| Good. At least you got there once PCM pointed out how to get 10bit operation.
It sounded like a hardware problem. Lesson is to never 'assume' pins will pull up/down.... I've got one more question ... |

| It was a very, very dumb hardware thing. There's a reset pin on the AD5263 that I thought had a pull-up on it but it needed to be tied high. I *really* appreciate y'all helping me and am pleased wit ... | |

| OK I just tried that I am indeed seeing 10 bit transfers on the scope now. Very cool. Still, the resistance on the 0 address of AD5263 is just staying the same. I think I need to take another look at ... | |

From what I can tell, it's impossible to get spi_xfer to do anything besides a multiple of 8 bit ... |

I've had issues where moving a comment up or down a line would prevent the debugger from working, so I've certainly seen odd things 
Was it an int8 by any chance? We had an issue where another in ... |

Forum: General CCS C Discussion Posted: Mon Jan 14, 2019 1:25 pm Subject: fastest reasonable UART baud rate between two PICs |
| this info is so helpful, thank you!
In my application I'm in the same enclosure, the PICs are on different PCBs connected via IDC cable. So I think I'll give a baud rate of 1M a go. |

I'm using two PIC16F1527s to communicate with each other via the hardware UART. I'm curious if you guys have any advice for fastest reasonable speed. I'm running the processors at 20MH ... |

Just a note: open and read (or skim  ) the processor's header file. This would be the 16F1527.h for example. Near the bottom (usually) is a list of all supported interrupts.

| I just downloaded the datasheet, it has 2 HW UARTs and they're on fixed pins so easy to use providing your compiler version has it. Simply read about #use RS232( streams=....)
