硬件iic，EV6卡死问题，急求解决 I2C_CheckEvent问题

Buring

while(!I2C_CheckEvent(I2C1,I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED));单步调试后卡死在这个循环中，下面是这个库函数。硬件为mpu9250和stm32c8t6,网上查到的解决方法都试过解决不了问题，球求各路大神帮忙看看 ErrorStatus I2C_CheckEvent(I2C_TypeDef* I2Cx, uint32_t I2C_EVENT) {   uint32_t lastevent = 0;   uint32_t flag1 = 0, flag2 = 0;   ErrorStatus status = ERROR;   /* Check the parameters */   assert_param(IS_I2C_ALL_PERIPH(I2Cx));   assert_param(IS_I2C_EVENT(I2C_EVENT));   /* Read the I2Cx status register */   flag1 = I2Cx->SR1;   flag2 = I2Cx->SR2;   flag2 = flag2 << 16;   /* Get the last event value from I2C status register */   lastevent = (flag1 | flag2) & FLAG_Mask;   /* Check whether the last event contains the I2C_EVENT */   if ((lastevent & I2C_EVENT) == I2C_EVENT)   {     /* SUCCESS: last event is equal to I2C_EVENT */     status = SUCCESS;   }   else   {     /* ERROR: last event is different from I2C_EVENT */     status = ERROR;   }   /* Return status */   return status; }

是地址不对吗？可是我看地址应该没问题吧

网上能查到的解决方法都试了试

各位大神又碰见类似情况的吗

帮帮孩子吧

日渐秃兀

硬件的 用CubeMX配就试过 库函数和寄存器的没试过 9250你可以看看正点的那个 看看能不能移植个模拟IIC吧！论坛有硬件IIC驱动OLED的 用的CubeMX
