== Introduction  ==
'''TFT01_2.4''' is a TFT LCD Screen Module , 40pins interface , not just a LCD break but include the '''Touch''' , '''SD card''' and '''Flash''' design. So it’s a powerful extension module for your project.<br>

The Screen include a controller [https://aptofun.de/images/8/81/EF03100-S6D1121-datasheet.pdf S6D1121] replace of [https://aptofun.de/images/3/33/EF03100-ILI9325.pdf ILI9325], it’s a support '''8/16bit''' data interface , easy to drive by many MCU like STM32 ,AVR and 8051 etc.<br>

*TFT01 is designed with a '''touch controller''' in it . The touch IC is [https://aptofun.de/images/e/ee/EF03102-ADS7843.pdf ADS7843] , and touch interface is included in the 40 pins breakout. We will offer two version of the module, one is with touch screen and touch controller , another is without the touch function, it will just use as a LCD screen for display- so it will be inexpensive than former.<br>

*Another useful extension in the TFT01 is the '''SD Card socket''' . It use the '''SPI''' mode to operate the SD  card, the SPI interface include in the 40pins breakout.<br>

*There is a reserve extension design in the TFT01 , that’s the '''external flash''' . It’s leave the pad and the pins out for the '''SST25VF016B''' Flash. So when you need , you can easily add a external flash for your project .<br>

The TFT01 layout a 40 pins interface for your project , the interface include '''LCD bus''', '''SD card bus''', '''Touch screen bus''' and '''the Flash bus.'''<br>

'''Model: TFT01_2.4'''

== Feature ==
*Extensive bus interface
*Single chip solution for a liquid crystal QVGA TFT LCD display 
*240RGBx320-dot resolution capable with real 262,144 display color 
*Support MVA (Multi-domain Vertical Alignment) wide view display 
*Internal oscillator and hardware reset
*Partial drive function, enabling partially driving an LCD panel at positions specified by user 
*Power saving functions 
**8-color mode 
**standby mode 
**sleep mode 
*Low -power consumption architecture 
*Size:530mm * 750mm

== Application Ideas  ==
*Digital Photo Frame （DPF）
*Video terminals
*Instrumentation
*GPS
*Game consoles
*Video phones and Portable VCD, DVD

== Cautions  ==
<font color="red"> <strong>
*TFT01 default use the 8bit mode , and if you need the 16 bit mode, you can tear the LCD screen down form the board , and move the R2 resistor to R1 to change the data mode. It’s a hard job , and easy to destroy the screen, so if you need a 16bit mode , you had better tell us before shipping , we will set the data mode for you. 

*When you use the 8bit mode , the DB8-DB15 is used ,please remember to pull the DB0-DB7 to GND.

*The I/O of the Panel is 3.3v voltage , so you had better not to directly connect it to the 5v voltage I/O .We suggest using the 30K and 20K resistor to reduce voltage.

== Schematic  ==
[[File:2.4 TFT LCD 3.jpg  | 800px]]

== Specification  ==

== Pin definition and Rating  ==
[[File:2.4 TFT LCD 4.jpg  | 600px]]

The pins named with '''“D_”''' is the touch bus , the pins named with '''“SD_”''' is SD bus, the pins named with '''“F_”'''  is Flash bus.

TFT01 is work at 3.3v DC, if you need to connect the module with the 5v voltage I/O , you need to add the 30k and 20k resistors to reduce voltage.

== Usage  ==

=== Programming  ===

Includes important code snippet. <br>
All of the Demo used ''' TFT01 Shield v1.0 ''', that just support 8 bit mode, because of Arduino Limited IO, You could setting 10 PIN to CS the Touch or SD card function. Download the below code, and run on  TFT01 Shield v1.0 .
If you want use 16 bit mode and touch function, you could used ''' TFT-01 Mega Shield v1.1 ''', which for Mega1280 or Mega2560 and there are enough IO for Touch and SD card function .

 '''Old Controller Demo code'''

==== 16 bit Pant Demo code ====

<syntaxhighlight lang="c">
/*
 This example code is 16bit mode for TFT01 demo.
 
Connect the pins to Arduino first :
DB0-DB16 to pin D0-D13 , pin A0-A1 of Arduino
RESET to A2
CS to A3
WR to A4
RS to A5

All the data pins of Arduino is used ….So , we just can connect the RD to 3.3V.
We don’t used it because we don’t need to read back the data from the screen.
Connect the power pins : LCD-A to 3.3V , VCC to 5V , GND to GND

Note that the LCD is use the 3.3V voltage level , so if you want to connect the 5V Arduino pins to it , 
you need add a resister about 20K to reduce voltage. We use the 3.3V Arduino Pro which work in 8M , 
so we connect the pins directly — this is why we used 16 bit mode, 8 bit mode is too slow to refresh the screen.
