hi Jeffres
the tools https://www.ti.com/tool/COEFFICIENT-CALC is not support tac5111, tac5111 require 32 bits filter coefficients for N0, N1, N2, D1, but the tool COEFFICIENT-CALC generate 16 bits filter coefficients .
and the support products from…
Hi Kawasaki-san,
This is feasible, but first-order LPF/HPF would be achieved by setting N2&D2 to zero.
You can use this tool and select LPF/HPF in "Type" and it will generate these coefficients: https://www.ti.com/tool/COEFFICIENT-CALC
Best,
…
Hi Rayna,
We have a filter coefficient calculator found here: https://www.ti.com/tool/COEFFICIENT-CALC
You can use it to configure first order filters for your application, it will output the coefficients to implement.
You can then program the values…
Hi Rob,
It is a little harder to deconstruct your coefficients for your filter, so instead I will explain my steps to get coefficients. First, you can use the TIBQ tool downloadable here: https://www.ti.com/tool/COEFFICIENT-CALC
This GUI allows you…
Hi Luo,
Page 0 Register 29 D3 controls loopback. ADC data will be used as DAC input, not I2S from MCU.
Your code also does not contain any EQ filtering. You must write the biquad coefficients you desire to the following registers
Adaptive filtering…
Hi Benoit,
Honestly I'm not the biggest fan of the AIC3204 EQ page. It's too hard to translate the results to register writes when you're not using an EVM.
I would instead use our TI Biquad Tool: https://www.ti.com/tool/COEFFICIENT-CALC
The software…
Hi,
I have an update here - you can download a TI biquad coefficient calculator tool here: https://www.ti.com/tool/COEFFICIENT-CALC
While it is not explicitly for this device, it can calculate coefficients for filters, and I was able to put in 24…
Hi Zhou,
The TI Biquad tool will allow you to determine the proper coefficients. https://www.ti.com/tool/COEFFICIENT-CALC Set your sample rate and then create your biquad frequency response that you want. Then click the "coefficient" button to see the…
Hi Sammy,
Unfortunately the bass and treble modes are exclusive, as they impact both Biquads 1 and 2. My recommendation is if you want more flexible control, use our TI Biquad tool to generate the coefficients and the load the values into the command…
Hi Zhou,
I investigated these errors and found that the PEQ part is bugged. Sadly because Purepath Studio has no active software support we cannot safely fix the bug.
My recommendation is to use the biquad blocks instead. You can use this biquad tool…
