What MCU/Processor/Board and compiler are you using?
STM32F407 and GCC
What do you want to achieve?
Interrupt or abort the task handler after a certain time or if an external flag is set
What have you tried so far?
Read about the task handling but it says the task can’t interrupt each over.
I run LittlevGL on the STM32F4 and in my application I have some continouse data input stream which should be filtepass through a bi-quad filter stage and saved to a SD card. The problem I face now is that large arrays to redraw on the screen took to much time and the datastream is corrupted. The custom board I use has no external RAM so I can’t expand the input buffer any further.
My idea was to interrupt the task_handler if on of the two input buffers is full, call the filter and the write function and then to further execute the task_handler, but I couldn’t find any describtion in the doku how to do it.
Is there any chance to interrupt the task_handler or implement an interrupting task in it?
