Module layout:

// Goodies: #include "../common.h"

// Mandatory #include "../actions.h"

// All exported names (currently all names) should be prepended with module name. Use "m_" prefix for best results.

// Redraw handler can have any name as long as it follows the signature: void module_redraw(const uint8_t force); // force decides whether a full screen update is necessary or the module can expect that it controlled the screen in the previous frame (for partial updates) // This function can access the screen, but only 2 lower lines

// Action handling function const module_actions_t* module_select(const uint8_t state); // state notifies if the button was depressed (true) or released (false) // return value: a structure of left-right button actions or NULL if they should stay unmodified. // This function is run from an interrupt and therefore must not access the screen or do any expensive calculations

// Signature is the module icon. 8 bytes left-to-right, MSB=down #define module_signature {0b10011001, 0b01011010, 0b00100100, 0b00011000, 0b00100100, 0b01011010, 0b10011001}

// Basic entry for module #define module_record {&module_redraw, &module_select, module_signature}

// Last modification: add module_record reference inside base.c modules[] table.
