Problem in LCD 16x2 I2C with MyRIO

[MaGenta_9]

Please anyone can help for program lcd i2c 16x2 using myrio because the demo on youtube i2c is different LCD, mine can't display with i2c myrio VI

In order to provide help for your LCD (which is different from the one used on YouTube), you should probably tell us what LCD model you want to use, and provide links to information on your chip.  Or you could just purchase the same LCD as the one you found on the YouTube video ...

Hello sir, for the reason I can't buy the same one as in the video because it costs too much, I use a 16x2 i2c lcd with the following specifications:

Features for 1602 LCD:
LCD display module with green blacklight.
Wide viewing angle and high contrast.
Built-in industry standard HD44780 equivalent LCD controller.
Commonly used in: copiers, fax machines, laser printers, industrial test equipment, networking equipment such as routers and
storage devices.
LCM type: Characters.
Can display 2-lines X 16-characters.
Voltage: 5V DC.

Features for 1602 LCD: LCD display module with blue blacklight. Wide viewing angle and high contrast. Built-in industry standard HD44780 equivalent LCD controller. Commonly used in: copiers, fax machines, laser printers, industrial test equipment, networking equipment such as routers and storage devices. LCM type: Characters. Can display 2-lines X 16-characters. Voltage: 5V DC. Tutorial I Watch

Again, you give no information about the hardware you purchased (which I assume is a 1602 LCD and an I2C chip that converts the multiple inputs on the LDC Chip to the 4 signals needed for I2C control.

As you know, the myRIO has functions that can easily be programmed to control devices using I2C.  All you need to know the the particular protocol your I2C device (the particular LCD 1602 I2C chip) requires.  Surely you have that information, so you should be able to use the myRIO's I2C capability to drive your display.

If you still need assistance, please provide easy-to-read information on the particular LDC 1602 I2C chip.  If you need help with the myRIO code (which you shouldn't), please provide a full set of LabVIEW Code that you've written.  I will not look at pictures from screen-shots which are largely unreadable, and (if LabVIEW code) don't allow close examination of the code.  The easiest way to generate such code is to right-click the folder containing the LabVIEW Project, choose "Send to" and choose "Compressed (zipped) folder" and attach the resulting folder.
