working of I2C with CC2530

Other Parts Discussed in Thread: CC2530

Hello all

I am working first time on cc2530. I need to use I2C to interface with cc2530 module. But as CC2530 doesn't have hardware support for i2c , I have to implement it.
Somwhere in forum I found to file hal_i2c.h and hal_i2c.c. Now I want to write my own application for reading data from a sensor through i2c, but I am not able to do that.

I modified the hali2cinit function with the pin and port I am using. Now please tell me where to edit the file to make it work with my application.

Best Regards

Shakti.

Since you have modified the Pin and Port that you use and init I2C, you can try HalI2CSend to send data through I2C.

Thanks Yikai for your quick response

I am doing the same thing, but it is not working.

#define ADDRESS 0x40
int main(void)
{
int8 response;
uint8 st[1]={'s','j'},*buf,,len;
len=strlen(st);

HalI2CInit();

response=HalI2CSend(ADDRESS,st, len);

}

Best Regards

I suggest you using scope to check if I2C clock pin outputs correct signal.

Hello Yikai

Do you mean you don't see signal on data pin? Have you checked it with scope too?
