TGFX bug if you change mode setup (ltdc - custom, single - partial ...) delete target folder before generate code.

I dont test latest but my old partial project is generated with this info in target cpp file

#error "A user must call touchgfx::startNewTransfer(); once touchgfxDisplayDriverTransmitBlock() has succesfully sent a block."
#error "A user must implement C-methods touchgfxDisplayDriverTransmitActive() and touchgfxDisplayDriverTransmitBlock() used by the Partial Framebuffer Strategy."

You need do what is writed and after implement comment this lines out.
