Subject: EDM display problem

Hi all,

My EDM does not show me the data transferred but it used to work fine.

I wrote some codes to get a waveform from an oscilloscope, by using waveform record. And I store the raw data into an array, say arraybuffer, and use pwf->bptr=arraybuffer to assign it to the record. The weird thing is, I can use printf to print the data on the console but the EDM could get nothing than zero, and dbpr also shows that the record has a VAL of 0x0000000.

Anyway, could anybody tell me that what may cause it? Thanks.

Best Regards
Chen
