Hi,
I am working with Cyclone III Development Kit, 3C120 FPGA device, Quartus 9, and I am trying to program a simple audio loopback project using TLV320AIC23 audio codec, which is placed on HSMC data conversion board.
I used the HSMC reference manual pdf to find pin assignments to the audio codec through HSMC:
AD_SDIO - AD3
AIC_BCLK - AA12
AIC_DOUT - AB4
AIC_LRCOUT - AA3
AIC_SPI_CS - AB11
AIC_XCLK - AA4
However, there are 3 pin assignments that I could not locate in assignment editor:
AD_SCLK - AH1
AIC_DIN - W12
AIC_LRCIN - Y11
While trying to assign the pins to these locations, I got an error from Quartus: "can't recognize value PIN_<appropriate pin> as legal location".
As I have checked in pin planner for this device (3C120F780C7), the W12 location seems to be stucked to VCC, Y11 stucked to GND and AH1 does not exist at all.
Can somebody tell me the correct pin assignments that I should use to be able to work with the audio device?
Thanks!
