Easy TFT is target to the users updating their product from monochrome LCD to TFT displays or new
products fast developing, our solution can provides a simple and reliable way to control TFT displays. M7-M
series include small screen with RGB port from 3.5” to 8”, meeting the requirements for various applications
from customers.
1. The bottle neck of MCU speed is solved: compared with the black and white module, the data volume of
color screen is much larger and require rapid data refresh while updating interface, which cannot be satisfied
by traditional MCU, otherwise the responding speed of whole system will be very slow.
2. The data storage space of common MCU is within 64K, which is not enough to store one picture for TFT
displays; our module adopts an MIN-SD card to store picture data and this is quite enough for common
interface design.
3. The technology of TFT displays change quickly and the driver IC updating fast, the product life time can’t be
guaranteed. The software and hardware is required to change often in order to adopt the new displays, which
brings a lot of extra work. Our solution can help customer to solve the problem, when there is screen change,
we can adopt it on our mainboard, the consumer don’t need to changing their software and hardware.
4. The adoption of alphabetic string command for module control is simple and clear; only need MCU output
“Hello World” from the UART
5. The user copy pictures from computer to the SD card, saving a lot of work like general modeling and
compiling etc. and development time is shortened.

1. Firstly, put all pictures needed into the folder of BMP_FILE, convert them into BMP format and change
picture names in proper sequence from 000.BMP. The operation can be completed with software of ACDSEE;
see Appendix I for details in operation.
The picture files with names in proper sequence are shown in figure below:
2. Execute batch processing command Bmptobin.exe and two files will be generated in the folder of
BMP_DATA after execution, among which BMPDATA.BIN is the data file where all picture data are put
successively and TABLE.BIN is the table file equivalent to index file; copy these two files into the folder
virtualized by the module and then they are available for use.
3. If special character display is required by user,like Chinese or Japanese etc.The software attached in this
module can be used for extracting font library; see Appendix IV for details.(Only for Chinese version)
Revise the name of extracted font library file and copy it in to USB flash disk for application; the file name
should be changed as HZK.BIN.
4. Press K1 key (reset key) on module after all files are copied into SD card and then they are available for use.

Note:
* Using the command ,there will be a return value format is a "SXY Xsize Ysize\n"
“\n” : 0x0d & 0x0a
** Animation display can have up to 4 groups, each group of pictures must be
continuous and each picture size must be the same, the total amount of data
is less than 1MB
