Hello All,
in the CMSIS there is a framework for UART communication. However I have to know in advance how many characters to receive.
I would have expected that UART driver write to kind of circular buffer permanently.
Because usually I do not know WHEN there is communication and HOW MANY data will be transmitted. I assume that when I abort the receive function with timeout and start again the receive function that in the mean time I might loose data on the hardware. Because if the receive function is not active no DATA AVAILABLE event will be handled.
In my real live projects I only use the UART transmit functions and reimplement my custom receive functions.
How does CMSIS address this issue? What is the best practice here?
Best regards.
Adib.

Exactly so and I've always done the same.
Actually, I agree with all you wrote there.
Unfortunately, in my experience I'd say that it's not a very common point of view; and for various reasons. Just yesterday a new manager was forced on me. He comes from a Windows/Microsoft background and thinks embedded systems must be developed in the same way. Why develop a component when you can just drop an existing one from someone else into a project? Heated discussions ahead.
