Dear all, |
I have a question. |
A customer asked us the problem how to set GPIO2 output of PCM5142EVM by using Pure Path Studio(PPS). |
His setthing is as follows, |
1.software:PPS |
2.EVM:PCM5142EVM |
3.Load PCM5120_SPDIF_ROM_OPTICAL.pfw |
4.Check analog Output, but cannot check GPIO2 |
Then a customer make process flow as follows |
5.Firm ware :PCM5142App_1 |
6.Input:I2S_In_1 |
7.Output:GPIO_Output_1 & Int2xOutROM_1 |
8.Volume connecting between input & ouput |
9.generate and download |
Using I2C Memory Tool (Direct control GPIO2) |
11.set GPIO2 Output(register 8,data 02) |
12.set GPIO2 to SDOUT(register 51,data 07) |
Question1:How to make the output of GPIO2in SDOUT? |
Question2:How to switch (Optical, Coaxial, USB) input of EVM in the process flow of new? It does not change that it is not made to read in advance the ROM code (PCM5120_SPDIF_ROM_OPTICAL.pfw etc,) now. |
