RTOS/AFE5816: How to let the AFE work without the use of TSW1400? Could it be done by writing SPI to AFE? How could the SPI be written into the AFE?

Part Number: AFE5816

Tool/software: TI-RTOS

To someone who may concern,

Hi, I am a PhD candidate in Nanyang Technological University, Singapore. Now we are trying to construct a portable medical system concluding sensors, AFE, wireless module and FPGA, applying to ultrasound healthcare. We use AFE5816 as the analog front end, however, we don't want to use the TSW1400 because it needs to connect to computer and use the GUI. which is not suitable for portable devices. We try to let the AFE5816 work without TSW1400 by applying the SPI signals(SCLK, SEN,SDATA) to the AFE5816 through Arduino. We have removed the R22 near U9 at the bottom of the board as the manual indicates, however, the SPI still could not be written into the AFE5816. Could I ask how to write SPI to AFE5816 or do you have any other suggestions to let the AFE5816 work without the use of TSW1400? Thank you very much!
