I have some problems about using AD7768. I use an ARM device to configure AD7768(SPI0 port) and receive DOUT data of AD7668(SPI1 port).I can use SPI0 PORT to configure AD7768 ,but I can’t receive DOUT data of AD7668 through SPI1 port.
For my ARM device .I set the SPI1 port as slave mode, The relative signals are CS, SCLK , MOSI, MISO. For AD7768, all channels data are out to DOUT0, The relative signals are RDY, DCLK , DOUT0. Connecting SCLK to DCLK , MISO to DOUT0 .but I don’t know how to connect CS of ARM device to AD7768? The slave SPI1 work as blow: if CS is low , the rising edge of clock can trigger the SPI, if number of the rising edge of clock is enough, it will enter in an interrupt.
In figure 1,D0 is DOUT0 of AD7768, D1 is RDY of AD7768, D2 is DCLK of AD7768,
How to use arm device to receive AD7768 DOUT data?
I am checking on this. I will get back to you.
I have same problem.
I need the data gave to him.
Could you mail me the data too? Thanks a lot.
