Setting up ADC with TI-RTOS

Michael He
Expert 2170 points

I'm working on the F28M35x, and trying to read from the ADC while running TI-RTOS. I'm already able to get the ADC running without TI-RTOS, but I am at a loss for how to mesh the two together. The Non-TI-RTOS example uses a lot of headers and .c files that conflict with TI-RTOS, and if I try to merge the linker command files, it is an utter mess. I've tried looking through the TI-RTOS User Guide, examples, and the configuration files, but there is absolutely nothing there about the ADC.


Thanks for any help.

    That looks like exactly what I'm looking for. Thanks!

    Working through that example, I do run into one issue. The C28 portion of the TI-RTOS Demo example seems completely different from the SYS/BIOS that your example talks about. I am trying to port the Demo code over into the SYS/BIOS Adc example, to incorporate the interprocessor part, except that the Demo code has modules that do not appear in the SYS/BIOS config, such as the MessageQ and IPC.

    For example, adding this line directly copied from the Demo example to the SYS/BIOS .cfg file gives an error:

    var IpcMgr = xdc.useModule('ti.sdo.ipc.family.f28m35x.IpcMgr');
    IpcMgr.readAddr  = 0x3FC00;
    IpcMgr.writeAddr = 0x3F800;

    Gives the error:

    Description    Resource    Path    Location    Type
    xdc.PACKAGE_NOT_FOUND: can't locate the package 'ti.sdo.ipc.family.f28m35x' along the path: 'C:/ti/bios_6_35_04_50/packages;C:/ti/ccsv5/ccs_base;C:/Users/mhu/ti/Workspace/task28_F28M35H52C1_TMS320C28XX/.config/;C:\ti\xdctools_3_25_03_72\packages;'. Ensure that the package path is set correctly.    task.cfg    /task28_F28M35H52C1_TMS320C28XX    Configuration Validation    XDCTools Configuration Marker

    Have these been deprecated? Is there an alternative way to send messages?
