This module can be controlled by the host with three control signals, SEL, SLK, SDATA. 2.3. Since a DC/DC converter is used. Power source (5Vdc) is required to operate the module. 2.4. Characters are provided with a 5*7 dot matrix. 2.5. This module has 200 characters in Build-in character generator. The user definable fonts(UDF) can be programable up to 8 characters. 3.

Command Description: X : Don’t care * : Selection bits “0” : Low – level “1” : High – level There is no 0xF6 function to set digit scan time, If a command undefined sends to the module, there will nothing happens. 4.1.1. Set: display lengh: 4.1.2. Set digit dimmer value: 4.1.3. Set digit point: 4.1.4. Auto increment mode ON/OFF: 4.1.5. Display all ON/OFF: 4.1.6. Storing data in UDF: The following 3steps define UDF to RA1~RA8 The 1st. is the declaration to degine UDF. (1 byte command) The 2nd. Is the selection of a UDF character code number.(1 byte command) And the 3rd. is the data set of the font.(5 byte command) Therefore, to design user font to UDF, continuous cp,,amds of 7 bytes are need. The UDF character code of RA1 TO RA8 are assigned to 00(Hex) to 07(Hex). 4.2. Scan Timing Description 4.2.1 Set display length This command sets the display length. For example,if 12digit selected,13~16digita are always OFF. 4.2.2. Display scan timing T=4.096ms Tdsp=256us Tdig=240us Tblk=16us 4.2.3.Character Display Operation 4.2.4.Character Display Operation 4.3.Initialization The power on reset function allows the users to re-initialize the display controller, after the power is turned off and then power on. When the controller is initialized, the display status is given below 1. Address of each RAM : Address “00”H 2. Data of each RAM : All contents are undefined 3. Display Digit : 16 Digits 4. All Display Light : OFF Mode 5. Segment Output : All Segment Outputs are set to “LOW” 6. Digit Dimmer Value : 8/16 4.4. Timing chart 4.4.1 Data write timing The data shall be written fromD7(MSB) to D0(LSB). The data is fetched when the Serial clock goes from Low to High. 4.4.2 Busy timing This shows the internal operation time after receiving the serial data. Next data is prohibited in this period. Next data is available after 6T of the operation clock (about 500~4000ns) 4.4. Recommend Initial setting sequence After reset, the module must be set according to the Initial Setting Flowchart shown below. 4.5 Font Table
