I haven't had the time to experiment with the latched 8-bit bus version but can confirm that the SPI interface and the sainsmart32fb driver are a working combination with that display.notro wrote:I got a message a week ago from @xtramural that he got his ITDB02-3.2S working with the SPI interface circuit and the sainsmart32fb driver.
He was looking into driving it with a latched 8-bit bus, but I don't know if he has succeeded with that.

Code: Select all
case HX8352A: LCD_Write_COM_DATA(0x02,x1>>8); LCD_Write_COM_DATA(0x03,x1); LCD_Write_COM_DATA(0x04,x2>>8); LCD_Write_COM_DATA(0x05,x2); LCD_Write_COM_DATA(0x06,y1>>8); LCD_Write_COM_DATA(0x07,y1); LCD_Write_COM_DATA(0x08,y2>>8); LCD_Write_COM_DATA(0x09,y2); LCD_Write_COM(0x22); break;
This should not be an issue, the controller does support 8/16 bit parallel interface with the usual 4 bit data control. Unless i misunderstood something that should be exactly what the other controllers use aswell.notro wrote: Another issue the driver has to handle is the interface used by the display module.
* 8-bit SPI
* 9-bit SPI
* 8-bit parallel
* 16-bit parallel (this is not tested yet)
