/*
 * (12) Try move pages to SD-CARD reader FatFS
 * TODO
 * 	OK 1) Try create minimal <index.html> to SD-READER, include FatFS from  <02_m1284p_FATFS_Chang_tst> and test working
 * 	OK 2) Read all pages from (11) to folder <WWW> this project, then move it in root folder SD-Reader and test working
 * 	OK 3) Clean code (done on v2.4b)
 * 	OK 4) Remove unused files from project (done on v2.4b)
 * 	OK 5) Need to handle <FIL fs> for every opened socket!! Because without this server is freeze, while download several large files
 * 	 at once from SD-CARD. (done on v2.4c)
 * 	 				Add and debug f_open(&fs, ..)/??f_close(&fs, ..) to:
 * 	 				http_process_handler_avr (here actually already implemented..)
 * 	 				OK + add f_open(&fs, ..) in <httpServer_run_avr(..)>  STATE_HTTP_RES_INPROC before <send_http_response_body_avr(..)>
 * 	 				f_close(&fs) add to <send_http_response_body_avr(..)> and comment out in  <httpServer_run_avr(..)>
 * 	 Works stable but download speed slow (~40-50kb/sec ~80kb/sec with SPI 4MHZ && _HTTPSERVER_DEBUG_ = ON), because on every download file for every transfer TCP-IP packet proceed sequence: f_open(&fs, ..)/f_lseek(&fs, /f_close(&fs, ..)
 *	OK 6) Optimize (5) - Add to <_st_http_socket> structure <FIL fs> to avoid multiple re-open downloaded file
 *	Works faster: ~80kb/sec with SPI 4MHZ && _HTTPSERVER_DEBUG_ = ON, ~110kb/sec SPI 4MHZ && _HTTPSERVER_DEBUG_ = OFF, ~150kb/sec ~80kb/sec with SPI 8MHZ && _HTTPSERVER_DEBUG_ = OFF
 *	(done on v2.4d)
 *
 * (11) Try move all pages saved at <webpage.h> from RAM to FLASH address space
 * Example of flash data access look at:
 * <01_m1284p_bb00_minimum_PSTR_webpage_test>
 * <09_m1284p_WIZNET_simple_webserver>
 *
 * Success initial porting on 10/12/2018 - FREE RAM on webserver: 7936 bytes (From total 16kbytes)!
 * NEED further optimization to AVR_RAM->AVR_FLASH point (damn Harvard architecture :( )!
 *
 * It works on AtMega1284p(16kbytes RAM), but need TODO finish (DONE on v2.3b 12/12/2018)!!
 *
 * TODO DONE:
 * After v2.3 optimization:
 * 	(+4kb HTTP Buffers READ-WRITE(with HTTPD_MAX_BUF_SIZE	2048 see <globals.h>)) : FREE RAM on webserver: 10372 bytes - much better! (RAM enough for AtMega1284/AtMega2560 ie. AVR with 8-16Kb RAM)
 * 	(+1kb HTTP Buffers READ-WRITE(with HTTPD_MAX_BUF_SIZE	 512 see <globals.h>)) : FREE RAM on webserver: 13444 bytes - awesome! 	   (RAM enough for AtMega644/AtMega128   ie. AVR with 4Kb RAM)
 *
 * OK 1) Father optimization <httpParser.c> / <httpParser.h> (v2.3 12/12/2018)
 * OK 2) Father optimization <httpUtil.c> / <httpUtil.h> (v2.3 12/12/2018)
 * OK 3) Rename httpServer.*->httpServer_avr.*, httpParser.*->httpParser_avr.*, httpUtil.*->httpUtil_avr.* (v2.3b 12/12/2018)
 * 		 Actually made another way: rename parent folder <http> to <http_avr>
 * OK 4) Fix not correct showed value on <ain_gauge.html> (v2.2 12/12/2018)
 * OK 5) Correct indentation in all <*.html> and <*.js> sources and repack it again in <webpage.h>. (v2.2 12/12/2018)
 * OK 6) Add <favicon.ico> to webserver (v2.1 12/12/2018) + also added binary files support in webserver via: <reg_httpServer_binContent_avr()..>, bin2hex_v2.py
 * 7) Publish sources in my github, wiznetmuseim, avrfreaks etc.. (optional)
 *
 * (10) Try repeat example HTTPServer_LPC11E36_LPCXpresso on AVR Mega1284p (All pages still in RAM)
 * Here used to WEB-server handle cgi-like requests, with AJAX + JSON
 * Description here:
 * http://wiznetmuseum.com/portfolio-items/w5500-evb-web-server/
 *
 * To better undestand AJAX look here (actually here used AJAX + XHTML):
 * https://startingelectronics.org/tutorials/arduino/ethernet-shield-web-server-tutorial/web-server-read-switch-using-AJAX/
 * https://startingelectronics.org/tutorials/arduino/ethernet-shield-web-server-tutorial/web-server-read-switch-automatically-using-AJAX/

 * https://startingelectronics.org/tutorials/arduino/ethernet-shield-web-server-tutorial/SD-card-IO/
 *
 * To online encode text file to C source use online utility (Text->Cpp):
 * https://tomeko.net/online_tools/cpp_text_escape.php?lang=en
 * add option <split output into multiple lines> (this is for good reading into browser, as source code)
 * after that insert in any text editor and replace <\n"> sequence to <\n"\> (this is for recognize multiple string into C-source headers)
 *
 * For prepare binary data (some image data, like favicon.ico) use <bin2hex_v2.py> script.
 * Example usage:
 * >bin2hex_v2.py favicon.ico
 * >out favicon_ico.h
 * After that insert into end <webpage.h> content from favicon.ico;
 * Then use this resource in www server like (look in <main.c>):
 * reg_httpServer_binContent_avr(PSTR("favicon.ico"),favicon_ico, (uint32_t)sizeof(favicon_ico));				// favicon.ico 		: webserver icon
 *
 *
 *
 * Also can use File->HEX (BIN2HEX) - for prepare images for example (bin2hex_v2.py BETTER SUIT for AVR!!):
 * https://tomeko.net/online_tools/file_to_hex.php?lang=en
 *
 * (9) Simple webserver, based on <wiznetweb.c> code from:
 * http://www.ermicro.com/blog/?p=1773
 * Article: Integrating Wiznet W5100, WIZ811MJ network module with Atmel AVR Microcontroller
 *
 * (3) Trying WIZNET5500 init with using official Wiznet ioLibrary_Driver
 * working ping on static IP
 * LED1 = ON when phy_link detected
 * and loopback test on TCP-IP:5000 and UDP:3000 ports.
 * use Hercules terminal utility to check network connection see:
