Hello, Does anyone have experience in using RTDX communication with 28xx DSPs? I've been struggling for a long time to establish communication between my F2808 DSP, which I use for a high-speed motor control, and a PC. I have succeeded to send and receive data to and from DSP, using parts of a code that I found in 'rtdxtutorial' in Matlab, but I cannot make both RTDX and my interrupts to...

Hi, I'm using the SOCA signal from ePWM to fire the ADC SEQ1. The problem is the ePWM that isn't counting, they stay with value equal to zero every time. I had set the FREE bit, so they must run ever with the system debug stopped, right? If I manually set the EPwm1Regs.ETFRC.bit.SOCA, the ADC take a sample. Someone see this problem and know how to workaround? EALLOW; EPwm1Reg...

Greetings, You are experiencing the endian problem between the two processors. Do not send a structure. Define fields and "copy: each field into the message and out of the message. Another problem may be due to the way your compiler may actually allocate structure s_x. It may not pack them as expected.
