Change I2C Speed

[Bingo]

How change I2C speed in program

#include <18F452.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=2000000)
#use I2C(MASTER, sda=PIN_C4, scl=PIN_C3, Fast)

main(){
...
void pump1(void){
...
}
change speed I2C Slow
void pump2(void){
...
}
change speed I2C Fast
...
}

Set the SSPADD register to the value that will give you your new required buad rate. Check the datasheet of the PIC you are using to determine that value.

The compiler can handle this, with HW and Software I2C:
