| Turns out that its the connector that has resulted in UART to hang (Signals momentarily connecting before the GND and Supply.)
I tested out four different connectors 1)Dupont 2.00mm 2) Molex 2510 ... |

| I use a molex 2510 connector, and yes, the odds of a working UART does seem to depend on the connector.
The ground and supply are routed from the main board. minimal potential difference between ... |

| Thanks for the response,
As said, I tried to check the clock speed when the UART doesn't work. Seems to be alright. Is there a way to initialize UART dynamically in the program after a delay ( I am ... |

| Yes, I have the "errors" turned on in #use_rs232
The PIC gets damaged over-time by hot-plugging, one of my chip had to be replaced. Replaced chip works fine. It is not fixable by resta ... |

| Hi,
I am interfacing three PIC16F1947's with UART (RS232 protocol). For instance lets name the three PICs as A, B and C. PIC 'A' has two UART ports active. PIC 'B' and 'C' have one port acti ... |
