Unless this is just for debugging purposes, having a main() exec while loop with no statements in it and then having all the work done in the interrupt handler is ineffective programming. In these sce ... |

Look in the PIC datasheet, Figure 15-7.
What are the pins used for hardware I2C?
They are not the same pins you have defined.
In a slave you must always use the real I2C hardware. For a master it ... |

hi,
I have a project that requires I2C communication between one master (PIC18F4550) and three slave (two PIC18F4550 and one DSPIC30F4011) but the I2C communication does not work. The SCL pin is alwa ... |

Examples you gave used the SPI interrupt. Is it possible to do it without using the interrupt?
Thank you. |
