Hello I am having a lot of trouble trying to simply read volatge data from an ADC evaluation board connected to a BeagleBoard Rev C4 through the SPI connection.
I am using this board http://www.ti.com/lit/ug/sbau184/sbau184.pdf
and using the ADS1118 (http://www.ti.com/lit/ds/symlink/ads1118.pdf) sheet to get the proper bytes I need to send to get the ADC working.
Plus I am going off of this code: http://www.kernel.org/doc/Documentation/spi/spidev_test.c
Well I am very new to SPI coding and I have no idea what to do really. If anybody can help me or show me a sample code I would truly appreciate it.
Thank you,
