  • TM4C123GE6PM: USB Device - Bulk - Double buffering packet help

    Resolved
    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…

  • RE: TM4C123GE6PM: Can USB driverlib handle 0xEE Microsoft OS descriptors?

    Resolved
    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.

  • TM4C123GE6PM: USB Device: Why TI's USB device descriptor only single char?

    TI Thinks Resolved
    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.…

  • TM4C123GE6PM: GPIO output voltage abnormal

    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…

  • TM4C123GE6PM: How to measure SNR with ADC

    TI Thinks Resolved
    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…

  • RE: TM4C123GE6PM: ADC_Conversion

    Hi, It looks like the customer never takes my advice on how to debug his code. Here is a complete TivaWare code that will sample two channels. I also capture the entire register settings. In this example, I tie AIN0 to 3.3V and AIN1 to ground when running…
