Hi,

Unfortunately, we do not have any sample code available for the C8051F380 microcontroller. However, we do have sample code for the Arduino Uno that you can use as a reference for your code development. Please note that this shared code can also be used for the NHD-0216KZW-AB5, as it shares the same timing values, command table, and initialization sequence.

Is the code the same for NHD-0216CW-AB3

is this NHD-0216CW-AB3 display compatible with the C8051F380 microcontroller please let me know and share the SPI code for this NHD-0216CW-AB3.

Hi,

The code for the NHD-0216KZW-AB5 differs from that of the NHD-0216CW-AB3 due to variations in pin connections, timing characteristics, and commands. Please refer the sample code written for the NHD-0216CW-AB3 display on the Arduino Mega. However, we have not yet tested these displays with the C8051F380 microcontroller to ensure compatibility.

Is there any method to verify whether this NHD-0216CW-AB3 Display is compatible with the C8051F380 microcontroller or not? Please replay to me on an urgent basis.

This Code fully works with the NHD-0216KZW-AB5 display with Arduino Uno Please give a sample code for NHD-0216CW-AB3 with Arduino Uno( We don't have Arduino mega).

Hi,

Unfortunately, we do not currently have a sample code specifically available for the Arduino Uno. However, you can still utilize our available sample code and adapt it for use with the Arduino Uno by adjusting the pin configurations.

Hi,

Unfortunately, we do not have any sample code available for specific applications. Typically, we provide sample codes to our users to help them set up the display. However, they will need to implement the code to fit their specific application. If you are interested, you can search for a sample code online that demonstrates how to display sensor values.
