I'm working on a project where I read data from a controller and write it to a console. To handle this, I'm using interrupts. In the main while loop, I continuously read data from the controller. When the console starts requesting data, an interrupt is triggered, and I write the data to the console.
The problem is that after returning from the interrupt, I get stuck in a get_blocking function. This happens because the controller continues sending data while the interrupt is being handled.
I want to use an interrupt so I don't have to worry about the timing of when the console polls for the controller data.
Is there a way to make sure that when I return from the interrupt, I always start at the beginning of the function that reads data from the controller? or a different approach I should take?

Code:
