Description
Hello Guys,
I am using the lvgl_demo_widgets example that came with the MCUXpresso IDE and this 7" display from Riverdi. I have designed a bridge from the 40pin to the 50pin required for the RGB and the same for the capacitive touch signals.
What MCU/Processor/Board and compiler are you using?
I.MXRT1050-EVKB
What LVGL version are you using?
LVGL 8.0.2
What do you want to achieve?
I would like to achieve the touch controls working properly.
What have you tried so far?
I have tried adding the lv_drivers to my project and setting USE_FT5406EE8 to 1 in the lv_drv_conf.h
