard JTAG port debugger to implement.
1. Link the debugger by JTAG cable to the kit. (Image shows the
right position)

E-ink paper Demo Kit Manual |6
2. Link the other side of debugger to PC by USB.
We knew the exactly how to link it up. Now you require a PC that
runs a Keils3 (registered) or higher version. In addition you need
to make sure all your stuffs are linked in.（5Vpower Demo Kit
JTAG Debugger USB）

Settings：
Double clicks your Keil icon on desktop or windows start to run it:
1. Open the project > Right click the project root DIR > Select
Options for Target > Click Debug Tab, Find the J-link JTAG
debugger and press the setting.
(Procedures listed on pictures)

After UPLOAD your Debugger to Keil press OK to save it.
2. Click the Utilities tab select J-Link JTAG and do the similar
steps copy previous one, also settings.

WARNING：When you done your Debug and Utilities Settings,
remember to check the FlashDownload tab in those settings. If
it does come up with STM32F10x 128K, please manually
added it.
3. Find our MCU module in Device Tab and press [OK] to save,
After that click User Tab and deselect Run user pro keep the
tick box and text field empty, finally go to Output Tab and tick
the create a HEX file after compile .

Compile：
To compile your code just click on the build button on left top of
window. You must compile before debug. The Build Output
window shows all detail you may interest to know. You also can
observe if there s any error or interrupt existed and mark the lane
it is. Careful check that the HEX file is successfully created for
your next step.

Download：
Moans that again please check your Debugger and Demo kit
correctly connected and powered up. The debugger and your
kit s LED bulbs should be lightning or flashing. Click the
Start/Stop Debugger session button to download it to your MCU
and enter to debug mod.
The button is on your top right.

Modify：
You may set the temporary pause by double clicks a particular
lane of source and observe it. Use step button can move to your
the next pause. When you use this to perform your work to check
the reactions please always download it to ARM after modify.
That’s because of it’s more reliable to keep the ARM had your
latest update of the program.
Generate an image static number table [] ：
•Technically it’s perfectly fine for any software you could download
from the Internet that make the same purpose. However if you
don’t have any idea of what it is I would recommend you to use
the BitmapCovert to implement. You need to insert a [*.bmp]
format image to the window and drill the unattainable color off.
So make sure the resolution is right, the gray scale is attainable
by check the datasheet. Check the frame is portrait or landscape

E-ink paper Demo Kit Manual |15
then flip turn the image in window to correct. When everything is
right, just click the file in toolbar, and then click save as [.c]
format txt file. Remember to fill the [without template] tick box,
that makes sure you won t see too much useless code in that file.
Replace the const number [] of our program with the new one
we just generated. Now an image is replaced.

E-ink paper Demo Kit Manual |16
During you save it from BitmapCovert to local disk, the
format you need to select in this widow is the numbers of
bit will applied per pixel. So you better to check it with a
proper datasheet.

The red square marked the hex numbers in text that you
looking for to copy. And these numbers below need to be
replaces with.
