#138064 - Serial interrupt Responding to: ???'s previous message |
whilst I haven't checkedthe aduc848 specs, my experience with other parts in the family suggest that the uart is the same as the standard 8051. You have an interrupt for the receive data - this is also shared with the tx. I would suggest that you make the uart tx interrupt driven also as some weirdness might occur - of TI gets set by the uart, it will interrupt but the ISR doesn't handle tx interrupts, thus the interrupt keeps firing. With the printf in the rx isr, this is guaranteed! I sugggest you get hold of a simulator which should show you exactly what is happening. |
