Thread Summary

                The user transplanted BIA code to a new MCU platform and can read the AD5940 ID and trigger interrupts, but cannot read data. The final answer suggests checking the AD5940_CLKCfg, BiaODR, and WUPT sequence timing settings for consistency with the MCU's SystemClock_Cfg and SPI clock. The user also inquired about the need for interrupts in AD5940 and how to verify their proper functioning.

I transplanted the code of BIA to the new MCU platform, SPI has been tuned, I can read the ID of ad5940, the program can run, and it will trigger an interrupt, but I can't read the data. What's the reason? Who can tell me? Or tell me how to find out what the problem is?


i don't konw where is question,please help me solve the probleme!
