Support for RMRM68130 #1266

Closed mininmobile closed 3 years ago

mininmobile commented 3 years ago

i see there already is RM68140 support, i'm sure adding support for the RM68130 shouldn't be too bad?

i might try to do this myself to see if i can get it to work but it is unlikely since i am unexperienced to say the least :p

i have found a version of utft which supports this display -- unfortunately i cannot use it with esp. here are the init codes it has which could be useful to someone who knows what they're doing

// initlcd.h
case RM68130:
        delay(50);

Unfortunately I do not have the free time at the moment to add support other display variants. These RM68140 displays do not seem to be commonly available ready mounted on easy to use PCBs either.
