#82883 - Serial port interupt and multitasking |
Hi,all.
My config: at89c51ed2, rtx51 tiny OS. PROBLEM: Some days ago I've written code for 4 tasks: ethernet, spi, lcd, i/o. Everything worked fine. But After this I've added such a code: ES = 1 (and code for serial port lowest priority: IPH0&= 0xEF;IPL0&= 0xEF;). After this nothing works. Probably all tasks are blocked, maybe there is another reason. So, does anybody know: what's this? |
