Hello All,
I al looking for information on the USB class of the 5" vocore screen. I am in design on a project creating a road course/formula style sim racing wheel. I want to get away from using a corded connection... I need to be able to do a USB passthrough with either an ESP32 chip or another bluetooth or wifi chip so i can connect the USBc to the steering wheels PCB board and have it. transmitt thru either bluetooth or wifi. Any and all help is appreciated. If you need more information please let me know and ill will provide what i can. Thanks all in advance.

Re: 5" VOCORE SCREEN USB CLASS
Currently screen only support USB.
Bluetooth problem is its bandwidth is very narrow that caused it is too slow to swap different pages.
Wifi problem is latancy is very high compare to USB, might not good for Simrace which require low latancy.
Both ways will need optimization and still might not as good as USB.

Re: 5" VOCORE SCREEN USB CLASS
Might I suggest that instead of trying to pass information for the video image over BT, you instead receive the telemetry data over BT and use that to render whatever you want on the screen using your chosen dev board. I know this is more work, but you will have an ultimate solution which would be valuable to many others.
I suppose the question which needs answering is can we use the MPRO in slave mode to receive data from our chosen platform.
I am entirely sure the VoCore2 would work but the boot times may be an irritation.
Vonger, can we connect to the MPRO i2c and control it? A single app device like an ESP32 would boot far quicker and make for an excellent experience.

Re: 5" VOCORE SCREEN USB CLASS
This is exactly what we are working on.
Currently we make MPRO support run application, such as LVGL in memory or save to firmware, new MPRO have approx 480KB free space, with compress can store pretty complex UI.
So user can upload different applications(or dashboard) as a LVGL application, then we open UART/I2C/USB/TOUCH API, so LVGL can read and white with the three interfaces for different usage.
