Improvment key event detection:
In previous version the evaluation of a button event was called in the 100ms callback. Assuming an event is signaled at the in line for 100ms there is a potential risk to loose a button event. To avoid this scenarion the evaluation function was moved into the extint callback (called ~50+xms) and the line readback tim was reduced to 40ms.
Reminder: This function is not called in the main loop because the main loop is not executed in UART mode => movement would cause key events to not beeing detected

1 # How to Create From Scratch a Project for _CPU2-RTE_ Code #
|
|
2
|
|
3 Follow the same procedure than for [CPU1](Detailed CPU1-Discovery Project.md), with changes:
|
|
4
|
|
5 - Create a new _board_ for processor:
|
|
6 > Series: `STM32F4`
|
|
7 > Mcu: `STM32F411xE`
|
|
8 > Debug: `JTAG`
|
|
9
|
|
10 - Add `Small_CPU` linked source directory (instead of _Discovery_)
|
|
11
|
|
12 - Use linker script `OSTC4/Small_CPU/CPU2-F411.ld` |
