Connecting two boards

shreyas ravichandra

Hi,

I am working on a project for FSK Modem and i want to perform the Modulation and demodulation separately on two different boards. But i am facing problems in obtaining the synchronized output from the second(demodulator) board. I obtain the modulated FSK signal from board 1 and use it as input to board two to demodulated. Since, both modulation and demodulation processes do not start at the same instance i am not getting the desired result. Can anyone pls help me out with what is to be done?

Thanks for the reply Pubesh. I am working on the TMS320C6713 DSP kit.

Shreyas Ravichandra,

It is used in combination with RTDX test points to allow signal injection and testing of a DSP Algorithm.
The best place to look for DSK troubleshooting and software updates is:

You can get the DSK6713 test code and technical reference guide at spectrum digital.

In addition that, you can find useful information at the wiki page,

Shreyas,

How have you connected the two boards to transfer the modulated FSK signal? Are you doing anything there to synchronize the two boards or the data for that direction?

How do you want to use or access the demodulated data output from the second board?
