Forum Post: CC2511 development examples

jremi

I currently have a design that uses the CC2500 on both transmitting and receiving ends. I just got a CC2511 development kit with the intention of using the USB dongle to take the place of my receiver so I can send data directly to the PC. Sounds easy enough, right? Well... I have some of the examples...

I have modified the usb dongle example firmware for CC2511 recently by removing all Radio related part and creating my own Fifos for application level buffers for USB handlers. I then used SimpliciTi stack examples for CC2500 to make CC2511 a USB-RF Gateway. Radio part in usbdongle firmware is a bit...

Forum Post: Re: dm6467 USB host

Juan Gonzales

The features and limitations of the USB driver are detailed in the PSP release notes (e.g. ReleaseNotes_DM646x_Linux_PSP.pdf) which are included as part of the DVSDK. I believe the limitation in the number of devices that can be supported are based on the types of devices; certain devices use an entire...

are all 10 devices interrupt-type devices? I think you can implement a software arbiter to manage the end-points; I do not know how difficult this would be though.

esy

Hi Keith. You've looked at the code in the USB examples ( SWRC088 ), right? I think the best way to make an application for two CC1111 dongles would be to look at the serial port example and use the USB dongle example code on one dongle (CC1111), and then for the other dongle start with the same...

This is indeed the better place for this type of question :) The OMAP35x SDK does provide support for USB devices, and it has been tested, though there are several limitations still present with the USB drivers as discussed in section 2.6 of the PSP release notes . You do have to have a MiniA ended...

Hi, thanks for the reply. I already had considered all the details posted so far. I also checked the cable if the ID pin was actually connected to ground, and it was as it should be. So the cable is not broken or something like that. Im also using a powered HUB. When I do a "cat /proc/driver/musb_hdrc...

Hi everyone, It turned out that my OMAP35x board was broken. I tried another different board one, and USB devices are detected just fine. But, it does not work either. Either with the original SDK 1.0.0 default kernel or custom kernel with different USB driver settings (experimental code for better transaction...

Hi, thanks for replying, but I have been using ALSA for several years (as user, driver and application developer), and I have never had any problems with multichannel. I also have other ARM based systems working just fine with the very same audio cards in multichannel mode. I will try using another USB...

Good to know that you are familiar with the ALSA infrastructure quite a bit. We had an issue with the usbaudio.c code in "sound/usb" directory were the USB flags were not correctly updated. This lead to random oops after recording stopped. We corrected the issue by correctly updating the...

Sorry, I was focusing too much on the audio portion of the issue and blocked out the USB. Based on the log you sent earlier, it appears the USB device is not being recognized; therefore this is not an ALSA/audio issue but rather a USB device interface issue. I agree ALSA supports multiple channels...

Lori Heustess

The D+ and D- pins are 3.3V tolerant just like every other pin, and the USB data signals are 0 to 3.3V signals so no level translation is required. VBus is in fact 5V and cannot be directly fed into a GPIO without damage. However as you can put a resistance in series with VBus and use the internal...
