Globals vs. Locals for ADC.

[FWFan]

Hi All,

I tried to use global (before main) to hold my ADC capture but it does not work.

But if I use local, the ADC result would be stored sucessfully.

Do you guys have any thoughts?

The reason I need to store my ADC globally is because I will need

to transfer it when I do my IIC isr.

I'm including my code for reference.

Thank you,

FWFan

Hello,

maybe it helps to declare your global variable as volatile

Thank you Eckhard.
