How to redefine the ports for alt Diamond (usb slice)? Topic is solved

[sharpeye]

I have the xmos usb slice kit (u16) and the audio slice if i follow the compatibility matrix it should be possible to combine the audio slice with the core board.  this should be done through use of the alt diamond.

I want to test it with the examples, (start with biquad) as I have looked through the datasheets and could not find why in app_global the ports are named XS1_ PORT_1A or something in that way. as in topic suggested i have used the redefined portmap, but this did not work. So if I know why they are named the way they are I can determine witch port is witch pin.

As a second part of my question should I alter a other part of the example to get it to work?

 

in short: how do i get the audio examples to work if i use the usb slice core board in combination with audio slice?

I found the solution, the documentation is wrong (at least for the audio slice 1v1) the correct pinning can be found in the schematic.

only change the port defines to

Code: Select all

	#define PORT_I2S_DAC0      XS1_PORT_1D
	#define PORT_I2S_DAC1      XS1_PORT_1H
	#define PORT_I2S_ADC0      XS1_PORT_1K
	#define PORT_I2S_ADC1      XS1_PORT_1L
	#define PORT_I2S_LRCLK     XS1_PORT_1I
	#define PORT_I2S_BCLK      XS1_PORT_1A
	#define PORT_MCLK_IN       XS1_PORT_1E
	
	#define PORT_GPIO          XS1_PORT_32A
	#define PORT_I2C           XS1_PORT_4E

and it should work. I hope this helps you as well.
