  • Forum Post: C5505 I2S driving capability

    a shen
    Hi, We are thinking to interface ADC and DAC using C5505 I2S. Since we have multiple ADC/DACs on board, One ADC and DAC might need to be connected to the same I2S port. Does anyone know if the C5505 I2S port (in master mode) have enough driving capability for 2 slave devices? In our project, the ADC...

  • Forum Post: Hacking the Data Converter Plugin to support other serial ADCs, and importing code to CCSv4.1.. and of course... nothing works. :(

    FastFourier
    So I'm working on a new design here at work, and the hardware engineer decided on a C5510 and a Linear Tech LTC1407 serial ADC. Since I've never used a C55xx before, and don't know how its DMA engine compares to the EDMA3 from C6000s, I thought I'd try to use the Data Converter Plugin...

    Fangyi, The closest example software I know for what you are trying to do is \CSL_SAR_DmaExample which is delivered with CSL v2.10. You can obtain the LOWPOWER CSL from this site: http://focus.ti.com/docs/toolsw/folders/print/sprc133.html . Regards.

  • Forum Post: How to configure some pins as general purpose input or output in C5510a?

    Shanjie Chen
    Hi, I want to use C5510a DSK to read external data from AD7813. The AD7813 has 9 output pins( 8 data output pins and 1 busy signal pin) and 3 control signal pins(CS RD CONVST), but the C5510a has only 8 GPIO(general purpose IO) pins, I still need another 4 IO pins . In the datasheet of C5510a,...

    Shanjie Chen
    I want to use C5510 DSK to read data from ADC7813, whcih has 9 output pin(8 data pins and 1 busy signal pin) and 3 control pins. Since the HPI Expansion Connector has only 3 GPIO pins, can I use the data bus D[31:0] in "Memory Expansion Connector", or HD[15:0] in HPI Expansion Connector...

    CHAIX Julien
    Hi I work on the TMS320VC5505 and I want to use the SAR to measure the battery's voltage. I have done it without use CSL. I use the channel1. And I don't understand the value in SARDATA. For example: if I supply my board with 2.6V, my voltage is divided by two before enter in GPAI0 with a divider...

    Hi I have seen on the documentation about the sar (sprfup1) at the page9 that the voltage on GPAIN0 must be lower than VDD_ANA - VT ! I have never found information about VT ! What is the VT's voltage ? Thanks for your help Julien

    Sam Delacruz
    Hi Folks, For a school project, the ezDSP USB Kit TMS320C5535 was chosen as the development platform. Our current quandary has to do with configuring the DSP to work with an external ADC (ADS8319) which uses a serial SPI interface. The internal ADC of the C5535 does not meet our performance needs...

    I'm looking at an application for the TMS320C5515 where I need to ingest at least 4 channels of audio data. I'm hoping I can use a 4 or more channel codec such as the pcm3168 or AK5388. From what I can tell, the I2S controller in the C5515 only directly supports stereo audio. Is there a way to...

    Hi, I know that the C5515 eZdsp board has expansion connectors for external signal I/O. I'd like to know what kind of setup would be needed to take the output from, say, the ADS1299 eval module, and send it to the C5515 eZdsp for processing. I don't currently possess either board, so the solution...
