Hi,
I'm currently working on a project with the MIMXRT1176-EVKB. In this project, I would like to display some screens on the RVT70HSTNWC00-B display and be able to register touch coordinates.
I already have a working screen thanks to another NXP forum post: https://community.nxp.com/t5/i-MX-Processors/Creating-a-driver-for-a-MIPI-LCD/m-p/1772322
The only issue I have is that the touch driver (ILI2132A) for this display works slightly differently than other drivers (e.g., the GT911) but still uses I²C as protocol and there are no examples in the SDK that use this driver.
Does anyone have a solution for this that can be built on the MIMXRT1170 series?
All help and information are welcome.
Thanks in advance!
Hi @KobeV,
We do not currently provide a proper driver for the ILI2132A, but the RT1170-EVKB does support Zephyr, which has a driver for this touch IC called "input_ili2132a.c" (Doc, GitHub).
Considering that the specifics for the ILI2132A touch IC are already implemented on that driver, the migration process to a bare metal driver is quite achievable. All the GPIO and I2C functions that are using on that driver should already have their bare metal equivalent on our SDK, so I suggest migrating or create your own driver based on that one.
Also, since the RT1170-EVKB is already supported by Zephyr, you could do testing scenarios with a Zephyr-based projects to ensure the functionality of the driver and debug its functionality before any migration process.
BR,
Edwin.
