Hello,

I am using flowcode v5 on a pic16f1827.

I have a xtal running a 24Mhz and i have set i2c speed to 1Mhz, but i get this : (clock is a 250Kz instead of 1Mhz)

SCL :

My other problem is the time beetween two frames : i have 2.4ms but i haven't any delay in my software. So how to reduce this time ?.

Hello,

I have found the problem, there was a bug in PIC_CAL_I2C.C on sppadd register.
I have several computers and i have forget to update one of them.
This problem is corrected in 5.5 version.

I have also see the delay between data frames, i have to modify this file to reduce it.

Is it possible to make this configurable in the component box ?

Best regards.
