This LCD has been chosen specifically because it works well with the RasPiO®Duino. We’ve opened, tested and adjusted the contrast on every single one. We’ve also written someawesome “RasPi.TV-style” instructionsto guarantee you have a positive experience with your LCD.

There’s an open source library for driving this LCD from your RasPiO®Duino. I’ve written a demo-sketch to get you started. It operates the dual-sensor digital thermometer shown above, giving you the following output…

I’ve written 7 pages of instructions which have been appended to the RasPiO®Duino eBook. But you can also download just those last 7 pages if you choose to. Full instructions with high quality photos, diagrams, explanations and code walk-through are included. You can check those out any time you likehere…

The LCD has always been a device that acts as a window in human-computer interaction. For example, the prompt window on some instrument devices, the temperature and humidity prompt box, the device running status monitor, and the prompt screen of the counting device all have LCD figures.

ERM4004FS-1 is 40 characters wide,4 rows character lcd module,SPLC780C controller (Industry-standard HD44780 compatible controller),6800 4/8-bit parallel interface,single led backlight with white color included can be dimmed easily with a resistor or PWM,fstn-lcd positive,black text on the white color,high contrast,wide operating temperature range,wide view angle,rohs compliant,built in character set supports English/Japanese text, see the SPLC780C datasheet for the full character set.Optional 3.3v or 5v power supply and optional pin header connection.

It"s easily controlled by MCU such as 8051,PIC,AVR,ARDUINO,ARM and Raspberry Pi.It can be used in any embedded systems,industrial device,security,medical and hand-held equipment.

All the accessories listed below tier pricing need to pay.We won"t deliver until you select. Power adaptor should be 5V/2000mA in output and center pin for positive voltage and the outer shield for negative voltage .The temperature for controller RTD2660 would increase during working.That"s normal phenomenon,not quality problem.

ER-TFTV050A1-4 is 800x480 dots 5" color tft lcd module display with small HDMI signal driver board,optional 4-wire resistive touch panel with USB driver board and cable, optional capacitive touch panel with USB controller board and cable, optional remote control,superior display quality,super wide view angle.It can be used in any embedded systems,car,industrial device,security and hand-held equipment which requires display in high quality and colorful video. It"s also ideal for Raspberry PI by HDMI.

OpenLCD.write(128 + 20 + 9) is C code. In C the expression in the parenthesis is evaluated first. When the compiler sees that, it adds 128 to 20 to 9 which is 157. Then it sends 157 Dec to serial port. It sends just one byte, not three bytes one after the other.

The 20x4 character LCD module is designed to display letters, numbers, symbols, dot matrix. It can display 4 lines of 20 characters. Support 4-bit and 8-bit data transfer mode. Offers 5x7 matrix + cursor display mode. Providing display data buffer DDRAM, character generator CGROM and CGRAM. CGRAM can be used to store up to eight 5x8 dot matrix character font data graphic own definition. Provides a rich instruction set: clear display, cursor back to origin, display on / off, cursor on / off, display character blink, cursor shift, display shift and so on. It"s easily controlled by MCU such as 8051, PIC, AVR, ARDUINO, ARM and Raspberry Pi. It can be used in any embedded systems, industrial device, security, medical and hand-held equipment.
