TLV320AIC3254EVM-K: Level Detector value update cycle

Part Number: TLV320AIC3254EVM-K
Other Parts Discussed in Thread: TLV320AIC3254

Tool/software:

Hi.
We connected the components in DE as shown in the figure.
I'm reading the level detector (PeakSq_1 and Peak_1) values ​​with [Debug Probe Point], but the cycle is 0.5 seconds at the fastest.

Q1:
 Is there a way to check the data at a faster cycle (for example, 10 ms cycle)?
 Is it a good way to check the register data directly?

Q2:
 We can check the register address of level detector (PeakSq_1 and Peak_1) in [Component Interface Overview],
 but how fast is the register data update cycle (**ms)?
 For example, is it updated at about a 10 ms cycle?

    Hi,

    Do you need to use the registers for the level? Since this is sent out as digital, you can use external tool like audacity to get the level.

    Regards.

    Thank you for your reply.
    In one example,We need a register to check the volume level.

    We are developing a product using TLV320AIC3254.
    As shown, TLV320AIC3254(Slave) and MCU(Master) communicate via SPI (I2C).
    How can MCU get the volume data detected by [Level detector] of TLV320AIC3254?

    The memory data from the peak detect is updated based on the audio rate but reading it by MCU will depend on the I2C/SPI speed.

    You can speed it up with SPI instead of I2C.
