Re: Questions on ethernet (XE devices) and handing data reads

Hello, I have a problem modifying the contents of the 'else' at line 215 of rgmii_ethernet_mac.xc. Removing content of this declaration generates the following error: Error: Undefined reference to '_Srgmii_buffer_manager_0' The code is simply that: else{assert(0);} No problem with modifying other bi...

Programming tutor

Hi, I'm looking for a programming tutor, experienced in XMOS architecture and .xc language. I'm an electronics design engineer with a bit of experience of programming STM32 microcontrollers in C to do simple tasks and a bit of I2C. I have got xCore-200 Multichannel audio platform and I'm looking for...

Re: Combining USB Audio with AVB networking on Multichannel Audio Platform with XEF216-512-TQ128

Just found this thread: http://www.xcore.com/viewtopic.php?f=26&t=4731&p=24242&hilit=rgmii+cores#p24242 Looks like if I run XUD as a high priority then I will be able to have 8 cores on tile 0. Also USB requires 2 cores, not 3. Hence, if I just add two USB cores into existing Gigabit AVB...

Combining USB Audio with AVB networking on Multichannel Audio Platform with XEF216-512-TQ128

Hello, I have got the xCORE-200 Multichannel Audio Platform with XEF216-512-TQ128 and I'm considering to design an application that will combine both AVB networking and USB audio functions on the same device. The point is to stream USB audio over the network, so two PCs can be connected to the same ...

XHRA-2HPA-TQ64

Hello, I have a few questions regarding new chip XHRA-2HPA-TQ64 http://www.xmos.com/products/silicon/xcore-audio/hires From datasheet, it looks like the device comes already programmed and does not even require a flash memory to operate. Those a great news, but I would like to clarify a few things: ...

volume controller

Hi I am currently researching into options to connect an analogue volume controller to one of the XMOS XU devices. The controller in mind is this one http://www.njr.com/semicon/PDF/NJW1194_E.pdf This device specifies 3-wire serial control (Data, Clock, Latch). I wonder if I could use any of existing...

Re: TimeComposer does not build applications

Hi srinie, It is a custom designed (by me) board based on XMOS usb audio reference board, but with different AD-DA chips and PSU. I had some struggle to get SPI memory to work (4mb flash wirebond). Essentially it seems to work now (after I have removed logic buffer IC). At the moment, I am trying to...
