C6711DSK+ths1206evm communication

Other Parts Discussed in Thread: THS1206

I want to communicate with a THS1206evm (slau042b.pdf) from a C6711 DSK , and have tried using the example in SLAA210A.

 

My question is: how do you determine the ADC Address which should be entered in the Data Converter Support (DCP) tool, which creates the files used in a program to call the functions such as dc_configure(), anddc_readblock()?

It seem like the DSp does not read anything.

 

I use this configuration:

Interface Settings                                         ADC Settings

 

ADC Address - 0xA0000000                      Channel Set:                   Autoscan 4 SE

Data Shift        - 0                                           Conversion Clock:         6000 kHz

DATA_AV Polarity - High                              Mode                                 Continuous Conversion

Data_AV Type       - Pulse                            Trigger Level                    4

Read/Write Type  - RD/WR                          Test Mode                        Normal Mode

Data Format         - Binary                                  Ref Voltage                       Internal

DSP Interrupt       - Ext Int7

    Hi Alicia,

    The old THS1206EVM referred to in the SLAU042 document used an OR gate to control the /CS1 input to the THS1206.  The inputs to this OR gate are shown on page 25 of the SLAU042 document.  These pins went to XA20 and XA21 on the parallel interface connector.  Unfortunately, I'm not sure which physical pins these connected to on the C6711 processor - Spectrum Digital may be able to help you locate the original schematic for the TMS320C6711DSK.
