IIC and SSPCON2

[allenkkwong]

Hi Benj,

I am using the PIC16F723 in a project. I use the hardware IIC. When I compiled the FC, it generates a lot of SSPCON2 error. I searched the forum and found that it happens in FC V5. I am currently using FC V6. I have attached the error message in this post. I changed to use software IIC and it seems fine.

Can you tell me if there is anyway to fix this?

Thanks
Allen

Hello Allen,

Aha the problem is also in v7 and I think I have found the cause.

This is taken from the datasheet.

The SSP module, in I2C mode, implements all slave functions, except general call support.

So the chip can only support hardware I2C Slave functionality. For Master functionality you will need to use the software channel. I've added a warning to the I2C code in v7 that says in this case that the master mode may not be available on the device.

Hi Benj,

Will there be a fix? I am using v6 and will you have update on v6?
