Subject: Fix compiler warning in timers.c/h that are only seen when the file is compiled on... 
X-Git-Tag: V7.1.0~23
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=36f74cc8f9410bf2dfda7288a9b89459dec9c0fc;p=freertos

Fix compiler warning in timers.c/h that are only seen when the file is compiled on 8 bit devices.
Update example source code in timers.h so the parameter names match those in timers.c.
Fix "known issue" bug in xTaskResumeFromISR() (which was missing a critical section).
