LCD 16207 pins on Cyclone V Soc Dev Kit

Hello everyone,

I am trying to use the included Optrex 16207 LCD display of my board (Cyclone V SoC Dev. kit with a 5CSXFC6D6F31C8NES chip).

My problem is that I can't find anywhere the coresponding pins to the outputs of the controller core IP (E, RS, R/W and DB0 to DB7). The reference manual of the board does not contain this information and I couldn't find it anywhere.

Does anyone have a complete pin corespondance sheet for this board, or at least for these particular pins?

Thanks.

    It looks like the LCD on that development kit is accessed via I2C and not directly using the standard set of signals you list. Looking at the schematic for the board there is no mention of LCD except via header J15 (a 1x10 way header) referred to as the LCD_HEADER. This only has power and I2C going to it. It also refers to the I2C address of the LCD as 0x50.

    So, I doesn't look like you have direct access from the FPGA to the E, RS, R/W and data pins of the LCD.

    Regards,
