void gb.tft.sendBuffer( uint16_t* buffer , uint16_t n )
gb.tft.sendBuffer starts a DMA transaction to send a buffer of the size n. You have to check extern bool Gamebuino_Meta::transfer_is_done to check if the transfer is done.
Parameters
uint16_t* buffer: buffer to send
uint16_t n: size of the word-buffer (Important! NOT bytes!)
