Other Parts Discussed in Thread: ADS131E04

Hi Brain,

Thanks for reply.
Can you help me to find about interfacing this ADC with TI AM335x series which is running on Linux? From this I can get some help.

Thanks,
Bhavesh

Hey Sitara engineers,

Bhavesh would like to know if we have any Linux SPI drivers for the Sitara that would help him program for one of our precision data converters. Any help would be appreciated!

Regards,
Brian Pisani

The Sitara Processor Linux SDK has a generic McSPI driver: processors.wiki.ti.com/.../Linux_Core_SPI_User's_Guide This will support a number of SPI Flash memories, but there is no built-in support for data converters.

Hi Biser,

Thanks for guiding. I have done implementation for Micron Flash on SPI. I will think something for Data Converters. I will try without drivers with SPI functions and will check results.

Brian,
Can you point me guide which are having steps listed to set Sampling Rate and Data Accuracy for each channel. From that I will check whether driver is required or no.

Thanks,
Bhavesh

Bhavesh,

Figure 31 in the ADS131E04 datasheet shows a flow chart with the steps for initial configuration for that device.
