AN099 Wireless Audio over USB

Other Parts Discussed in Thread: CC2511

Hi, I am trying to follow AN099 using a CC1110 as the Tx and CC1111 as the Rx.  I was able to successfully(?) program the CC1110, however I have not been so lucky with the CC1111.  In AN099, it refers to a zip-file that contains 2 projects: CCUSB2 and CC1110_AIC3104_16kHz16bits_96.  I used the latter for programming the CC1110.  I was going to use CCUSB2 to program the CC1111, but all of the project files in that folder appear to be for the CC2511.  Am I missing something?

Thank you.

  • Most of the registers are interchangeable between the 2511 and 1111. Frequency, offsets, and a couple of other registers may have to be changed. RF Studio should help with that.

  • Thanks, ronnym, for your reply.  So just to be clear (I am new to this), would that involve me: 1) applying the appropriate comm settings in SmartRF Studio, then 2) copying those register values to tw_rf.c to match the 1111?

    I will be happy to report my findings on this once I've given it another effort!

  • To fix this problem, I ended up simply changing the chip define in the project options.  First, by updating the target in the general options, next by updating the pre-processor define in the assembler options.  I flashed the CC1111, and when it is plugged in, Windows shows the device labeled as "USB CC1111 MIC".  However, I am now wondering if there are some specific drivers that I might need... does anyone have any thoughts on this?

  • Oygo -

    You are correct - the wrong program version (the CC2511 version)  of source code was attached to AN099. The correct version is attached herein. I'll have the WEB version updated within a few days.

    5582.CCUSB2_CC1111_16kHz.zip.

    Sorry for the mistake!

  • Hi,

    I have the following question: if I want to make USB Hid audio playback by using CC1111 USB audio dongle so what do I need to change in your project 5582.CCUSB2_CC1111_16kHz? I know that I need to change the numbers in the file named usb_audio_descriptor.s51 (but what numbers?), make some changes in other files of usb class_audio, but what exactly?
