Re: XK-AUDIO-216-MC free GPIO pins?
There are SCL and SDA solder rings on the MC board. I'd attach some headers for access. I'm considering this: https://www.tindie.com/products/arielnh56/high-resolution-absolute-encoder-128-positions/ It uses the TI PCF8574 which runs 3.3v and 100mhz max. Both the address ranges offered, 0x20 - 0x27 ...

Re: XK-AUDIO-216-MC free GPIO pins?
Thanks CousinItt,
after thinking about this a bit, it seems the best solution is to use the i2C bus and put an i2C enabled encoder on it.
There's a couple guys on Tindie that can provide a ready-made item.
Comments?

XK-AUDIO-216-MC free GPIO pins?
I have a XK-AUDIO-216-MC I'd like to add some HID devices, rotary controls, mostly. Am I correct that all the GPIO pins are already reserved for other functions? Any ideas for modifications to board to free up some inputs? I'm not planning to use the coaxial connections, for example. or could/should...

VendorLedRefresh() missing
When building 2i10o10xsxxxx_mix8, LEVEL_METER_LEDS = 1, for the XK-MC board, I get an error for missing function VendorLedRefresh(). Am I missing a library? And, in general, I'm clueless as how to use these defines and what they are supposed to do. LEVEL_METER_LEDS LEVEL_UPDATE_RATE LEVEL_METER_HOST...

Re: Addressing MC board LED's/GPIO Pins
I was able to successfully build a minimalistic project for playing with lights on the xk-audio-216-mc. #include <platform.h> #include <gpio.h> /* Buttons/switch port */ in port p_sw = on tile[1] : XS1_PORT_4B; /* LED grid port */ out port p_leds_row = on tile[1] : XS1_PORT_4C; out port p_leds_col =...

Addressing MC board LED's/GPIO Pins
Hi, trying to address the LED's on my XK-AUDIO-216-MC. ##################### Found this in gpio_access.h in the sw_usb_audio project, but no clue as how to use it. Bitwise operations? /*LED array defines*/ #define LED_ALL_ON 0xf00f #define LED_SQUARE_BIG 0x9009 #define LED_SQUARE_SML 0x6006 #define ...

xcore-200 Audio Headphones
Greetings,
I'm considering a XK-AUDIO-216-MC.
Can the outputs drive a set of headphones?
Or are these strictly line level?
I don't see the usual specs for impedance and sensitivity...
Thanks.
