Title: Arduino UNO interface with 3.2 inch TFT display in 16 bit parallel mode
Post by: rr_Bala on Mar 25, 2019, 03:27 pm
Hi Friends,

I have bought  Arduino UNO and  3.2" TFT display (320*240  ILI9341 driver -  model SKU MRB 3205) for my project.

Unfortunately the display not supports SPI or I2C  or 8-bit mode. It supports only 16 bit parallel mode but  UNO (ATmega 328)  have limited  IO pins .

Please share if you have experience on Arduino UNO  with 3.2 " TFT display in 16 bit parallel interface  or pls give your suggestions . Thanks in advance.

You appear to have bought a screen with this wiki (http://www.lcdwiki.com/3.2inch_16BIT_Module_ILI9341_SKU:MRB3205)

Although you can power the board with 5V or 3.3V it requires 3.3V GPIO on all the signals.    The 17x2 header does not match anything other than a STM32 dev board.

Either buy the STM32 dev board or buy a new screen.

David.
