Strange function return values, often. Even simple if-statements going wrong. We have now put all interrupts in the same level. - Problems gone. (...except we have a bit more than acceptable latency for the service we before had in high prio... so as a whole the design is not working... need to redesign long-time blocking interrupt routines...) -- Morgan Olsson -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
