I would like to know if a specific HDMI driver board will work well with my display

Support

Hello.

Some time ago I’ve bought this display :

h t t p s : / / s h o p . pimoroni . com / p r o d u c t s / h y p e r p i x e l - 4 - s q u a r e ? variant = 30138251477075

I want use it with FreeBSD. The problem is that the driver has been written for Linux and it will never work for FreeBSD. But I’ve thought. I have only a chance. To find a compatible HDMI driver board. I’ve googled a little bit and I found this web page :

h t t p s : / / f o r u m . c o r e - e l e c t r o n i c s . c o m . a u / t /d r i v e r - b o a r d s - f o r - i p s - s c r e e n s / 1 2 0 6 3

at certain point,someone suggests that I can buy this adapter from Adafruit :

h t t p s : / / c o r e - e l e c t r o n i c s . c o m . a u / t f p 4 0 1 - h d m i - d v i - d e c o d e r - t o - 4 0 - p i n - t t l - b r e a k o u t - w i t h o u t - t o u c h . h t m l

I would like to know if it is compatible with my hyperpixel 4 square touch display. If it is not,can u suggest one that it is ?

Maybe you need to give a look at this tech specs to understand :

h t t p s : / / p i n o u t . x y z / p i n o u t / h y p e r p i x e l

thanks.

I don’t think you are on the right track. HDMI is a serial interface, and the hyperpixel has a high-speed parallel interface.

One thing to try: before there was Linux kernel support, there was a non-kernel level driver. Maybe this is easier to port to BSD?! But maybe my memory is wrong, and it only was an out-of-tree driver.

For me not. It’s the most difficult thing to do. My job is the psychologist. Computer science,electronic are only my hobbies.
