#142551 - No TX interrupt servicing Responding to: ???'s previous message |
1. it is worth formatting your code for the forum.
2. either post the complete code or at least stick to one language. I can see nothing in your assembly code that the C compiler would have written any worse. "while (TI == 0) ;" or "RI = 0;" seem pretty straightforward to a C compiler. 3. you appear to have a UART ISR for receiving and not using interrupts for transmitting. I would suggest that you either have TX and RX interrupt driven or not at all. So every time you transmit a character the ISR is called but you never service a TX interrupt. David. |
