Hi all,
in my project, I've three main processes (ethernet stack, gui-tft and usart interface). The gui routine (for the whole user interface including touch, tft, encoder) takes its time, therefore the ethernet stack part uses an interrupt (execution all 0.1ms). It's important to process these ethernet ptks very fast.
The usart also uses an interrupt if a pkt will be receveid; therefore it is possible to get nested interrupts. Because it is possible to get two or more data bytes by the usart during one ethernet interrupt (0.1ms)...
Is there a option / possibility to work with nested interrupts (a work around)? To get all events? The controller I'm using is the AT91SAM9263 from Atmel.
best regards Hannes
