summary before lunch

Here is where I am at:

1. I can add rtdx blocks to my models if I add:

/* MODULE RTDX (taken from the RTDX demo) */
_RTDX_interrupt_mask = ~0x0000;


to my cmd file.


2. Now that I do not have any to memory or from memory blocks, i can use the standard cmd file with the memory map set to internal. However as this cmd file does not reference the _RTDX_interrupt_mask, I cannot use rtdx blocks


3. When I use RTDX blocks with the open loop program, it runs okay as regardless of the sample time as long as the rtdx blocks are disabled.


4. When I use RTDX blocks in the open loop program, the motor's operation is effected when i enable the rtdx if the rtdx sample time is above about 0.0002 (5k).

5. When I use RTDX blocks in the closed loop program, the motor's operation is effected if I have a diabled rtdx block with a sampling rate that is too fast

6. in the closed loop program the motors operation is further effected if I try to enable the rtdx block

7. This seems unresonable that the operation of the DSP should be effected. I cannot look at the cpu loading unless I figure out how to set the program up as a DSP/BIOS program
