Hi @schwghrt , Thank you for bringing this to our attention. You are correct, and the comment does not match the actual setting. We will work to get this updated and a new release out asap.
I'm curious, is your interest in this setting for the power savings? Wondering if you and/or most users were prefer the default to stay where it is, or move to the 2x50K setting?
'fast start', (whatever that is.)
I'm not entirely sure at this point, but I would guess that having lower resistor values would allow this VMID to energize/stabilize faster at startup. It looks like VMID is used a quite a few places, but if your system involves microphones using MICBIAS, then this could possibly effect how quickly your mics turn on.
Thanks again, Pete
My interest is really to make it work. One offered fast start, and the other one offered "playback/recording". It wasn't clear from the datasheet whether "fast start" was actually ok for "playback/recording". What else is there? I expect I'll be interested in power as the project gets farther down the road.
I realize this is the wrong thread, but I also split the L/R headphone gains. I want to use them as line out instead of headphones, and so I need split volume control. Easy change, but if you are making changes, it's a nice feature to have....
BTW, thank you for putting this library together. It simplified my project by orders of magnitude!!!
In order to enable VMID for playback/recording using the 2x 50k ohm voltage divider 8:7 should be 01 not 11. That is the 5k divider for 'fast start', (whatever that is.)
`// Enables VMID in the WM8960_REG_PWR_MGMT_2 register, and set's it to
// playback/record settings of 2*50Kohm.
boolean WM8960::enableVMID()
{
WM8960::_writeRegisterBit(WM8960_REG_PWR_MGMT_1, 8, 1);
return WM8960::_writeRegisterBit(WM8960_REG_PWR_MGMT_1, 7, 1);
}`
