CCS/TMS570LS3137: tms570ls3137

Part Number: TMS570LS3137
Other Parts Discussed in Thread: HALCOGEN

Tool/software: Code Composer Studio

Hi, 

i am trying to execute a loopback program in the examples of halcogen for the model(tms570ls3137). I don't know how to see the output of the loopback program in ccs. Help me to figure it out.

Is there any changes i need to do in the target configuration? or some other issues that i need to change.

Thanks & regards

RrM

    Hello Raja,

    The loop back test should be storing the results in a RAM location or array of values received and a separate one for values to transmit. You could set up a watch window in CCS to view the content of the RAM location or the arrays or use the memory browser to look at the specific address of the RAM location or array of data.

    As some alternatives, you could setup a more complicated UART interface and output the values to a console but this may be much more trouble than it's worth. A final alternative is to setup a compare in your application to test the received value against the transmitted and toggle a GIO that can be monitored on a scope to show that the data sent == the data received.

    Hi, chuck
    thank you so much it worked,
    can you give me some examples to interface a LCD (with TFT touch(7inch)) with tms570ls3137 using spi communication please.
    thanks and regards

    Hello Raja,

    We don't have such examples available and they would be dependent on the needs of the LCD controller that is in the TFT display. Usually it is a matter of sending address and configuration data to the LCD controller much in the same way you would to an external EEPROM chip. It might be worth while to see if the LCD manufacturer has examples of some SPI interface code. Even if these are for a different chip, you could emulate the flow and messages to the LCD using he Halcogen drivers for Hercules.
