HY32D LCD and HY-Mini STM32V

I have a HY32D 3.2" TFT lcd with XPT2046 touch controller. I want to use it with mbed but I'm not sure of how to do that. Can anyone please guide me?

I also have a HY-Mini STM32V development board with the HY32D lcd. Can it be used with mbed? Can it's libraries be used?

Thanks

Hello moomal, if you mean this : http://www.hotmcu.com/32-touch-screen-tft-lcd-with-16-bit-parallel-interface-p-36.html

There is a port of my lib : https://mbed.org/users/frankvnk/code/SPI_TFT_ILI9320/ which support the controller used in this display, but the manufacturer of this board has configured the board to use the 16 bit parallel mode only. You can use this code as starting point and change the SPI routines to 16 bit parallel mode. You will need a lot of IO pins...

Thank you, Peter. I can start with this now.

I have found similar kind of TFT Touch Screen and its 16bit parallel code is available for mbed

It will give you some solid idea. He used the same BusOut command to access pins simultaneously

Note: Original author has deleted its code but you can still see the code by checking its old revisions
