CC2540 I2C

CC2540里I2C能直接用RemoTI-CC253xDK-1.3.1项目里的hal_i2c.c文件吗，还是这个只是参考，需要修改后，才可以用

Yue TANG：

BLE 1.3里有对I2C的驱动。 sensorTag例子就是I2C驱动传感器。另外CC2540不带硬件I2C, CC2541才有I2C.

我意思用软件模拟I2C的话是不是RemoTI-CC253xDK-1.3.1项目里的hal_i2c.c文件可用，CC2541和CC2540区别是 you’re concerned with active power consumption, use CC2541, as it will save you 30% in TX and around 10% in RX.

If you need +4 dBm output power, you should choose the CC2540.
If you need a USB interface, you should choose the CC2540.
If you need I2C, you should choose the CC2541.
If you want to communicate using a proprietary protocol, you should choose the CC2541.
If none of the above apply, it doesn’t matter which one you choose. 
If cost is important, CC2541 is priced slightly lower than CC2540.这些吧其他通用的吧

没试过，不过CC254X与CC2531 Pin to Pin.你可以试一试。 我的建议是如果你是使用CC2541还是使用B LE STACK提供的hal_i2c.c. 有例子
