Re: how to initialize array of 'pins' using multi pin ports

Fabriceo, Thank-you for all of the feedback. To output on 4 pin port for DAC, I had essentially modified audio loop in audiohub, as you described. Just for the DAC first. I'm currently outputting a fixed pattern for DAC I2S data outputs. I'm still inputting from ADC, just ignoring data for now. I'm ...

Re: how to initialize array of 'pins' using multi pin ports

I've looked further into at using a 4-bit port for Audio Out, which requires Using the required zip operation. For obvious reasons, The audio loop execution time has increased. As the loop time increases, I see a shift between the I2S Data being clocked out AND LRCLK edges. I’ve been able to adjust ...

how to initialize array of 'pins' using multi pin ports

Hi, I show below,  one way to initialize the array p_i2s_dac [] using eight (1) pin ports.    How should the initialization change, when using two (4) pin ports; Here is how it is handled when using eight (1) bit ports /* from XN file */ Port Location="XS1_PORT_1P" Name="PORT_I2S_DAC0...

Re: I2C on two different Tiles

Okay, thanks for all the feedback. I believe that I have two options: Option A : Use one I2C server (Master Synchronous server with 2 clients): Server will be loaded on Tile 0, and will use i2c_sda and i2c_sda pins also on on Tile 0. There will be one client on Tile 0 and one client on Tile 1. Both ...

Re: Create Xmos Resource Map File from within XTC command prompt

I think the -report option displays the available and the used resources on each tile. Just the numbers of timers, chanends, memory and cores used on each tile. I was more interested in getting all the specific details for those resources. The names of the chanend and cores specifically. I would the...
