Master can control Reset & INT pin to configure the slave address in power on initial state like following: Power on diagram: Timing for setting slave address to 0x28/0x29: Timing for setting slave address to 0xBA/0xBB:
URL: www.topwaydisplay.com www.topwaysz.com Document Name: LMT050DICFWD NNC Manual Rev0.1.DOC Page: of 7.3 I C Data Transmission (For example device address is 0xBA/0xBB) Communication is always initiated by the host. Valid Start condition is signaled by pulling SDA linefrom “high” to “low” when SCL line is “high”. Data flow or address is transmitted after the Startcondition. All slave devices connected to I2C bus should detect the 8 bit address issued after Start condition and send the correct ACK. After receiving matching address , GT911 acknowledges by configuring SDA line as output port and pulling SDA line low during the ninth SCL cycle. When receiving unmatchedaddress, namely, not 0XBA or 0XBB, GT911 will stay in an idle state. For data bytes on SDA, each of 9 serial bits w ill be sent on nine SCL cycles. Each data byte consists of 8 valid data bits and one ACK or NACK bit sent by the recipient. The data transmission is valid when SCL line is “high”. When communication is completed, the host will issue the STOP condition. Stop condition implies the transition of SDA line from “low” to “high” when SCL line is “high”. CTP I C Data Write (For example device address is 0xBA/0xBB) The diagram above displays the timing sequence of the host writing data onto GT911. First, the host issues a Start condition. Then, the host sends 0XBA (address bits and R/W bit; R/W bit as 0 indicates Write operatio n) to the slave device. After receiving ACK, the host sends the 16 bit register address (where writing starts) and the 8 bit data bytes (to be written onto the register). The location of the register address pointer will automatically add 1 after e very Write Operation. Therefore, when the host needs to perform Write Operations on a group of registers of continuous addresses, it is able to write continuously. The Write Operation is terminated when the host issues the Stop condition. CTP I C Data Rea d (For example device address is 0xBA/0xBB) The diagram above is the timing sequence of the host reading data from GT911. First, the host issues a Start condition and sends 0XBA (address bits and R/W bit; R/W bit as 0 indicates Write operation) to the slave device. After receiving ACK, the host sends the 16 bit register address (where reading starts) to the slave device. Then the host sets register addresses which need to be read. Also after receiving ACK, the host issues the Start condition once again and sends 0XBB (Read Operation). After receiving ACK, the host starts to read data. GT911 also supports continuous Read Operation and, by default, reads data continuously. Whenever receiving a byte of data, the host sends an ACK signal indi cating successful reception. After receiving the last byte of data, the host sends a NACK signal followed by a STOP condition which terminates communication.

URL: www.topwaydisplay.com www.topwaysz.com Document Name: LMT050DICFWD NNC Manual Rev0.1.DOC Page: of Precautions of using LC D Modules Mounting Mounting must use holes arranged in four corners or four sides. The mounting structure so provide even force on to LCD module. Uneven force (ex. Twisted stress) should not applied to the module. And the case on which a module is mounted should have sufficient strength so that external force is not transmitted directly to the module. It is suggested to attach a transparent protective plate to the surface in order to protect the polarizer. It should have sufficient strength in order to the resist external force. The housing should adopt radiation structure to satisfy the temperature specification. Acetic acid type and chlorine type materials for the cover case are not desirable because the former generates corrosive gas of attacking the pola rizer at high temperature and the latter causes circuit break by electro chemical reaction. Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB pencil lead. Never rub with dust clothes with chemical treatment. Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics deteriorate the polarizer.) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like chamois soaks with petroleum benzine. Norm al hexane is recommended for cleaning the adhesives used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause chemical damage to the polarizer. Wipe off saliva or water drops as soon as possible. Their long time con tact with polarizer Operating The spike noise causes the mis operation of circuits. It should be within the 200mV level (Over and under shoot voltage) Response time depends on the temperature.(In lower temperature, it becomes longer.) Brightness depends o n the temperature. (In lower temperature, it becomes lower.) And in lower temperature, response time(required time that brightness is stable after turned on) becomes longer. Be careful for condensation at sudden temperature change. Condensation makes damag e to polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur. When fixed patterns are displayed for a long time, remnant image is likely to occur. Module has high frequency circuits. Sufficient suppression to the el ectromagnetic interference shall be done by system manufacturers. Grounding and shielding methods may be important to minimized the interference Electrostatic Discharge Control Since a module is composed of electronic circuits, it is not strong to electros tatic discharge. Make certain that treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly. Strong Light Exposure Strong light exposure causes degradation of polarizer and color filter. Storage When storing modules as spares for a long time, the following precautions are necessary. Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature between 5 C and 35 C at normal humidity. The polarizer surface should no t come in contact with any other object. It is recommended that they be stored in the container in which they were shipped. Protection Film When the protection film is peeled off, static electricity is generated between the film and polarizer. This should be peeled off slowly and carefully by people who are electrically grounded and with well ion blown equipment or in such a condition, etc. The protection film is attached to the polarizer with a small amount of glue. If some stress is applied to rub the pro tection film against the polarizer during the time you peel off the film, the glue is apt tore main on the polarizer. Please carefully peel off the protection film without rubbing it against the polarizer. When the module with protection film attached is s tored for a long time, sometimes there remains a very small amount of glue still on the polarizer after the protection film is peeled off. You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is recognized, please w ipe them off with absorbent cotton waste or other soft material like chamois soaked with normal hexane. Transportation The LCD modules should be no falling and violent shocking during transportation, and also should avoid excessive press, water, damp and s unshine.
