64x64 RGB LED Matrix - 2.5mm Pitch - 1/32 Scan not working

Post by sugan_09 »

This is regarding the 64x64 RGB LED Matrix kit (PID:3649) that I purchased from Adafruit.
The order number is #2694790-8342651276.

When I tried connecting the display kit to my microcontroller board and power supply , I found that one half of the board is always completely lit up and displays different colors which can be seen in the screenshot I have attached.

For your reference , I am using a 5V and a 4A power adapter for this kit .
Could you please let me know what could be this issue and how to resolve it?

What are you using to drive the matrix display?

I am using LPC4078 microcontroller to drive the display. I tried to power up the matrix display using 5V 4A power adapter. And observed that the upper half of the display lit up and produced random colors.

We don't have any support for usage with a LPC4078. Any form of bare wire connections to the matrix itself are also not recommended or supported:

Is the LPC4078 the only device you have available to drive the RGB matrix?
