In most systems the mic rocontroller is the master and the exte rnal peripheral devices are slaves. In these cases this application note can b e used to attach I2C slaves to the PIC1 6CXXX (the master) microcontroller. The multi-master system is not implemented because it is extremely difficult to meet all the I2C Bus timing specificat ions using software. For a true slave o r multi-master system, some interface h ardware is necessary (like START & STOP bit detection). In addition to the low level single master I2C routines, a co llection of high level routines with va rious message stru . |
