Hitachi TX0705APAA5 TFT interface board

Other Hardware Displays

I'm working with Hitachi TX0705APAA5 TFT touch screen dispaly. I want to design a board to control and interfacing device to external system based on microcontroller or DPS.

I thought to

  • set IM0, IM2, IM3 pin of TFT device, to 111 (4 wire SPI mode)

  • use ILI9486L (or similar) to drive graphic interface in TX0705APAA5

  • connect the IC's out DB[17:0] to digital input DB[17:0] (pin 10 - 27)

I should connect Hitachi TFT with 39 way flat cable, so I have found out this Flexible Printed Circuit Connectors:

I would be interested in hearing your views on these matters.

It appears to be a 240x320 panel for a mobile phone.

If you want help, please provide a link to a datasheet.

Yes, if you have access to the IM# pins, you can use whichever interface you want.
4-wire SPI is a wise choice. Remember that 3.3V panels require level converters for the logic.

By the time that you have wired level converters, ribbon connectors, ... to the Arduino it would have been easier to plug a ready-made Shield onto your Uno, Mega, Zero, Due, ...

Many thanks for your reply.

Sorry. but I can't find the specific datasheet for this display. I have found this https://wholesaler.alibaba.com/product-detail/3-5-inch-tft-320x480-touch_60168848805.html.
It seems to be like mine. It have the same dimension and pins number.

Can you suggest me other IC interface to TFT?
ILI9486L is not readily available.

Level converters is required because of TTL out of Arduino (i.e. 0 - 5V in Atmega uController)?

I suggest that you buy a ready-made Shield.
Then we can advise which libraries are suitable.

If you want technical help, you need to provide technical informatiom e.g. the actual datasheet
