Thanks for you reply, After reading the code, I think the argument 1,0 should be right. But the result is strange. when there isn't a sender , the value returned is always 12. While there is a sender and the distance between sender and receiver is less than 1m, the value returned is between 0~24 (maybe less than 12), no matter what the tx-amplitude of sender is. Does the result make sense?
Thanks a lot. P.S. the result with a sender: 4 24 8 20 24 16 20 20 20 8 8 20 16 20 20 16 4 12 24 0 20 24 8 20 0 8 12 16 0 16 4; the result without a sender: 12 12 12 12 12 12 12 12 12 12 12 12 12 12 2010/6/1 Eric Blossom <e...@comsec.com> > On Mon, May 31, 2010 at 04:42:47PM +0800, jf w wrote: > > I'm using RFX2400 daughterboard on side B, my arguments are slot=2 > > which_adc = 0 ,and I'm calling it from python. > > > > Your question inspire me that my arguments may be wrong.
