Try changing the 1000 in line 658 to 10000. Your EC seems to take more than 1 ms to respond. The old behavior was 10 ms which I thought was too long but apparently your system requires this. BTW, what are the guidelines for DELAY vs. msleep? I'm holding a mutex for the local EC for up to 10 ms in that case, in increments of DELAY(10). I would think that somewhere around 1 ms, the delay needs to become an msleep so other device interrupts can occur (i.e. EcGpeHandler). I'm thinking about having the loop up to 1 ms be based on DELAY, and then 9 calls to msleep(..., 1) for the really slow devices. Let me know what you think is best. -NateReceived on Wed Jul 09 2003 - 09:34:51 UTC
