<div>Dear Experts,</div><div><br></div><div>I am using SBC 9260 for development of a data acquisition platform. I am<br></div>
using the SPI for data acquisition through 14 bit ADC slave. Currently<br>
my board has debian 5.0 kernel version 2.6.30. I am using the spidriver<br>
(spidev )for using the SPI on the board in master mode . Everything is<br>
working fine and I am able to send and receive data . The only problem<br>
is between the activation and deactivation of chip select.It takes<br>
around 70microseconds for chipselect deactivation and then activation .<br>
Since speed of my 4 channel ADC is 1MSPS so i need to bring down delay<br>
as minimum as possible. I checked out the value of the registers<br>
DLYBCS , DLYBCT , DLYBS and all are indicating the values 0.<br>
<br>
Therefore I don;t have any idea from where the delay is being<br>
introduced. Is it a problem of OS or there is nythng else involved .<br>
Kindly guide me through this . I need urgent help .... any information<br>
abt delay is welcome.<br>
<br>
regards<br>
