Posted on May 17, 2011 at 10:00Many thanks dear.....Your suggestions helped me solve the problem. I disabled all the pheripheral connects for the TX pins and configured uart2 before uart0. Now all the three uarts are working fine with there Rx inter...
Posted on May 17, 2011 at 10:00By using simultaneously UART 0/1/2 - does this mean, when all had the rx interrupt enabled?I have all the interrupts enabled at all times and am using the standard 91x_it.c file to access IRQ.
Posted on May 17, 2011 at 10:00Yes all have the same hardware. They use the same Drivers and the rx is through a 4 channel opto coupler, one channel for each UART.The waveform when checked on oscilloscope was the same for all MCU rx pins.
Posted on May 17, 2011 at 10:00Can you please send me your configuration code. I have checked all the datasheets and application notes but no difference has been give for any of the UARTS.
