Difference between chanend c_test and chanend? c_test

Hi,

sorry for this question, but I haven't seen it documented anywhere. In arguments of tasks in XC I see a lot of chanend c_test, but also chanend? c_test or chanend ?c_test. What is the difference between them? Are the ones with a question-mark passing pointer or something like that?

Thank you.

Re: Sending custom command over USB (HID) to USB Audio SW

Thats not really what we need. I know there is CDC or HID libraries, they work fine on their own. My point is how to implement this to the audio software we already have running :( Any ideas? Could be HID or CDC or anything else.

Re: Sending custom command over USB (HID) to USB Audio SW

Or is there a possibility of CDC USB that could be enabled only if a button is held on powerup? Not the greatest idea, but I'm trying to find a solution...

Sending custom command over USB (HID) to USB Audio SW

Hello guys, its me again. Just wondering how hard is sending a command (we just need one command to initiate specific sequence in our user code) from windows machine (winusb or libusb) into xmos running your USB Audio SW? We don't really want to create composite device or anything like that. We just...

Re: Two USB audio stacks running on two XLinked XMOSes

Well, we didn't get to that stage yet. We have two XMOSes on the board with their separate JTAG headers working. Now we found out that we can have one flash memory and boot both MCUs, which simplifies our design a lot because we need to have working DFU in both MCUs.

Two USB audio stacks running on two XLinked XMOSes

Hello guys, just dealing with another design and this time we are implementing XU216 and XUF208 in one design, we will connect them thru XLink and XTAG so we can boot all three tiles from one flash from the XUF208. Do I understand correctly that now I will have to have one project with three tiles i...

DFU not working on XUF216-512 platform

Hello guys, I'm struggling with DFU on our XMOS XUF216-512 platform running USB audio. First I burn the factory image with 0x104000 boot partition size as: xflash --factory test.xe --boot-partition-size 0x104000 Then I get whats in readout.bin which was read from the actual memory. It looks like the...

Re: Setting up an Clock block from MCLK input

Same thing, doesn't really matter where I init/start the clock block :( I had to deal with it for this design with external counter...but would be nice to have it working for future designs... Maybe next time I just put another MCK 1b port to tile 1 and run it there.
