Re: Using ESP8266/32 to write Flash
Hmm, well you can of course hold xmos in reset and directly control the QSPI lines but you will need QPSI support (at least bit banged) in the ESP and also you need to be wary of SI with stubs on the lines (particularly clock). Alternatively you could use the flashlib API under say, slave i2c contr...

Re: i2c control specification for vocalfusion
Thanks, I have seen these documents and they don't answer the question I've asked.
Not to worry though, I think I've found a way to get through.
Thanks!

Re: i2c control specification for vocalfusion
Sorry it looks like I'm just having one of those days where I can't see the wood for the trees. It seems to be that the structure is as follows: 8 bits 8 bits 8 bits 32 bits 32 bits 32 bits Resource ID Command (R/W) data length Parameter ID Parameter Value Parameter type (0:Float, 1:Int, 2:NA) Does ...

i2c control specification for vocalfusion
Hi, We've built a board based on the mono AEC vocalfusion reference design and want to control parameters like AEC on/off and tuning using i2c from another device in our hardware stack. I am looking for a specification of the i2c commands that I can use to do this. I have already seen that there are...

Re: Intermittent XFLASH behavior
Probable reasons for the error are listted in the following link: http://www.xmos.com/support/knowledgebase/design-tools/why-do-i-get-xrun-cannot-load-image-xcore-0-not-enabled-error Hope this helps. Hi I am having the issue where the xmos device is seen by the xtag and ide but on flashing it repor...

Re: I would like to ask the question if XVF3000 support multiple I2S input?
Hi, can I ask you to clarify what you mean by a "1b port"? I am looking to do something similar, using I2S only config, with xmos as slave, but I am looking to have an additional I2S input AND output for general purpose DSP/Mixing of signals. Page 17 of the vocalfusion speaker hardware man...

Re: How can I access full/partial i2s builds and source?
My apologies, I hadn't fully familiarised myself with the xTime composer interface and was searching for the build configs in the wrong way. For anyone who comes up against the same problem, they're not stored as files, but can be accessed via the 'project>build configurations' menus in xtime compos...

Re: How can I access full/partial i2s builds and source?
Thanks but this seems to refer to a different product, or to ways to modify and rebuilding existing configs. I'm referring to the builds that are literally referenced in both the 'getting started' guide and the software guide for the vocalfusion circular array - so I'd be very surprised if I had to ...

How can I access full/partial i2s builds and source?
Hi, I have the vocalfusion circular array speaker (3100), downloaded the reference binaries and requested and downloaded the vocalfusion software, but I cannot find in any of those files the builds/source for full or partial i2s which are referred to in the getting started documents or the hardware ...
