TMS320VC55055 DSP Medical Evaluation kit (MDK)

Friends,

I would like to buy the TMS320VC55055 Medical Evaluation kit (EVM) to do basic reasearch. The kit has to be attached to VC5505 EVM to which the data can be displayed on small display or sent to PC. Within the board is rs232 port where it can be connected to PC.

I would like to connect the output of this port to the PC then try to read the data (the data is ECG signals being collected from ECG board via VC5505 EVM) into a Matlab software where I can do further analysis. Matlab allows me to create serial port object (e.g. Out = serial ('COM1');) but I am still not sure whether I can read data from rs232 port or not.

 

My question please, can I get the data out of the rs-232 and fetch it into Matlab.Will Matlab recognise the ECG points?

Note: the link below is about the evaluation kit

Your feedback is highly appreciated

    Hi Faisal,

    It appears that you are looking for receiving full ECG data through the RS232 port. Unfortunately, the ECG MDK was not designed to send full ECG data to PC. The existing ECG MDK program does NOT send actual ECG data to PC via UART port. Instead, it sends x-y coodiates to PC in order to display ECG waveforms on screen.

    You can get full source code of the ECG MDK (see the link below), so you may want to try to modify the source code to get full ECG data via UART. In term of system bandwidth, it will take more CPU bandwidth to send full ECG data to PC, so you may need to reduce the data captuer or data processing bandwidth (I am just guessing here). We have not tried to send full ECG data to PC, so we can't help you on this further. 

    Please try the link before to get full source code of the ECG MDK from the link below. It is free. (Under C5515 EVM, there are two versions of ECG software)

    FYI, The code from the link above will run on the C5515 EVM not the VC5505 EVM.

    Good luck and Best Regards,
