选择发送时钟,使能中断。 2).register_irq(27, i2c_interrupt_func):注册中断处理函数,当发生I2C中断的时候就会调用i2c_interrupt_func中断处理函数。 初始化完成后,就可以调用do_master_tx写I2C从机了,这个函数仅仅启动I2C传输,然后等待,直到数据在中断服务程序中传输完毕后再返回。函数代码如下: 代码语言:javascript...
1) You can't allocate the I2C interrupt to your own handler and use the IDF's I2C driver, and 2) you cannot call i2c_master_cmd_begin(...) from an ISR. And possibly 3) I2C will not do anything (interrupt...) while the master isn't actively performing a transaction. I don't...
CC2650 I2C通讯和Interrupt共存 Other Parts Discussed in Thread:CC2650 加速计传感器通过I2C 和CC2650通讯,CC2650开发板一直处于睡眠状态,直到加速计传感器位置发生变化产生一个中断给CC2650,CC2650才被唤醒。请问I2C和中断共存该如何实现?

Hello, I am working on MPC5606s Controller. I am trying to implement a I2C RX/TX driver using interrupt vectors. I have an I2C library that works
