Hi TI,

I am planning to use I2C in CC2530. I understand TI CC2530 dont have the I2c module hardware support.It only support TI CC2533.

So to use I2C in CC2530 ,

GPIO p1.3 and P1.4 pin for I2c master. P1.3 use as a clock (use timer 3 to generate pwm clock for 400khz) and P1.4 for SDA.

Kindly advice .whether i can use the above way to communicate with I2C Slave.if there is anyother way please advice.

Thanks and Regards

Lakshman.

I just test on the original hal_i2c.c which use P1.6 as SCL and can see I2C clock on it.

Thanks for the reply sir
What should be the minimum delay for the slave to capture the rising or falling edge,here in my code I have given 200us,is it OK ,or I have to make it less.

Thanks

It depends on the spec of your I2C device.
