CC1310: Why I use GPIO_setConfig() to config CC1310 GPIO ,the GPIO not output my write value?

Hi Tian,

It seems like you are using both PIN.h and GPIO.h drivers, which is leading to conflicts in the GPIO initialization.

thanks for your reply, it seems I use PIN driver defined paramter in GPIO driver API cause this problem.
