I am trying to interface SPI to display LCD using GUIX.
1. All init is OK no Error
2. Without GUIX Display is OK
with GUIX initialization of LCD Display is apparently OK, But Display is not working.
Using Oscilloscope I have further checked that when init happens (for LCD Display) I am getting pulse for SPI Bus , but further nothing is displayed.
After init no pulse can be seen on Oscilloscope.
Please feel free to ask for any additional information.
Can you tell us what status is being returned on the SPI write calls? Does it indicate an error, or does it say the write was OK?
Please let us know if this is still an issue for you or if you found a solution on your own.
Looks like you must have found a solution on your own after checking status.
It seems like no one responded yet to this post. Have you made any progress so far? I think it might help other members too if you're gonna mention what specific LCD are you trying to interface with the S7G2.

Thank You for replying.
We are using a 320x240 pixel TFT LCD display (make: New Heaven)
Init is OK as per LCD, But read and write to LCD using SPI is not working.
No signal output from SPI after initialization is done.
This issue was dropped from our end and is still as is.
Currently I am busy with our Web-Server module.
For now lets keep this issue closed, I will get back on this with a fresh post if need be.
