Hello BOB,
After you send email to me , please mentioned me at here, or maybe i will ignore your email.
About your project, your interrupt vector have not write to the vector table , while it also have other
errors, so i refer to your demand create one new project , add two component.
The TimerInt component is usd for timer interrupt , the BitIO component is used for gpio to toggle LED.
Configure the Timer interrupt period to 10ms :
,
For i have not the board, so i have not test it , you can test it on your side , check whether it can enter
the interrupt function :

I use the port A-3, if i'm wrong , you can change it on the BITIO component .
Hope it helps
Have a great day,
Alice
