McBSP and Parallel Port operating simultaneously

Hi Brady,

Thanks for the post.

I have code to operate a DAC through the McBSP serial port as well as separate code to operate the ths1206EVM.

Could you able to operate both DAC & ADC independently?

However, when I try to operate my TLV5616 while the ADC EVM is plugged in, there is no output. I can look at all the signals going to the DAC via a scope and all the data seems to be sent properly. Any suggestions? Is it possible to operate the Mcbsp port while the ADC EVM is connected?

1. I understood that you were using the C6713. Is it a DSK6713 or custom board? Please confirm.

2. The possible combinations of C6713 peripheral is documented in the C6713 datasheet(SPRS186), Section DEVICE CONFIGURATIONS(Page No 32).

3. Please ensure to use correct McBSP port(0 or 1).

4. Could you please elaborate, how the ADC EVM is interfaced with C6713?

Please found the below thread which may help you.

Hi Rajasekaran K,

Sorry I did not provide more information. First of all, I am using the TMS320C6713 Starter Kit: http://www.ti.com/tool/tmdsdsk6713. I have a 5-6k Interface board. I also have the THS1206EVM connected to the interface board. I am using McBSP0 port for the TLV5616. I am wirerapping the connections from the port as well as reference voltages and grounds to the DAC. I am able to operate the TLV5616 independantly from the ADC, however, when I connect the ADCEVM to the 5-6k interface and attempt to run my DAC code, there is no output. When I remove the ADCEVM, the output remains functional again. Like I said, I probe the different signals and voltages to the TLV5616 such as DATA, SCLK, CS, FRAME SYNC, etc. All of the signals look the same whether or not the ADC is plugged in. If you need some pictures of my setup or configuration code please let me know. 

Best Regards,

Brady
