[External apps] Allow access to ITCM RAM and reduce slot size #1869

RedGl0w · 2021-09-12T13:11:25Z

All these changes are made in order to enable porting old external apps (from zardam) to epsilon 16.
These changes were adviced by Ecco
To-do :

change USB string descriptors
move apps storage
try to check if it works
rename all ld vars that need to be changed, and continue trying to have the right value for everything
change the ASCII arts in ld
in apps/external_app/eadk_userland.c, change slot detection (and change it in eadk too)

This prevents the timer from activating, and in turn dirtying the battery icon, when the OnOff button is held for a long time.

Step 1: draw_string

for external apps

The solver no longer gives solutions for equations such as x=int(1/t,t,0,1) or x^2=u(0) for u(n)=1/n.

This timer will be used to periodically poll the keyboard while a key is pressed, to detect key presses on the same column.

When TIM5 fires, the keyboard is polled. If no keys are pressed, the timer is not relaunched.

The search for a point of interest cannot work on intervals that contain zero. For x large enough, when searching towards zero, the step would be greater than x, causing its new value to be of opposite sign.

Make sure arg(0) = undef

Remove false assertions and add space for signature

An end-point reset was added to fix a enumeration problem. But, it triggered another issue: the calculator freezes because of a SEDET (end of session) detection. Plus, the initial bug doesn't seem to exist now.
