Hi, In regards to a TMS320C6701 EVM/THS1209 daughterboard setup C6701 EVM: http://focus.ti.com/docs/prod/folders/print/tms320c6701.html THS1209 EVM: http://focus.ti.com/docs/prod/folders/print/ths1209.html (acts as a ADC) Setup: DSP linked to PCI slot in host PC. Daughter board connected through EMIF (daughterboard Interface) to host DSP BNC connectors off the daughterboard include the following: 1. EXT CLK is a function generator issuing a square waveform at 7.2MHz (5Vpp, 2.5Vdc). 2. There is a T-connector at BINP which links to AINP (which should be inactive according to SLAU065) and a function generator supplying a 1.8Vpp, 0Vdc, sine wave at 250 KHz. ...the reason why I put the AINP and BINP together i know not why, some Tech Support guy at TI told me to do that. If someone knows why you do this/what it's supposed to do, please do share. Problem: I can't seem to find where these analogue values that have been converted to digital are in memory. As well, I can't seem to locate where in the sample code the memory location was assigned for the sampled values are. What I've tried: according to http://focus.ti.com/lit/ug/spru197d/spru197d.pdf section 3.1 Memory maps. (map1), I've looked at the memory activity in each of the IPRAM, IDRAM, CE0, CE1, CE2 and CE3. and did not find anywhere where this data could be. I've looked at each of these sections in detail over an elapsed time. Thanks for any help you may be able to provide. Regards, eric |
