115200 extra interrupts per second of 30 to 60 machine codes is probably feasible on a 50 MHz mcu = 20% CPU but it does not sound like an interesting idea. Try an STM32 with its 5 uarts?

Hi all,
it is possible to program a software uart for the sum impulse input of the lpc2148 autopilots?
Or is the interrupt load to large for 115k baud and a six charter stream?
