Hi,
I have configure the eCap to read speed following the example on technical reference manual, 33.3.1 Example 1 - Absolute Time-Stamp Operation Rising Edge Trigger, page 1937.
Among all the HALCogen generated code files, where do I put the code that I want to be executed when a CAP4 interruption happens?
I read that the interrupts should be written in the notification.c file, but this looks to me like a definition of a fuction ( void ecapNotification(ecapBASE_t *ecap,uint16 flags)), so if I write it there do I need to call it (
ecapNotification(ecapREG1,ecapInt_CEVT4s) ) in the sys_main.c file?
Thanks a lot
Hello Zheng,
To generate interrupt, 3 steps should be done properly:
1. Enable the interrupt in module level:
2. Enable the interrupt in VIM level: eCAP1 in this example
3. Enable the interrupt in CPU level: clear the I or F bit in CPSR register, or call the function
_enable_IRQ();
