Honestly, the CS concept for the QSPI is very limiting. I have written a QSPI driver for an MCF5225x that totally bypasses the QSPI CS handling and uses GPIO for CS. First of all, you are no longer limited to the 4 CSs (and don't have to add external hardware to support up to 16 SPI devices). You a...

rnixon and Ridgeglider, thanks for excellent introduction to the (new for me) method of event-driven communication between the low level and the middle level using QS flags. The method with select(), as I understand, is implemented in the library "Command Processor", which was successfuly ...

Ridgeglider, Some events will be generated by certain background processing of UART and Telnet input. The library's Command Processor is proven to be suitable for this subsystem during my previous project. Is exist proven way to arrange as FDs (virtual serial ports?) those event sources, which imple...

rnixon, I intend to generate most of the events by some background processing of analog and digital inputs. The other events will be generated by some background processing of UART input. The system deadline is 10 ms to 100 ms. My primary interest is a good arrangement of the event flow from the low...

Can somebody recommend a good code and documentation for template (or example) of background recognition of some events and calling the user-filled functions?
The library Telnet/Serial Command Processor is seem too complex for such a template.

My application uses IRQ5, IRQ3, and IRQ1 pins as the external interrupt sources using NB INTERRUPT macro. No problem with IRQ5 is detected. Even if something (other than the EPORT, which would use the same vector)) is using IRQ5, you should be able to add another ISR at level 5 by varying the priori...

Why to violate the regular network behavior?
HTTP is intended for short transactions. After finishing the HTTP transaction, close the connection. The running HTTP service is listening for a future connection at port 80.

Do you need Telnet connection without the well known TCP port 23?
Why to confuse with port 80, which is well known for HTTP?
You can arrange any unused TCP port.
