GUIX sample code with I2C interface for NXP Controller

Question

I am using NXP S32K148 controller. on the board i also have UG-2864KSWLG01 display IC. I use NXP to communicate with the Display.
the display is 128 x 64 Dot Matrix OLED/PLED Segment/Common Driver with Controller. I wanted to use Azure GUIX for Display.
Can any one share sample code for Azure GUIX which uses I2C module for communication.
If any sample code also there will be helpful.

Answer 1

For this type of architecture, we would normally recommend that you configure a local buffer for the GUIX canvas memory, and provide a buffer-toggle function that transfers the modified portion of the local canvas memory over I2C to the display after each drawing sequence. If you can send email to azure-rtos-support@microsoft.com, I can send you a template monochrome GUIX display driver that should help you implement this solution.

Regarding the I2C interface specifics, I'm not sure we have that particular board in-house. I would leverage the bsp and examples provided by NXP to implement the memory-to-display graphic data transfer.

Hi Ken,
Thanks for the reply. The answer gave me some idea how to use it. I will go through the template file you have shared and go through and get back to you if i have any questions.
I have already created low level I2C interface which can get data from Canvas, and write to display the data coming from Canvas.
