Part Number: CC2531

Hi Guys,

I´m working with CC2531 ZNP-Debug file to building a Zigbee network and receive and send Zigbee message using a Raspberry Pi3 as Zigbee exchange processor (Zigbee gateway), with raspibian Linux inside. Firstly I need to parser messages (HID USB) received and sent form CC2531. I using Texas Zstack

I have problem to get a input events on raspbian Linux, To fix it I using PyUSB to fix it.

I using a LadyAda video to configure a Python Script. She uses another USB device.

I need to find in a CC2531 CDC firmware informations, equivalent that LadyAda uses from another USB vendor CP2105. In a video attached she call at Read_Latch those parameters:

bmRequestType

bRequest

wValue

wIndex

wLength

Somebody can help to find an equivalents parameters used in a TI CC2531 CDC firmware?

Hi Ryan, thanks a lot for your assistance. I really have appreciate a firmware information that you shared w/ me.

But I can´t find, in USB firmware libary help, the parameters bmRequestType, bmRequest, wValue and wIndex fields of the standard control transfer structure.

Do you can help me to find it?

Best Regards,

Alex

I have no technical expertise with USB protocol but you appear to be inquiring about the USB_SETUP_HEADER struct defined in usb_framework_structs.h, which is the data type usbSetupHeader is set to in usb_framework.h. You can also check usb_cdc.h for USB CDC definitions.

Hi Ryan,
I found the parameters but i didn´t identify on files all those values for Request type, bRequest, wVal and wIndex.

Do you know an specific document, like Silicon Labs have for CP210x, form TI that I can see it ?

I'm not entirely sure, as mentioned before I am out of my element with this request. Drivers are distributed by the SmartRF Studio and can be inspected from the installation path in case that can provide any further hints. www.ti.com/.../swru222.pdf
