ADS1293EVM SPI probe initialisation

Other Parts Discussed in Thread: ADS1293EVM, ADS1293

I am planning to use ADS1293EVM and stream its output via a Bluetooth device for a demo project. I see that ADS1293EVM has an SPI jumper to probe the SPI pins of the chip. Is it possible to initialize the ADS1293 chip through this SPI probe interface?? I want to collect the output from ADS1293EVM and directly connect it to bluetooth board, instead of reading the EVM output to PC via the USB port. Any help is appreciated.

I am moving your post to the correct forum.

John,

I suggest you remove resistors R25, R26 and R28. This will disconnect MSP430 from the SPI bus so there is no multiple masters accessing the bus. Then you can connect your external controller to control/read data from ADS1293 and send it over Bluetooth.

thanks,

vishy
