This item is made and shipped from Canada, sorry can't be combined with other items Item Description Shipping Return/Warranty Payment About us FAQ Description If you need large quantity of this item, please contact us in advance Sale is for 1 pieces of: 2nd Version-Serial: UART/I2C/SPI Text LCD Display Adapter for 1602/1602/2002/2004/4002 LCD Backlight be controlled able by software (This auction EXCLUDE LCD panel in pictures below) (Please compare the pinout with you display, make sure they are same before purchasing) Unlike other "Serial Display" which just convert serial input to parallel, Digole's Serial displays and adapters embedded a powerful MCU to process the commands received. Display characters and control back light as you want, all commands are simple, high level and easy to remember! Programing User Manual Download Arduino lib and demo code mbed Library (Thanks for Michael Shimniok to contribute code) The following vedio show this adapter work with 16pin and 8*2pin LCD In order to use a Text LCD display, you need connect at least 4 data pins and 2 control pins from your circuit to display, and you also need to spend some time to write code to drive it, in some case, you may need couple of days to deal with it, and it will give you a nightmare when changing to other display. This control module (adapter) will help you to solve this issue, it can work with most 1602/1604/2002/2004/4002 LCD that config with KS0066U/F / HD44780 and other compatible chips seamlessly, so you can use your display with this module in couple of minutes!(Please ask if you not sure whether or not your LCD is compatible with the adapter) What benefits you if using these products in you electronic projects? Save lots of the I/O resources: these products only need 1 to 3 I/O pins from your master controller that depends on the communication type you want. Easy to use: the commands sending to products are easy to remember and understand. FEATURES: Supply voltage: 1.8V to 5.5V Communication mode: UART/I2C/SPI, defined by the jumper on board Receiving buffer: 64 bytes Work with KS0066U/F / HD44780 and other compatible chips Work with most 1602/1604/2002/2004/4002 LCD 16/20 Pins with 2.54mm pitch connect to LCD Low power consumption: 4mA maximum Simple command sets, easy to remember Default setting: UART baud 9600bps, I2C address is 0x27 UART baud (bps): 300, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, 115200, selected by software Manual, Arduino lib, sample code download here Turn backlight on/off by software to save energy Work with 2002 LCD (double row 8x2 pin) Work on 1602 LCD (single row 16pin) Pinout of module connect to LCD display: PIN Description PIN Description 1 VSS Ground of circuit 2 VDD Power Supply 3 V0 4 RS 5 R/W 6 E 7 DB0 or D0 8 DB1 or D1 9 DB2 or D2 10 DB3 or D3 11 DB4 or D4 12 DB5 or D5 13 DB6 or D6 14 DB7 or D7 15 BLA or A, + power supply for backlit 16 BLK or K, - power supply for backlit Pinout of this module connect to MCU: PIN Description PIN Description 1 GND (0V) 2 SS: SPI mode only chip select control in, low active 3 I2C and SPI mode: SCK/SCL: Clock in 4 UART mode: RX I2C mode: SDA SPI mode: SDI 5 VCC: power supply 1.8V to 5.5V depends on you LCD Character/Graphic Display Shared Command: (B-one byte, B…-Bytes) Command Description Arduino lib function note CL CLear screen and set the display position to first Column and first Row (x=0.y=0), for graphic LCD, it also set the font to default and turn off the cursor. clearScreen(); CSB set CurSor on/off enableCursor(); disableCursor(); BLB Set Back Light ON/OFF, B=0 or 1, 0 off, 1 on backLightOn(); backLightOff(); Not available on Character Adapter V1 DCB Display Config on/off, the factory default set is on, so, when the module is powered up, it will display current communication mode on LCD, after you design finished, you can turn it off displayConfig(0); displayConfig(1); SBB… Set UART Baud, B are ASCII characters, the available values are: “300”, “1200”, “2400”,”4800”, “9600”, “14400”, “19200”, “28800”, “38400”, “57600”,”115200” Set BAUD when initial the class When adapter power up or reset, always start with 9600 Baud SI2CAB Set I2C Address,the default address is 0x27, the adapter will store the new address in memory setI2CAddress(0x34); Change address to 0x34 STCRBBBBBB Set Text Columns and Rows, this command will config your LCD if other than 1602 and the chip is other than KS0066U/F / HD44780 setLCDColRow(20,4); The last 4 B should be“\x80\xC0\x94\xD4” TPBB set Text Position for following display setPrintPos(6,1); This will affect the following “TT” command TTB… display TexT string, the text will wraped in next row if the current row fulled, the Text Postion will be changed to the last char displyed, this command ended by 0x00 or 0x0D received print(string); print(int); print(char); print(float); print(double); drawStr(x,y,string); The print function in Arduino, also can print other data and format the out put.
