Dps fullily working now?
I'm just processing all the samples in the
Buffer in one go because I'm applying the same effect to both left and right channel.
I change to interleaved in case I need stereo fx.
It turns out my mono problem is a hardware fault or possibly a firmware that needs updating.
I convinced myself stereo pass through was working at one point but I had only enabled the direct line input to output feature of the codec.
If I just flash basic pass through example either mic or line, channel 1 inputs on ADC (mic) or channel 2 inputs on ADC (line aux connector) I get a mix of both channels.
I have another lyrat 4.3 board in the post so I'll check that soon as I arrives.
I flashed the esp32 to latest bootloader firmware but did'nt help.
I the lyrat 4.3 manual it shows 3 other bin files at diffent address and so far I have no idea what they are. I better start a new post for that.
So anyway, a massive thanks for you help / interest.
The original equalizer.c element input / output samples buffer is set to 100 length , seams like an odd number
So far I have to say I'm impressed with the lyrat Esp-adf / esp32 framework.
OK going to post some firmware questions before I assume the board is defective but its looking like it might be.
