Hi support team,
We are trying to use our ble mcu to drive bhi 360 via spi interface, but failed to get data back. We have the test few mode on cpol and cpoa with 11and 00 mode. The vdd and vddio both given with 1.8v. The resetn is low, and interrupt line is not controled. Picture attatched is the waveform we send to the bhi 360 via SPI. Is there any different between the required one and our? We have proting the code form coines, eulers.c , to a arm m0 based mcu. Could your give some hint for confurging the spi interface?
best,
jack
