I'm trying to figure out how to interface with the LCD controller on the STM32373C-EVAL board. The driver code I downloaded from the keil.com queries the chip for an ID and checks to see if the chip is an ILI9328 or a HX8347, but neither ID matches. The ID returned from reg 0 of the chip is 0x9595. Is there any way I can find out what chip this is?
The LCD daughterboard is fixed flush to the eval board so I can't just flip it over to read the part number on the chip itself. I'd rather not write my own initialization and interface drivers for a chip, but if I have to, then finding a datasheet for the part I'm trying to interface with is the first step.

Try building the ST examples for the board in the CubeF3 package.

Thanks for the tip, but it looks like it uses the same LCD driver code as the samples I've downloaded. Unfortunately, it doesn't get me any closer to getting the LCD working or even figuring out what component is on the board.
