  • Forum Post: C674x, BIOS SPI driver (and ADS1158)

    Admar Schoonen
    Hi I'm using the C6742 in a design with the ADS1158 connected via SPI. (Well, that's the plan. For now the ADS1158 is connected to SPI from the C6748 EVM until HW design is finished.) I use DSP/BIOS 5.41. I guess I'll have to write an SPI driver for the ADS1158, but I'm a bit at...

  • Forum Post: Re: TMS320C6748 SPI slave boot question

    David Leung
    My implementation currently has a time delay of about 7 milliseconds between the end of SWS and the beginning of POS. Does the bootup code in the Internal ROM allow a time delay of this duration between SWS and POS? Thanks David

    David Leung
    Hi All, After more investigation and testing, we have found the followings about the SPI slave boot mode: (1) We are using the correct clock edges for the SPI master to transmit and receive data, i.e. Falling edge for transmit, rising edge for receive. (2) The SPI master has to insert a short...

  • Forum Post: SPI DMA timing

    Admar Schoonen
    Hi I'm using the Logic EVM with C6748 SOM and I'm investigating spi transfer. So far, I have spi working in dma mode. However, like a few others on this forum, I've noticed that there is quite a big delay between chip select and start of spi clock if CSHOLD is set. This delay is not present...

    Steve, thank you for the insight, So- I completely uninstalled all TI products and associated drivers, SDKs...etc. Then I reinstalled everything into the "C:\program files\Texas Instruments" directory to keep it all in one place. I installed the following : -CCS 4.2 -NSP 1.0.0.2 ...

    barry mohan
    Hi Karl Thanks for the speedy reply - typically in previous applications most of my allocations have been static through the *.tcf file and usually I've used SWI's etc. This application is indeed dynamically creating tasks with TSK_create() etc. Have now tested the placement of the element's...

    Hi E2Er's We are developng DSP code on OMAPL138 experimenter board (CCS 4.2, windows 7 & BIOS 5_41_10_36) - also seen on We have IRAM configured in *.tcf as follows base = 0x11800000 len = 0x38000 create heap in this memory = TRUE heap size = 28000 enter a user defined...

  • Forum Post: SPI EDMA performance

    Admar Schoonen
    Hi I have some troubles getting a good SPI performance with the C6748 SOM on the Logic EVM. I've configured the DSP as SPI master, 7 Mbit/s (which turns out to be 7.35) using DMA. When my application calles GIO_write(), all data bytes are clocked out at 7.35 Mbit/s and there is no gap between...

  • Forum Post: UART BIOS not working, C6748 platform

    George Paravas
    Hi, I am trying to get the UART to work (UART bios) but I had no luck so far. I have read the C6748_BIOSPSP_User_Guide, and I have selected the UART example (interrupt or edma behaves the same). The project builds, and it gets downloaded to the evm board (with a C6748 on board), my gel file...

  • Forum Post: Simultaneous uart transmit and receive in DSP/BIOS

    Admar Schoonen
    Hi, I have an application that should receive control commands over UART. One of these commands is a 'start' command, and upon receiving that, the application will regurlarly transmit large amounts of data over the same UART. I have solved this by creating separate input and output handles...
