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. | |
Changes from V3.0.1 | |
