ADS131A04EVM: starting conversion

ADS131A04EVM: Conversion involving third party SBC(RassberryPi and Arduino)

Part Number: ADS131A04EVM
Other Parts Discussed in Thread: ADS131A04

Hi, I am using third party SBCs such as RassberryPi program in this link and Arduino program in this link to access ADS131A04EVM through SPI.

However, I am not sure on the hardware pin configuration.

Currently the RPi only gets the return with 0x0000s from SPI channel, which indicates that the communication is not set successfully (same as "not connect to any device").

I wonder what is the pin configuration (on JP, M0,M1,M2 ... etc) necessary for RPi-ADS131A04 system to send commands like UNLOCK(0x0655), RESET(0x0011) and WAKEUP (0x0033) through SPI.

Or there is any hardware configuration reference/guide for such system structure.

Thanks for the help. Kuo-Hsuan.

    Hi KuoHsuan Lo,

    There is no specific documentation available to help you get the ADS131A04EVM running with the RPi, but you can review the schematic in the back of the users guide for the ADS131A04 EVM and find the connections for MISO, MOSI, SCLK and CS that would connect to your controller. The pin field in the middle of our board is setup so that you can completely disconnect the TIVA controller and use your own. There are also hardware jumper that you can use to manipulate the mode pins (M0, M1, etc).
