Hey all,
I am currently working on the circular buffer with the PIC18F67J94 and I was wondering about the size of the buffer. How big can it be? For example, the UART will have a 'one' deep hard ... |

Hey all,
After reading in the CCS C Compiler manual updated in May 2015, I still do not clearly understand what ERRORS mean for the #USE RS232 preprocessor directives. I have used it in my previo ... |

Shouldn't the RTS and CTS line be way easier to control than this? For example, I am using a PIC18F67J94 and I am setting up my port as follow:
// RS-232 Serial Port setup
#USE RS232(BAUD=115200, ... |

Certain PICs microcontrollers have remappable I/O pins for peripheral devices but it is not clearly indicated in the datasheet. For example, the PIC18F67J94 has four groups of remappable pins so for ... |

It is fairly simple. Just not explained very well in the datasheet. Flipping pins through my design and adding jumpers was the only option for the prototype.
Thank you very much for your help t ... |

The PIC18FxxJ94 family is really picky about which pins can be assigned to which peripheral. The compiler is generating errors because you're trying to assign pins to peripherals that aren't allowed. ... |
