Hey Charles,
Thats what it looks like to me. Usblib is only setup to work with a single endpoint IN/OUT. You do however make a great point and maybe I need to re-think my approach since the throughput doesn't change relative to endpoints for bulk.…
Part Number: TM4C123GE6PM Hello,
I have a modified version of the USB bulk transfer example for the TM4C123GXL launchpad up and running. I'm seeing the successful microsoft OS string descriptors coming to the MCU and need to handle this request to load…
Part Number: TM4C123GE6PM Hello,
I'm trying to figure out how to use the usb driverlib "device api layer" and specifically how to pass the config/interface/endpoint descriptors. The device info structure seems to NOT include these, but does…
Part Number: TM4C123GE6PM Hello,
While reading the datasheet about the USB controller in device mode I noticed there is 4k of ram/fifo allotted to the endpoints as well as a single buffering/double buffering mode. I'm attempting to use bulk transfers…
Hi Robert,
You can modify it and see if are able to extend for MS string descriptor. Let us know the result and I'm sure it will benefit others who may need to support this non-mandated USB feature.
Part Number: TM4C123GE6PM Other Parts Discussed in Thread: EK-TM4C123GXL Hello,
I have a hid data pipe device up and and running and I am trying to figure out if it is possible to use the other endpoints in the part to transfer data. I think HID is generally…
Part Number: TM4C123GE6PM Hello,
I am trying to figure out how to approach a USB project with a Tiva MCU. I need to transfer with the MCU as a device using bulk transfers. This way I can utilize the most bus bandwidth available. I'm using USB 2.0 and…
Part Number: TM4C123GE6PM Hello,
I'm trying to better understand how to turn the bulk USB 2.0 TM4C launchpad project into a basic bulk pipe to move data to software using libusb-win32 so it works like the TI custom HID data pipe example application.…
Part Number: TM4C123GE6PM Hi Champ,
I am asking for my customer. Sorry for that, I am not familiar with TM4C this product.
My customer set the GPIO as output, and found out the output voltage is only about 1~1.5V(the normal voltage is 3.3V).
I am asking…
Part Number: TM4C123GE6PM Hello,
I have an input filter that connects to an ADC in the MCU mentioned here. I want to characterize my systems overall noise or SNR. I'm wondering if my approach is correct.
To measure SNR on my system to characterize…
