Questions for VS1053b/VS1063a Equalizer ver1.50

Post by Jaehoon » Fri 2016-03-11 13:52

Hello VLSI,

I just changed the vs1053b_vs1063a_equ code from ver1.30 to ver1.50 on my device.
I could hear microphone sound at ver1.30 but I couldn't hear microphone sound at ver1.50.
Could you let me know how could I change my code for ver1.50 if I missed instruction guide?

I have one more question. The ver1.50 supports Sine Generator.
Could you let me know how could I start or stop the Sine Generator after Start setting filters?

Thanks,
Jaehoon.

Do I understand correctly that you use a microcontroller to load the .plg version using SPI?

Do you only have a problem with the Microphone Input? Does Line Input work? Or don't you get any sound?

To start the Sine Generator, see instruction Chapter 7.1, Sine Generator. For example, if you want to create a 1 kHz sine wave, write 171 (0x00ab) to SCI register SCI_AICTRL2. To disable the sine wave generator (and to resume normal audio), write 0 to SCI_AICTRL2.

If you want to, you can set the filters before running the sine generator. You can also modify the filters while running the sine generator.

Kind regards,
