Other Parts Discussed in Thread: CC2430, Z-STACK, CC2530, REMOTI

Hi,

I would like to use I2c on CC2430. The SPI protocor and the UART are fully supported, but how can i get I2C support as well?

thanks,

Nir

Hi,

There are no example code of a bit-banged I2C interface on the CC2430 available from TI, that i know of. Best bet is to search the web for some general and open source code for a 8051 implementation of this.

Rgds,

There is the Z-Stack that can be downloaded which runs on the CC2430. In this software, there is a Hardware Abstraction Layer (HAL) that has implementation of I2C. I presume you want I2C master capability.

The Z-Stack can be found at http://focus.ti.com/docs/toolsw/folders/print/z-stack.html

Unfortunately we don't have a HAL API that supports I2C. So you will just have to bit-bang this since the CC2430 doesn't have an I2C peripheral controller.

Hi Baba Sanfur,

Just google CC2430 & I2C, and you can find the S-Mote from TinyOs supporting the CC2430 with an I2C driver.

One more thing....

This is the best place to go for Open Source CC2430 ideas for firmware and hardware.

Brandon,

Can you be more specific as to the file and the loction which contains the HAL implementation of the I2C?

Thank you for any assistance,

Joel

There is some example code buried deep in the directory structure to use as a guide.

Hi,

I want to use I2C (Bit bang) for one sensor (SHT11) interface to Cc2430 .. I tried to get I2C.c file in the Zstack but could not find it .. can you provide the link /doc to get the I2C.c for cc2430..

regards chethan

Check the RemoTI stack for CC2530. It includes a hal_i2c.c driver that can be ported to CC2430.
