- Communication mode: UART/I2C/SPI, detect your setting automatically
- Receiving buffer: 2048 bytes
- Work with all microcontroller and microprocessor
- Communication signal can work on 3.3V and 5.0V TTL
- Default setting: UART baud 9600bps, I2C 0x27 address
- UART baud (bps): 300, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, 115200, 230400, 460800.
- 2MB on board flash chip, provide huge memory space to save user fonts, user data and pictures
|
- Pixels: 320xRGBx240, 262K colors
- View Area:30.7x40.8mm
- Screen size: 36.7x51.2mm
- Product size: (WxHxD):36.7x62.5x5.4mm
- Simple command sets, easy to remember
- Simple graphic engine integrated
- 7 preloaded fonts, font’s data structure full compatible with U8Glib
- Commands Backward compatible with mono Digole serial display, replace other Digole serial display seamless.
- Special commands to set color and draw color image, you can display 256 color image with 262K true color image on same screen.

Design the interface on this display by using Digole's online emulator in few minutes(https://www.digole.com/digole-emu.php)
HIGHLIGHT FUTURE:
- Works with 2.7V/3.3V/5.0V logic systems, 4bit/8bit/16bit/32bit micro-controllers. it EVEN works stand-alone.
-
Support serial (Hardware or Software): UART, I2C and SPI, set by the jumpers on PCB, support all four SPI mo.
-
7 fonts and graphic engine embedded, touch screen and flash chip drivers embedded(if touch screen or 2 to 16MB flash chip installed), custom fonts can be downloaded to the module's flash.
-
Firmware upgrade-able and custom-able: Visit Digole's firmware upgrade page.
-
High level commands set (61 commands total) are easy to remember and understand, eg.: send 5 bytes: "CCabc" will draw a ratio=c pixels circle at coordinate (a,b) on the screen; 5 bytes "DNALL" will put the module to sleep mode(<0.1mA), and more...

// Communication set up command
* "SB":Baud (ascII bytes end with 0x00/0x0A/0x0D) -- set UART Baud Rate
* "SI2CA":Address(1 byte <127) -- Set I2C address, default address is:0x27
* "DC":1/0(1byte) -- set config display on/off, if set to 1, displayer will display current commucation setting when power on
// Text Function command
* "CL": -- Clear screen--OK
* "CS":1/0 (1 byte)-- Cursor on/off
* "TP":x(1 byte) y(1 byte) -- set text position
* "TT":string(bytes) end with 0x00/0x0A/0x0D -- display string under regular mode
// Graphic function command
* "GP":x(1byte) y(1byte) -- set current graphic position
* "DM":"C/!/~/&/|/^"(ASCII 1byte) -- set drawing mode--C="Copy",! and ~ = "Not", & = "And", | = "Or", ^ = "Xor"
* "SC":1/0 (1byte) -- set draw color--only 1 and 0
* "LN":x0(1byte) y0(1byte) x1(1byte) y2(1byte)--draw line from x0,y0 to x1,y1,set new pot to x1,y1
* "LT":x(1byte) y(1byte) -- draw line from current pos to x,y
* "CC":x(1byte) y(1byte) ratio(byte) -- draw circle at x,y with ratio
* "DP":x(1byte) y(1byte) Color(1byte) -- draw a pixel--OK
* "DR":x0(1byte) y0(1byte) x1(1byte) y2(1byte)--draw rectangle, top-left:x0,y0; right-bottom:x1,y1
* "FR":x0(1byte) y0(1byte) x1(1byte) y2(1byte)--draw filled rectangle, top-left:x0,y0; right-bottom:x1,y1
