Just paid my deposit, excited!
My plan is to primarily use 16n to interface with the ER-301 over i2c. So, planning ahead and thinking out loud, I figured it would be worth sharing the steps to get 16n working with ER-301 as far as I understand them.
From the post that @jasonw22 shared, it sounds like a TXb isn’t required if the only thing I’m connecting from the 16n is the ER-301, I could just make a cable that goes direct from one to the other, correct?
My module is pre the i2c port fix so I’ll first have to follow these instructions to solder the shunt:
After that I’d have to make own cable. The above post shows the labelling of the pins on the ER-301 and according to this page here’s the wiring of the 3.5mm stereo jack on the 16n:
Sleeve: GND (ground)
Given what it says there, if the ER-301 is the only thing connected directly with that cable from the 16n it shouldn’t require a powered bus or the pull-up resistors, correct?
Other than firmware tweaks, am I missing anything?
