Dear,
I recently upgraded my project from NCS 2.4.0 to NCS 2.9.0 and encountered an issue with the ST7789V display driver.
Previously, I used SPI0 to interface with the ST7789V display, and the configuration in my device tree worked fine. However, after upgrading to NCS 2.9.0, I noticed that the driver type for ST7789V has changed to MIPI-DBI, and my previous device tree configuration is no longer applicable.
I have reviewed the nRF Connect SDK documentation, but I could not find any clear guidance on how to correctly configure MIPI-DBI for ST7789V in the new version. Below is my previous device tree configuration that worked in NCS 2.4.0:
Could you please advise on:
- How to correctly configure the device tree for ST7789V using MIPI-DBI in NCS 2.9.0?
- Are there any specific changes in the SPI or display subsystem that I need to consider?
- Is there an example or reference documentation available for migrating from the old driver to the new one?
I appreciate your support and look forward to your guidance.
Best regards,
