Hello,
we connected two ezdsp5535 boards via i2s and built two intercom units with a microphone and a speaker on each side. On software side we use i2s and dma to loop through the data. As example we hatd the beam form and usb audio demo code. We can talk in both directions and sound is good. Second step was to integrate aer/aec library. We did this similiary as in the aer demo code. Software runs, but audio is scrambled in one direction. We didn't execute quick tuning yet.
Questions:
- After opening aer instance, all parameters must be set explicitly through aerControl. Is this correct? When we don't call aerControl at all or leave out some values in the aerControl_s struct, we get an error.
- Do you have a set of default parameters with which we can start? At the moment we use the parameters from the aer demo application.
- When algorithms are turmed off, sound is good in both directions. When algos are active, sound is scrambled in one direction. Is this due to the fact that we didn't execute quick tuning yet?
- Reading back parameters from aer instance is not possible, right? So we must remember parameters externally.
Thanks in advance
Marc
