  RE: How to get sounds from four different analog pins synchronously in TM4C129?

  Hello Mehmet, There is a lot more to capture Audio than just configuring the pins to be analog. TIDM-TM4C129POEAUDIO does audio capture with a single Analog Pin and a single ADC. Using 2 ADC controllers can give you simultaneous capture. But not...

  RE: Device visibility in a LAN network

  Hello Chidambaram, No there is no code like that. Ethernet is rather transparent when compared to USB which has defined classes. The manner in which you handle the Ethernet ports and data help provide the services. As an example in the TIDM-TM4C129POEAUDIO...

  RE: TM4C129 Ethernet Guide - Other than example code

  Amit, This thread implies that you have accomplished a distributable and practical UDP example using audio on the TIDM-TM4C129POEAUDIO Audio Communication With Power Over Ethernet (PoE) Reference Design Board. The web site, that your link takes one to...

  RE: TM4C129x sampling ADC at 4MHz

  Hello Shai, Yes, the DMA can be configured to transfer the data. However let me clarify a few points here 1. The ADC FIFO is for each sequencer and the maximum size of the FIFO is 8 for Sample Sequencer 0 2. The FIFO's cannot be combined. ...

  RE: Transfer more than 1024 values using DMA

  Hello Sergio Yes. You can use Ping Pong mechanism where there are 2 1025 element buffers. When Ping buffer are being updated by the DMA, the Pong buffer can be processed by the CPU and vice-versa. A similar software example exists (though not of...

  RE: Multiple channel ADC using DMA error

  Hello Josue When the CPU is processing USB information, it is storing and retrieving volatile parameters and flags in the SRAM. This is the same SRAM where the DMA is also transferring the data. Upto 43KHz trigger rate there are no errors. But above...

  RE: Tivaware Grlib Image Update for ImageButton

  Hello Nagaendra I think the issue is in the manner in which you are parsing the buttons from an array to the Button Structure. I have a similar use scenario with TIDM-TM4C129POEAUDIO but I do not use a structure and I never ran into such an issue.

  RE: TM4C1294NCPDT: adc sample rate set and i2c data

  Hello Prateek Yes, that is correct. Also when debugging such an issue make sure you have 2 things in place i.e. Stimulus and control 1. The input signal is not defined here as a static value or changing value. Always have a static value so that...

  RE: connect TM4C129 with CC3200 Audio BoosterPack

  Hello Khoa No, it is not possible to connect the CC3200 Audio Booster Pack as it requires I2S connection which is not supported. We have a TI design for audio via ADC and Timer www.ti.com/.../TIDM-TM4C129POEAUDIO It is however possible to use...
