TFT 3.2" in 8 bit interface mode

[sairfan1]

Hi,

I have some TFT 3.2" (driver SSD1289, HX8352 and ILI9481) as these all have 16bit interface. after spending hours still i could not find out how can i interface it in 8 bit mode, in datasheet i read that it can be connected in 8 bit mode, but did not find any instruction or command. Please help if any one have tried it. thanks

Try interfacing the TFT in 8 bit mode using these drivers:

Thanks for reply, im working on SSD1298 for now, can you please advise when using in SPI 3pin mode which of the data pins are used for that?

You should read the datasheet. It shows you exactly which pins in Fig 6-2 on Page 25.

Table 5-2 has the pin names and their descriptions. (Note: WR serves as the SCL pin, see the description)

Thanks, the point where im stuck, is which pin acts as SPI interface in serial mode, TFT interface do not have serial interface, it has only 16bit Parallel interface, i believe some of data pins act as SPI interface in serial mode. Please refer to attached image of my TFT pins. Thanks. (there are also pins for Touch Panel and SD Card interface please ignore them)
