Changes from V3.0.0
|
|
+ ISRcode pulled inline to reduce stack-usage.
|
|
|
|
+ Added functionality to only call vTaskSwitchContext() once
|
|
when handling multiple interruptsources in a single interruptcall.
|
|
|
|
+ Filename changed to a .c extension to allow stepping through code
|
|
using F7.
