TFT Display with Beagle Green
« on: January 02, 2019, 06:32:49 AM »
Hi,
We are using Beagle Bone green board. Using default(pre built Linux image) linux image on beagle bone green board. Linux Kernel booting on the board.
When i have connected NHD display "NHD-5.0-800480TF-ATXL#-CTP" and power On the board, board does not  boots  as the board LEDS are not blinking
And  no display on the NHD display.

The connection details between NHD display and beagle green board is attached:

Could you kindly suggest if i need to check any configuration or configuration change that enable LCD display on beagle green board
Thanks,
Aditya

Hello,

Our 5.0” TFT is a “raw pixel-dot-clock” display and does not have an SPI/parallel type controller or any kind of RAM.
The display is supposed to be constantly refreshed, at 60Hz, with a pixel clock, V sync, H sync, etc.
There are some high-end processors such as that used in the BeagleBone that can natively support such RGB TTL display.
You would also need an LED driver circuit to drive the backlight separately.

Please note we sell a 7.0” BeagleBone Black cape (NHD-7.0CTP-CAPE-L) it’s an open source hardware and the schematic is available for your reference, the pinout is similar to our 5” TFT.

Please view the links below:
