* LCD/OLED Implementation * OLED basic working 32 *132 display * LCD/OLED startup ok * Simplified setup * Missing freememory include * Format Width Allow right padding number width in String format * Intermediate scroll * Compile issues with no LCD * Clean buffers at startup * Support for format left padded numbers * Smarter Scrolling And forced start messages Free Ram in slot 2 * LCD tidying Neater setup block in .ino. Dropped unnecessary code No-scroll if display not full * Missing %E format support This is used in WifiInterface checkForOK * Wifi correction and memory guard
